Description

[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS none [Background technology]

[0002] Various classes of printers are commonly equipped with cutter mechanisms designed and positioned to sever individual portions of a continuous supply of printable media before the printed product is removed by a user. For example, a printer designed to print adhesive labels may accept a continuous supply of labels (e.g., a plurality of adhesive labels positioned along a continuous strip of liner material), print desired text or graphics on each label, and then cut off the supply of labels one by one as they exit the printer so that the labels can be conveniently removed by a user.

[0003] In some cases, particularly in the context of high-volume printing environments (e.g., printing product labels in a commercial context), these cutting mechanisms may be prone to deterioration or malfunction due to repeated use. In the example above, adhesive applied to a supply of adhesive labels may build up on the blade of the cutter mechanism over time. Similar problems may arise in other situations. For example, certain classes of printable media (e.g., magnets) may cause metal particles or other undesirable particulate matter to accumulate on the blade. Summary of the Invention [Problem to be solved by the invention]

[0004] Over time, material that builds up on the blade impairs the quality of cuts performed by the cutter mechanism. If left unattended, such buildup can further shorten the life of the cutter mechanism or the printer in which it is installed. To maintain cut quality and avoid damage or malfunction of the cutter mechanism, customers may be required to perform maintenance on the blade or other components of the cutter mechanism, which can lead to increased costs and inconvenience. Therefore, a need exists for a cutter mechanism that eliminates the ability of undesirable materials (e.g., adhesives, metals, etc.) to build up on the blade over time as a result of repeated use. In particular, a need exists for a cutter mechanism that reduces buildup on the blade compared to existing solutions and has the ability to automatically remove or clean material that builds up on the blade without requiring maintenance. [Means for solving the problem]

[0005] The present disclosure relates to a cutter assembly for use in a printer.

[0006] A cutter assembly for use in a printer is disclosed. The cutter assembly includes a carriage configured for translational movement along a guide rail having first and second ends, a blade held within the carriage, a breaker bar extending along a path of motion of the blade, a belt engaging at least a portion of the carriage, one or more pulleys configured to generate linear motion of the belt, and a clamp positioned to engage the carriage at one or both of the first and second ends. Engagement between the clamp and the carriage causes a self-cleaning action of the blade.

[0007] In some embodiments, the cutter assembly further includes one or more gears configured to drive rotation of at least one of the one or more pulleys, and a motor configured to drive rotation of at least one of the one or more gears.

[0008] In some aspects, the clamp further includes one or more deflection tabs positioned to be engaged by the carriage at one or both of the first end and the second end.

[0017] In some embodiments, the pulley subassembly includes five pulleys.

[0018] In some embodiments, the cutter assembly further includes a disrupter bar extending along the path of motion of the blade.

[0019] In some embodiments, the disrupter bar is not magnetic.

[0020] In some embodiments, the blade includes a cutting edge defined by an angle between about 40° and about 50°.

[0021] In some embodiments, the cutter assembly further includes a motor configured to engage at least one of the one or more gears to drive movement of the belt.

[0022] In some embodiments, the cutter assembly further includes at least one switch positioned to be engaged by the blade subassembly, the at least one switch configured to stop the motor when engaged by the blade subassembly.

[0023] In some aspects, the clamp is configured to release a portion of the printable media when the blade subassembly engages the clamping subassembly.

[0024] In some aspects, engagement between the gear subassembly and the clamping subassembly causes a self-cleaning action of the blade.

[0025] A method for severing a supply of media in a printer is disclosed. The method involves feeding a supply of media through an inlet in a frame so that a desired portion of the supply of media extends beyond a breaker bar coupled to the frame. The frame supports a blade subassembly including a carriage and a blade carried by the carriage, occupying a default position; a pulley subassembly including a belt coupled to the carriage and configured for linear movement around one or more pulleys; and a clamping subassembly configured to be releasably engaged by the carriage. The method further involves moving the carriage across the frame and generating linear movement of the belt such that the blade severs the supply of media along an edge of the breaker bar. The method further includes retracting the supply of media away from the inlet. The method further includes returning the blade subassembly to its default position. The clamping subassembly includes a clamp configured to be engaged by the carriage to cause an automatic cleaning action of the blade in response to engagement with the carriage.

That is, the presently disclosed embodiments are not intended to be limited to the embodiments shown, but rather are to be accorded the widest scope consistent with the principles and features disclosed herein. The following detailed description should be read with reference to the figures, in which like elements in different figures have the same reference numerals. Those skilled in the art will recognize that the examples provided herein have many useful alternatives and fall within the scope of the presently disclosed embodiments.

[0030] Additionally, while the following discussion may describe features associated with particular devices or embodiments, it is understood that additional devices and / or features can be used in conjunction with the described systems and methods, and that the devices and features discussed are used to provide examples of possible embodiments without limitation.

[0031] The present disclosure relates to a cutter assembly designed to cut a desired portion of a supply of printable media, for example, before the desired portion is removed by a user. The cutter assembly can be used with various types of printers. For example, the cutter assembly can be used with one or more of an inkjet printer, a thermal printer, a laser printer, or any other suitable device capable of printing text, images, or other graphics onto printable media.

[0032] 1-3, an exemplary inkjet printer 100 is provided in the form of a housing 101 defining a first end 102 (e.g., at the front of the printer) and an opposing second end 104 (e.g., at the rear of the printer). The housing 101 of the inkjet printer 100 is defined by a base portion 106 and an enclosure cover 108. The base portion 106 and the enclosure cover 108 may be hinged or otherwise coupled to one another such that the enclosure cover 108 can be removably opened and / or attached to provide access to the internal components of the inkjet printer 100 and to allow installation and maintenance of the internal components. The enclosure cover 108 may be coupled to the base portion 106 by a hinge 124 (see FIG. 3) or other attachment means.

[0033] The inkjet printer 100 may include one or more indicators 110 and one or more buttons 112 disposed on the enclosure cover 108. As shown in FIG. 1 , the inkjet printer 100 includes two indicators 110 and three buttons 112. However, the inkjet printer 100 may include any number of indicators 110 and / or buttons 112. The indicators 110 may be positioned to alert a user to various operational states of the inkjet printer 100. In some cases, the indicators 110 may be provided in the form of light-emitting diodes (LEDs) configured to indicate to a user when the inkjet printer 100 is powered on or low on ink. Alternatively, the indicators 110 may be used for any other suitable purpose. The buttons 112 may be positioned to allow a user to operate, service, or otherwise interface with the inkjet printer 100. For example, the buttons 112 may be configured to allow a user to load new printable media into the inkjet printer 100. In some forms, depressing or otherwise actuating the button 112 will cause the enclosure cover 108 to separate from the base portion 106 .

[0034] Inkjet printer 100 may include a linear exit slot 114 positioned on and extending through base portion 106. For example, exit slot 114 may be provided in the form of an "entrance" or opening located on base portion 106 at first end 102. Media printed by inkjet printer 100 may exit inkjet printer 100 at exit slot 114, where it may be removed by a user.

[0035] 2, the inkjet printer 100 may further include a control area 116 disposed on the base portion 106. For example, the control area 116 may be disposed on the base portion 106 at the second end 104 and may include a power switch 118, an input port 120, and a power port 122. The power port 122 may facilitate coupling between the inkjet printer 100 and an external power source such that a user may power on the inkjet printer 100 using the power switch 118. The input port 120 may facilitate coupling and communication between the inkjet printer 100 and an external device (such as, for example, a smart phone, desktop computer, or digital camera).

[0036] 3, the enclosure cover 108 of the inkjet printer 100 is designed to rotate to an open configuration. The enclosure cover 108 may be rotatable about a connection axis formed by a hinge 124. Thus, a user can place the inkjet printer 100 in the open configuration by lifting the enclosure cover 108 off the base portion 106 and rotating the cover about the hinge 124.

[0037] The base portion 106 may include a media area 126 proximate the first end 102 and a print area 128 proximate the second end 104. The media area 126 may include a mount 130 that functions to support a media 132 (e.g., a roll of printable labels) for printing. The print area 128 may include one or more of a printhead (not shown), ink cartridges (not shown), electronic circuitry or a controller (not shown), a waste area (not shown), or any other element or mechanism that facilitates printing an image, text, or other graphic onto the media 132.

[0038] Although a particular exemplary inkjet printer 100 has been described, it should be appreciated that an inkjet printer 100 suitable for use with the printer-cutter mechanism disclosed herein may include or exclude additional components known in the art.

[0039] 4-6, an exemplary thermal printer 160 suitable for use with the printer-cutting mechanism herein is shown. The thermal printer 160 may be provided in the form of a direct thermal printer, a thermal transfer printer, a handheld thermal printer, or any other equivalent device. The thermal printer 160 includes a body 162 defined by a first body portion 162A and an opposing second body portion 162B. The thermal printer 160 may include a first cover panel 164 and a second cover panel 166. The first and second body portions 162A, 162B, together with the first and second cover panels 164, 166, may define an enclosure that holds the internal components of the thermal printer 160. The first cover panel 164 may include one or more of a release latch 168, a display 170, and a power button 172. The thermal printer 160 can include an output area 174 disposed beneath the first cover panel 164 and extending between the first body portion 162A and the second body portion 162B.

[0040] 5, the thermal printer 160 can be designed to be articulated between a closed position, in which the second cover panel 166 is flush with the first cover panel 164, and an open position (see FIG. 6), thereby exposing the components enclosed within the first and second body portions 162A, 162B and the first and second cover panels 164, 166. A release latch 168 can engage the connection between the first and second cover panels 164, 166 such that a user 176 can separate or disconnect the first and second cover panels 164, 166 by pulling the release latch 168. Each of the first and second cover panels 164, 166 can be hingedly connected to the first and second body portions 162A, 162B through hinges (not shown) or other connection means. That is, when the user 176 pulls the release latch 168, the user 176 can then move each of the first and second cover panels 164, 166 up and away from the enclosed space, thereby exposing the internal components of the thermal printer 160.

[0041] 6 , the thermal printer 160 may include a print head 178 and a ribbon holder 180 positioned on the inner surface of the first cover panel 164. A label well 182 may be positioned beneath the second cover panel 166, and one or more media guides 184 may be positioned between the label well 182 and the output area 174. The thermal printer 160 may include a cutter 186 positioned between the media guide 184 and the output area 174. Thus, printable media (e.g., a roll of printable labels) may be placed in the label well 182 before the thermal printer 160 is used. Such printable media may be fed through the media guide 184, printed by the print head 178 and a ribbon (not shown) disposed in the ribbon holder 180, cut by the cutter 186, and then removed from the thermal printer 160 through the output area 174. In some cases, the cutter 186 may be provided in the form of a printer cutter mechanism as disclosed herein.

[0042] Although a particular exemplary thermal printer 160 has been described, it should be appreciated that a thermal printer 160 suitable for use with the printer-cutter mechanism disclosed herein may include or exclude additional components known in the art.

[0043] 7-9, an exemplary LED or laser printer 210 may include a housing having a feeder assembly 212, a printer device 214 positioned thereon and supported thereby, and a take-up reel 216. On a front side 218 of the laser printer 210, one or both of the feeder assembly 212 and / or printer device 214 may include a display 220 that allows a user to interact with the laser printer 210 and one or more buttons 222 that may correspond to various settings or functions of the laser printer 210. The feeder assembly may include a front cover 224 positioned on the front side 218 and a top cover 226 positioned opposite the feeder assembly 212. The take-up reel 216 may be positioned on a support plate 228. As best shown in FIG. 8, which shows a rear side 230 of the laser printer 210 without the take-up reel 216, the support plate 228 may be coupled to the rear side 230 by one or more fasteners 232. The laser printer 210 may further include one or more ports 234 , one or more power outlets 236 , and an exit slot 238 positioned on the rear side 230 .

[0044] Referring to FIG. 9 , the front cover 224 and top cover 226 can be opened to expose various internal components of the feeder assembly 212 and the printer device 214, respectively. The internal components of the feeder assembly 212 can be positioned on and supported by a tray 240. The tray 240 can be slidably coupled to the feeder assembly 212 so that it can be retracted when the front cover 224 is opened. The tray 240 of the feeder assembly 212 can support one or more of a spindle pin 242, an extension arm 244, one or more media guides 246, and a stationary bar 248. The spindle pin 242 can provide a rotatable support structure for transfer to the printable media by the printer device 214. The extension arm 244 and the media guide 246 can help support the media or guide the media toward an opening (not shown) through which the media travels from the feeder assembly 212 to the printer device 214. The media can be directed to travel over stationary bar 248 and then enter printer device 214, which can condition the media to attract toner (e.g., by applying an electrical charge to the media).

[0045] The internal components of the printer device 214 may include one or more drum units 250, one or more toner cartridges 252, and one or more LED heads 254. In the exemplary printer of FIG. 9 , the printer device 214 may include four drum units 250, four toner cartridges 252 (e.g., C, M, Y, and K toner), and four LED heads 254. The drum units 250 may be uniformly or substantially uniformly charged with an initial charge. For example, the printer device 214 may include a high-voltage wire or a charging roller (not shown) configured to apply a charge to the drum unit 250. The LED heads 254 may be positioned to direct light toward the drum unit 250, and the light generated by the LED heads 254 may reverse the local charge of the drum unit 250 in the areas illuminated thereby. Thus, the LED heads 254 may selectively direct light toward specific areas of the drum unit 250 that correspond to the image or text being printed.

[0046] Areas of the drum unit 250 that have had their charge reversed by the LED head 254 can attract toner from the toner cartridge 252 (e.g., can impart toner with an opposite charge to that of the area of ​​the drum unit 250 illuminated by the LED head 254). The toner can then be transferred to printable media being fed from the feeder assembly 212 to the printer device 214 as the media (charged by the stationary bar 248) advances across the drum unit 250. The media can then pass through a fuser (not shown), which can be provided in the form of one or more heated rollers that melt the toner, thereby "melting" or otherwise adhering the toner to the media. The printer device 214 can include a fuser release lever 256 that extends upward from the fuser (not shown) to enable a user to lift and remove the fuser from the printer device 214 (e.g., for maintenance).

[0047] In some cases, the printer device 214 may include a laser beam (not shown) and one or more mirrors (not shown) instead of the LED head 254. In these cases, the laser beam may be selectively directed toward the drum unit 250 to reverse localized charges in areas corresponding to the text or image being printed so that toner is attracted to those areas. The laser beam may be stationary, and one or more movable mirrors may be configured to direct the laser beam toward specific areas of the drum unit 250.

[0048] Although a particular exemplary laser printer 210 has been described, it should be appreciated that a laser printer 210 suitable for use with the material holder disclosed herein may include or exclude additional components known in the art.

[0049] Turning now to FIG. 10 , cutter assembly 300 can be designed to sever a desired portion of the printable media either before or after the media supply undergoes transfer. Cutter assembly 300 can be used in conjunction with inkjet printer 100, thermal printer 160, laser printer 210, or any other suitable printing device. For example, cutter assembly 300 can be located adjacent exit slot 114 of inkjet printer 100, output area 174 of thermal printer 160, or exit slot 238 of laser printer 210 to slice the media as it exits the printer. It should be appreciated that cutter assembly 300 can be positioned anywhere along the media travel path such that it can cut the printable media before it exits the printer. Cutter assembly 300 can be located within or otherwise configured for use with the printers disclosed herein in a manner known in the art.

[0050] Cutter assembly 300 is provided in the form of a frame 302 that supports one or more of a blade subassembly 304, a pulley subassembly 306, and a clamping subassembly 308, among others. Pulley subassembly 306 can be operatively coupled to blade subassembly 304 and configured to facilitate operation thereof. For example, a carriage 310 of blade subassembly 304 and a blade 312 retained therein can be positioned for translational movement along a guide rail 314 coupled to frame 302. A belt 316 of pulley subassembly 306 can be coupled to or otherwise engaged with carriage 310 and configured to generate translational movement of carriage 310 along guide rail 314 (e.g., across frame 302).

[0051] In some cases, the pulley subassembly 306 can include one or more gears. In the example of FIG. 10 , a drive gear 318 can be configured to generate rotation of a compound gear 320 connected to multiple pulleys 321 that engage a belt 316. A motor 322 configured to generate rotation of the drive gear 318 can drive translational movement of the blade 312 along the guide rail 314 through engagement between the drive gear 318, the compound gear 320, the pulleys 321, the belt 316, and the carriage 310. In other cases, gears (e.g., the drive gear 318 and the compound gear 320) can be omitted. Thus, the motor 322 can directly engage the pulley 321, and translational movement of the blade 312 along the guide rail 314 can be driven through engagement between the pulleys 321, the belt 316, and the carriage 310.

[0052] Two mechanical switches 324a, 324b in communication with the motor 322 may be supported by the frame 302 and positioned at opposite ends of the guide rail 314. The switches 324a, 324b may be configured to stop the motor 322 (e.g., terminate the movement of the carriage 310) when the carriage 310 reaches either end of its path of movement along the guide rail 314. For example, each switch 324a, 324b may include a trigger 326a, 326b positioned such that at least a portion of the carriage 310 strikes the trigger 326 of one of the switches 324a, 324b when the carriage 310 approaches either end of the guide rail 314. Upon impact, each trigger 326a, 326b may be configured to cause the switch 324 to which it is connected to stop the motor 322. In other cases, switches 324a, 324b may be replaced by electronic sensors or other mechanisms known in the art that are configured to stop motor 322.

[0053] The spring-loaded clamps 328 of the clamping subassembly 308 can be configured to releasably immobilize or limit movement of a portion of the printable media (not shown) during cutting. For example, the clamping subassembly 308 can cause the clamps 328 to apply consistent downward pressure to the supply of media being cut (e.g., holding the media against the breaker bar 330), thereby preventing or reducing rotation of the media relative to the breaker bar 330 during translation of the blade 312. Once the cutting operation is complete, the carriage 310 can be configured to disengage the clamping subassembly 308 and release the media from the breaker bar 330.

[0054] The clamping subassembly 308 may include two angled deflection tabs 332a, 332b positioned proximate the switches 324a, 324b, respectively. The carriage 310 may be configured to engage one of the deflection tabs 332a, 332b when it approaches either end of the guide rail 314. Each engagement between the carriage 310 and one of the deflection tabs 332a, 332b may include the carriage 310 applying an upward force to the deflection tab 332 and the deflection tab 332 applying an opposing downward force to the carriage 310. In this manner, the carriage 310 may lift the clamp 328 by engaging one of the deflection tabs 332a, 332b, thereby releasing media held against the crusher bar 330. At the same time, the deflection tabs 332a, 332b cause downward movement of the carriage 310, which can cause a cleaning action between the blade 312 and the crusher bar 330, as described below with reference to Figures 56 and 58C.

[0055] 11 , the frame 302 may be provided in the form of a rectilinear body 334 defined by a first side 336, an opposing second side 338, a top end 340, and an opposing bottom end 342. The inlet 344 may be provided in the form of a substantially rectilinear opening extending through the body 334 and defined by the first side 346, an opposing second side 348, a top end 350, and an opposing bottom end 352. The first side, second side, top end, and bottom end 346, 348, 350, and 352 of the inlet 344 may correspond to the first side, second side, top end, and bottom end 336, 338, 340, and 342 of the body 334. The body 334 may be provided in the form of any suitable metal, plastic, or composite material. For example, the body 334 may be provided in the form of carbon steel, stainless steel, wrought iron, aluminum, copper, titanium, tin, polycarbonate (PC), acrylonitrile butadiene styrene (ABS), polyvinyl chloride (PVC), polyethylene terephthalate (PET), carbon fiber, fiberglass, or any other suitable material.

[0056] The plurality of mounting holes 354 may be provided in the form of substantially circular openings extending completely through the body 334. The mounting holes 354 may be configured to receive fastening mechanisms (e.g., screws) and may be selectively positioned to support or couple various components of the cutter assembly 300 to the frame 302. For example, one or more mounting holes 354 positioned proximate the junction between the first side 336 and the bottom end 342 of the body 334 may facilitate attachment between the motor 322 and the frame 302. Additionally, the frame 302 includes a motor port 355 configured to receive at least a portion of the motor 322 and positioned proximate the junction between the first side 336 and the bottom end 342 of the body 334.

[0057] The body 334 may include a tab positioned along each of the first side 346 and the second side 348 of the entrance 344 and extending inwardly therefrom. For example, a first tab 356a may be positioned along the first side 346 of the entrance 344, and a second tab 356b may be positioned along the second side 348 of the entrance 344. Each of the tabs 356a, 356b may be positioned in substantially the same location relative to the top end 350 and the bottom end 352 of the entrance 344 (e.g., the tabs 356a and 356b may be horizontally aligned). Each of the tabs 356a, 356b may include one or more mounting holes 354. In some cases, the tabs 356a, 356b may be configured to facilitate attachment between the guide rail 314 and the frame 302.

[0058] 11 , the body 334 may further include a central shelf 358 extending outwardly from and along the bottom end 352 of the entrance 344 and oriented substantially perpendicular to the body 334. Additionally, an anchor 360 may be positioned between the shelf 358 and the bottom end 342 of the body 334, extending outwardly from the frame 302. Each of the shelf 358 and the anchor 360 may be connected to a front surface 361 of the frame 302.

[0059] 12, the blade subassembly 304 may be provided in the form of a carriage 310 configured to hold its blade 312 and / or other components. The carriage 310 may include a carrier 364 and a substantially semicircular cover 366 coupled to the carrier 364 by one or more fasteners 368. The carrier 364 and the cover 366 may at least partially surround the blade 312. Together, the carrier 364 and the cover 366 may form an opening 370 configured to allow at least a portion of the blade 312 to extend downwardly therethrough.

[0060] As best shown in FIG. 13 , the carrier 364 may be movably coupled to or mounted on the guide rail 314 through a substantially T-shaped runner 372 positioned on opposite sides of the cover 366. The runner 372 may be provided in the form of two complementary angle members 374 a, 374 b. Each of the angle members 374 a, 374 b may include an arm 376 a, 376 b terminating in a point 378 a, 378 b extending in a direction substantially perpendicular to the arms 376 a, 376 b extending outward from the carrier 364. The point 378 a of the first angle member 374 a may extend upward relative to the arm 376 a, and the point 378 b of the second angle member 374 b may extend downward relative to the arm 376 b. Arms 376a and 376b may be oriented substantially parallel to one another and may be separated such that a gap 379 is provided therebetween (positioned between arm 376a of angle member 374a and arm 376b of angle member 374b).

[0061] 14 , the carrier 364 may include a substantially semicircular blade region 380 and a peak region 382 disposed thereover. The blade region 380 may include a substantially flat bottom edge 384 extending between two connecting shafts 386 a, 386 b. Each connecting shaft 386 a, 386 b may include a sidewall 388 a, 388 b defining a carrier opening 390 a, 390 b extending through the substantially cylindrical sidewall 388 a, 388 b. Each of the carrier openings 390 a, 390 b may be configured to receive a fastener (e.g., fastener 368) to facilitate coupling between the carrier 364 and the cover 366. In some cases, the carrier openings 390 a, 390 b may be threaded (e.g., configured to receive a fastener 368 having complementary threads). In other cases, the carrier openings 390a, 390b may be configured to securely receive the fasteners 368 by any other suitable mechanism (eg, a press fit).

[0062] A substantially cylindrical first collar 392 may be positioned on and extend outwardly from an inner wall 394 of the blade region 380. In some cases, the first collar 392 may be centered between the two connecting shafts 386a, 386b. The first collar 392 may be oriented substantially parallel to the connecting shafts 386a, 386b and may define a substantially cylindrical first silo 396 therein. A recess 397 having the shape of at least a portion of a circle may surround (e.g., be substantially concentric with) the first collar 392.

[0063] A peak region 382 positioned above the blade region 380 (e.g., positioned opposite the bottom edge 384) may be imparted with a triangular or trapezoidal shape. In some cases, the peak region 382 may include two substantially symmetrical angled walls 398 and an apex 400 where they converge. In some cases, one or more of the angled walls 398 and the apex 400 may be configured to engage the clamping subassembly 308 described above with reference to FIG. 10 during use of the cutter assembly 300. The peak region 382 may be integrally formed with the blade region 380 or may be coupled to and extend upwardly therefrom.

[0064] 15 , each of the angle members 374 a, 374 b may extend linearly between a first end 402 and a second end 404 of the runner 372. The carrier 364 may further include two appendages 406 attached to and extending outwardly from the first angle member 374 a at each of the first and second ends 402, 404. Each appendage 406 may be defined by a vertical wall 408 positioned to be substantially flush with or parallel to the guide rail 314 when the cutter assembly 300 is assembled.

[0065] Each of the angle members 374a, 374b can include a first inner surface 410a and a second inner surface 410b, respectively. Each of the inner surfaces 410a, 410b can extend between the first end 402 and the second end 404 of the runner 372 and can be substantially perpendicular to the vertical wall 408. The first inner surface 410a can have a first raised portion 412a, and the second inner surface 410b can have a second raised portion 412b. The raised portions 412a, 412b can project inwardly (e.g., toward the gap 379) from the inner surfaces 410a, 410b, respectively. The first raised portion 412a can be provided in the form of a substantially rectangular protrusion defined by a substantially smooth surface. The second raised portion 412b may be provided in the form of a substantially rectangular protrusion including a plurality of notches 414 formed along its notch surface 415 (e.g., the surface opposite the first raised portion 412a). The notches 414 may be configured to facilitate engagement between the carrier 364 and the belt 316 of the pulley subassembly 306. In some cases, the notches 414 may be substantially semicircular in shape. In other cases, the notches 414 may be provided with any suitable shape or configuration.

[0066] 16 and 17 , the semicircular cover 366 may be provided in the form of a substantially vertical side wall 416 and an end wall 422 surrounding and projecting outwardly therefrom. The cover 366 is defined by a substantially flat bottom edge 418 and a substantially semicircular top edge 420. The cover 366 may include two wings 424a, 424b coupled to and extending outwardly from the end wall 422. Each of the wings 424a, 424b may include a cover opening 426a, 462b configured to receive a fastener (e.g., fastener 368) to facilitate coupling between the carrier 364 and the cover 366. The cover 366 may further include a rounded, stepped protrusion 428 disposed along and extending from the bottom edge 418 of the side wall 416. In some cases, the protrusion 428 may be positioned substantially equidistant from the two wings 424a, 424b. In other cases, the protrusion 428 can be offset relative to the wings 424a, 424b.

[0067] As shown in FIG. 17 , the protrusion 428 can be configured to include a portion of a ring wall 430 disposed on an inner surface 432 of the side wall 416. A second collar 434 can be positioned within the ring wall 430, and the second collar 434 can define a substantially cylindrical second silo 436 therein. In some cases, the second collar 434 can be positioned asymmetrically relative to the wings 424 a, 424 b on the inner surface 432 of the side wall 416. In some cases, the second collar 434 can be positioned closer toward the wing 424 a than the wing 424 b. Thus, the first collar 392 and the second collar 434 can be offset relative to one another such that the blade 312 is held at an angle relative to the breaker bar 330 within the carriage 310, as described below with reference to FIG. 36 . In some cases, one or more spokes 438 designed to provide structural stability to the cover 366 may be disposed on the inner surface 432 and extend radially between the ring wall 430 and the end wall 422. In other cases, the spokes 438 may be omitted. Additionally, in some cases, one or more expansion members 440 may be provided on the inner surface 442 of the end wall 422 (e.g., to provide positional stability to the blade 312 during use of the cutter assembly 300). For example, two expansion members 440 having a generally curved or parabolic configuration may be disposed on the inner surface 442 adjacent to each of the wings 424a, 424b. In other cases, the expansion members 440 may be omitted.

[0068] 18 and 19 , the blade 312 may be provided in the form of a substantially circular body 444 defined by a cutting edge 446. The mounting hole 448 may be provided in the form of a circular opening extending through the body 444 and may be centered relative to the cutting edge 446. In some cases, the blade 312 may include one or more auxiliary holes 450 (e.g., to reduce the weight of the blade 312, aid in heat dissipation, improve cost-effectiveness, etc.). In other cases, the auxiliary holes 450 may be omitted. The body 444 may be provided in the form of carbon steel, stainless steel, alloy steel, cast iron, wrought iron, or any other suitable material. Additionally, in some cases, the blade 312 may be subjected to a through-hardening process designed to increase the hardness of its entire body 444. In other cases, blade 312 may receive any case hardening process or any other process known in the art for hardening steel or other metals (e.g., nitriding, carburizing, nitrocarburizing, powder coating, etc.).

[0069] The blade 312 has a diameter D measured between two points positioned diametrically opposite each other along the cutting edge 446. B The diameter D can be determined by B can be given a value of about 12 millimeters (mm) to about 30 mm (or 12 mm to 30 mm) or about 20 mm to about 30 mm (or 20 mm to 30 mm). For example, the diameter D B can be given a value of at least about 12 mm (or at least 12 mm), at least about 14 mm (or at least 14 mm), at least about 16 mm (or at least 16 mm), at least about 18 mm (or at least 18 mm), at least about 20 mm (or at least 20 mm), at least about 22 mm (or at least 22 mm), at least about 24 mm (or at least 24 mm), at least about 26 mm (or at least 26 mm), at least about 28 mm (or at least 28 mm), or at least about 30 mm (or at least 30 mm). In some cases, the diameter DB can be given a value of approximately 25.4 mm (or 25.4 mm).

[0070] 19 , the blade 312 can be positioned between a screw member 452 abutting a first side 454 of the blade 312 and a nut member 456 abutting a second side 458 of the blade 312. A washer 460 can be positioned adjacent to the screw member 452 and on the opposite side of the blade 312 relative to the screw member 452. A spring 462 can be positioned adjacent to the washer 460 and on the opposite side of the screw member 452 relative to the washer 460. The blade 312, screw member 452, nut member 456, washer 460, and spring 462 can be coaxially arranged such that a rod 464 can extend linearly through them.

[0071] 20 , the threaded member 452 can be provided in the form of a tubular body 466 defined by a first end 468 and a second end 470. A polygonal first cuff 472 can be positioned between the first end 468 and the second end 470 and surrounds the body 466. In some cases, the first cuff 472 can be hexagonal in shape. In other cases, the first cuff 472 can have any suitable shape. The body 466 can include a threaded segment 474 positioned proximate the first end 468. The body 466 can define a substantially cylindrical first conduit 476 extending completely therethrough (e.g., extending between the first end 468 and the second end 470). The first conduit 476 can be configured to receive the rod 464. In some cases, the first conduit 476 can be provided with substantially the same structure as the rod 464 .

[0072] As best shown in FIG. 21 , the nut member 456 can be provided in the form of a tubular body 478 defined by a first end 480 and a second end 482. The body 478 of the nut member 456 can be substantially cylindrical in shape, except that a polygonal second cuff 484 can be positioned at the second end 482 and can surround the body 478. In some cases, the second cuff 484 can be identical or substantially identical to the first cuff 472. For example, each of the first and second cuffs 472, 484 can be substantially hexagonal in shape. In other cases, the first cuff 472 and the second cuff 484 can be identical and can be given any other suitable shape, or the first cuff 472 and the second cuff 484 can be provided in different forms. The body 478 may further define a substantially cylindrical second conduit 486 extending completely therethrough (e.g., extending between the first end 480 and the second end 482). In some cases, at least a portion of the inner surface 488 defining the second conduit 486 may be threaded configured to receive and engage the threaded segment 474 of the threaded member 452.

[0073] 22, together, the screw member 452 and the nut member 456 can define a hub 489 designed to support and / or retain the blade 312. The hub 489 has a total hub length L measured linearly between the second end 470 of the screw member 452 and the first end 480 of the nut member 456. H In some cases, the hub length L H can be given a value of about 5 mm to about 30 mm (or 5 mm to 30 mm) or about 10 mm to about 20 mm (or 10 mm to 20 mm). For example, the hub length L Hcan be given a value of at least about 5 mm (or at least 5 mm), at least about 10 mm (or at least 10 mm), at least about 15 mm (or at least 15 mm), at least about 20 mm (or at least 20 mm), at least about 25 mm (or at least 25 mm), or at least about 30 mm (or at least 30 mm). In some cases, the hub length L H can be given a value of approximately 13.3 mm.

[0074] In some cases, the diameter D of the blade 312 B and hub length L H The ratio between (i.e., D B / L H ) can be smaller than 2.0. For example, the diameter D of the blade 312 B and hub length L H For example, the ratio between the diameter D of the blade 312 and the diameter D of the blade 312 may be about 1.9. B and hub length L H In other cases, the ratio between the diameter D of the blade 312 and the diameter D of the blade 312 may be greater than about 2.0. B and hub length L H can be about 0.4 to about 6 (or 0.4 to 6), about 0.4 to about 2.4 (or 0.4 to 2.4), about 0.4 to less than 2.0 (or 0.4 to less than 2.0), about 0.4 to about 1.9 (or 0.4 to 1.9), about 1 to about 1.9 (or 1 to 1.9), about 1.5 to about 1.9 (or 1.5 to 1.9), or about 1.8 to about 1.9 (or 1.8 to 1.9).

[0075] As best shown in FIG. 23 , the first end 468 of the screw member 452 can be inserted through the mounting hole 448 of the blade 312 and into the second conduit 486 of the nut member 456 to seat the blade 312 on the hub 489 between the first cuff 472 and the second cuff 484. Thus, engagement between the threaded segment 474 and the threaded inner surface 488 (or the threaded portion of the inner surface 488) can couple the screw member 452 to the nut member 456 with the blade 312 disposed therebetween. Thereafter, as best shown in FIG. 24 , the rod 464 can be inserted into the first conduit 476 and extended completely therethrough. Thus, the rod 464 can extend through (forming its central axis) the screw member 452, the nut member 456, and the blade 312 such that its first end 490 can be substantially flush or coplanar with the first end 480 of the nut member 456 and its second end 492 can extend beyond the second end 470 of the screw member 452. The second end 492 of the rod 464 can then be inserted through the washer 460 and the spring 462 such that the washer 460 is positioned proximate the first cuff 472 of the screw member 452 and the spring 462 is positioned against or adjacent the washer 460 (see FIG. 19 ).

[0076] As can be seen in FIG. 24, the rod 464 has a total rod length L measured linearly between its first end 490 and second end 492. R In some cases, the rod length L R can be given a value of about 10 mm to about 40 mm (or 10 mm to 40 mm), or about 15 mm to about 25 mm (or 15 mm to 25 mm). For example, the rod length L R can be given a value of at least about 10 mm (or at least 10 mm), at least about 15 mm (or at least 15 mm), or at least about 20 mm (or at least 20 mm). In some cases, the rod length L R can be given a value of about 20 mm (or 20 mm).

[0077] In some cases, the diameter D of the blade 312 B and rod length L R The ratio between (i.e., D B / L R ) can be smaller than 2.0. For example, the diameter D of the blade 312 B and rod length L R In other cases, the ratio between the diameter D of the blade 312 and the B and rod length L R In other cases, the ratio between the diameter D of the blade 312 and the B and rod length L R can be about 0.3 to about 3 (or 0.3 to 3), about 0.3 to about 2 (or 0.3 to 2), about 0.3 to less than 2.0 (or 0.3 to less than 2.0), about 0.3 to about 1.9 (or 0.3 to 1.9), about 0.75 to about 1.9 (or 0.75 to 1.9), about 1 to about 1.9 (or 1 to 1.9), about 1 to about 1.5 (or 1 to 1.5), about 1 to about 1.3 (or 1 to 1.3), or about 1.2 to about 1.3 (or 1.2 to 1.3).

[0078] 25, the first end 480 of the nut member 456 and the rod 464 can be aligned with the first collar 392 such that the first silo 396 receives the first end 490 of the rod 464 to install the blade 312 within the carrier 364. The cover 366 can then be coupled to the carrier 364 with the fastener 368 (see FIG. 12). The cover openings 426a, 462b can be aligned with the carrier openings 390a, 390b such that the fastener 368 can be inserted through and securely received by the cover openings 426a, 462b in the cover 366 and the carrier openings 390a, 390b in the carrier 364. Due to the alignment of the cover openings 426a, 462b with the carrier openings 390a, 390b, the second collar 434 can be positioned so that the second silo 436 can receive the second end 492 of the rod 464. That is, due to the offset between the first collar 392 and the second collar 434, the rod 464 can be securely positioned or suspended at an angle between the first silo 396 and the second silo 436. In this manner, the carrier 364 and cover 366 can hold the blade 312 at an angle within the carriage 310.

[0079] Furthermore, when the carriage 310 is assembled to hold the blade 312, at least a portion of the spring 462 proximate the second end 492 of the rod 464 can be received by the ring wall 430 of the cover 366. In this manner, the spring 462 can provide stability to the blade 312 and / or other components of the blade subassembly 304 by applying a stabilizing force to the washer 460. The carriage 310 can be configured to hold the blade 312 at a fixed angle within the carriage 310, regardless of whether the cutter assembly 300 is in use.

[0080] 26 , the guide rail 314 may be provided in the form of a linear body 494 defined by a first side 496 and an opposing second side 498. One or more openings 500 configured to facilitate attachment of the guide rail 314 to the frame 302 may be formed in and extend completely through the body 494. For example, the body 494 may include two openings 500 proximate the first side 496 and two openings 500 proximate the second side 498.

[0081] 27 , the body 494 may include a rear wall 502 having a top end 504 and a bottom end 506. The body 494 may further include an upper lip 508 extending outward from the top end 504 of the rear wall 502 and terminating at a distal end 510, and a lower lip 512 extending outward from the bottom end 506 of the rear wall 502 and terminating at a distal end 514. The upper and lower lips 508, 512 may be oriented substantially perpendicular to the rear wall 502. A rail member 516 configured to engage the runner 372 of the carrier 364 and extending at least partially between the first side 496 and the second side 498 of the body 494 may be positioned on each of the upper and lower lips 508, 512. For example, a first rail member 516a may be disposed along the upper lip 508 and extend downwardly therefrom (e.g., toward the lower lip 512). A second rail member 516b may be disposed along the lower lip 512 and extend upwardly therefrom (e.g., toward the upper lip 508). In this manner, the rail members 516 may define a track 518 along which the runner 372 may move laterally relative to the guide rail 314.

[0082] 28 , the carrier 364 can be slidably coupled to or mounted along the guide rail 314 through a runner 372. For example, the angle members 374 a, 374 b can occupy a track 518 defined by a rail member 516 of the guide rail 314. In particular, a point 378 a of the first angle member 374 a can be positioned between the first rail member 516 a and the rear wall 502 of the guide rail 314. Similarly, a point 378 b of the second angle member can be positioned between the second rail member 516 b and the rear wall 502 of the guide rail 314. Thus, engagement between the runner 372 and the rail member 516 can hold the carriage 310 by the guide rail 314. In this manner, the blade subassembly 304 can be configured to undergo translational movement between the first side 496 and the second side 498 of the guide rail 314 (see FIG. 29 ). As shown in FIG. 29, the appendages 406 can be oriented parallel to the guide rail 314 and can rest against the first rail member 516a (e.g., the vertical wall 408 of each appendage 406 can be in contact with or substantially flush with the first rail member 516a).

[0083] 30-32 , the guide rail 314 may be coupled to the frame 302 by one or more fasteners 520. The fasteners 520 may be provided in the same or different form as the fasteners 368 used to assemble the carriage 310. Openings 500 adjacent the first and second sides 496, 498 of the body 494 of the guide rail 314 may align with mounting holes 354 positioned on the first and second tabs 356 a, 356 b, respectively, of the frame 302. Thus, the fasteners 520 may extend through each of the body 494 of the guide rail 314 and the tabs 356 a, 356 b of the frame 302 and be securely received by one or both of the openings 500 and the mounting holes 354 (e.g., through engagement between complementary threaded surfaces thereof, through a press fit, or through any other suitable mechanism known in the art).

[0084] The rear wall 502 of the guide rail 314 can be disposed behind the frame 302 (e.g., adjacent the rear face 522 opposite the front face 361 of the frame 302). Thus, the fastener 520 can first penetrate the rear wall 502 and then extend through the rear face 522 of the frame 302. The guide rail 314 can be positioned between the top end 350 and the bottom end 352 of the entrance 344 and can extend linearly between the first side 346 and the second side 348 of the entrance 344 (e.g., between tabs 356a and 356b). As best seen in FIG. 32 , the guide rail 314 and blade subassembly 304 can be configured such that the upper lip 508 of the guide rail extends beyond the front face 361 of the frame 302 and the blade subassembly is disposed either partially or fully in front of the front face 361 (e.g., on the opposite side of the rear face 522 from the body 334).

[0085] Turning to FIG. 33 , the support rail 524, designed to provide structural rigidity and / or stability to the guide rail 314, frame 302, and / or other components of the cutter assembly 300, may be provided in the form of a rectilinear body 526 defined by a first side 528 and an opposing second side 530. The body 526 may include a rear wall 532, an upper lip 534, and a lower lip 536, each of which may extend between the first side 528 and the second side 530. The rear wall 532 may be provided in the form of a substantially rectangular panel. The upper and lower lips 534, 536 may be connected to opposite ends 538, 540 of the rear wall 532 and extend outwardly therefrom. For example, each of the upper and lower lips 534, 536 may be provided in the form of a substantially rectangular panel oriented substantially perpendicular to the rear wall 532. One or more racetrack-shaped openings 542 may extend through the rear wall 532, and the openings 542 may be spaced apart between the first side 528 and the second side 530 of the body 526 and between the opposite ends 538 and 540 of the rear wall 532.

[0086] As best shown in FIG. 35 , the support rail 524 can be coupled to the front surface 361 of the frame 302 by one or more fasteners 544 and can be positioned proximate the upper end 350 of the entrance 344. For example, the opening 542 in the rear wall 532 of the support rail 524 can be aligned with one or more mounting holes 354 proximate the upper end 350 of the entrance 344. Thus, the fasteners 544 can extend through each of the rear wall 532 of the support rail 524 and the frame 302 and be securely received by one or both of the openings 542 and the mounting holes 354 (e.g., through engagement between their complementary threaded surfaces, through a press fit, or through any other suitable mechanism known in the art). The fasteners 544 can be provided in the same or a different form as the fasteners 520 used to couple the guide rail 314 to the frame 302. In some cases, the support rail 524 may be centered relative to and extend at least partially linearly between the first and second sides 346, 348 of the entrance 344. The lower lip 536 of the support rail 524 may be adjacent to or directly abut the upper lip 508 of the guide rail 314.

[0087] 34 , the crusher bar 330 can be provided in the form of a linear body 546 defined by a first side 548 and an opposing second side 550. The body 546 can include a chamfered edge 552 and a trailing edge 554, each extending linearly between the first side 548 and the second side 550. One or more openings 556 can extend through the body 546, and the openings 556 can be positioned along the body 546 between the first side 548 and the second side 550. In some cases, the crusher bar 330 can be configured to be coupled to and / or supported by a ledge 358 of the frame 302. The crusher bar 330 can be oriented substantially parallel to the guide rails 314 when the cutter assembly 300 is assembled. In some cases, the breaker bar 330 can be provided in the form of nitrided stainless steel (e.g., 300 series stainless steel). In other cases, the breaker bar 330 can be provided in the form of other classifications or types of steel or other magnetic or non-magnetic metals. In still other cases, the breaker bar 330 can further comprise ceramic, anodized aluminum, or any other material having a suitable hardness. The breaker bar 330 is preferably non-magnetic so that the breaker bar 330 can print without interference as magnetic media passes through a printer (e.g., printer 100, 160, 210, or any other suitable printing device). Additionally, in some cases, the breaker bar 330 can undergo a through-hardening process designed to increase the hardness of its entire body 546. In other cases, the breaker bar 330 may receive any case hardening process or any other process known in the art for hardening steel or other metals (e.g., nitriding, carburizing, nitrocarburizing, powder coating, etc.).

[0088] The crusher bar 330 may be provided with a hardness of greater than 40 Hardness Rockwell C (HRC). In some cases, the crusher bar 330 may be provided with a hardness of about 40 HRC to about 80 HRC (or 40 HRC to 80 HRC) or about 40 HRC to about 60 HRC (or 40 HRC to 60 HRC). For example, the crusher bar 330 may be provided with a hardness of at least about 40 HRC (or at least 40 HRC), at least about 50 HRC (or at least 50 HRC), at least about 60 HRC (or at least 60 HRC), at least about 70 HRC (or at least 70 HRC), or at least about 80 HRC (or at least 80 HRC). In some cases, the crusher bar 330 may be provided with a hardness of about 50 HRC (or 50 HRC). In some cases, the blades 312 may be provided with a hardness substantially equal to the hardness of the disrupter bars 330 .

[0089] 35 , the crusher bar 330 can be positioned on a ledge 358 of the frame 302 and can be coupled to the ledge 358 by one or more fasteners 558. For example, an opening 556 disposed along the body 546 of the crusher bar 330 can align with one or more mounting holes 354 disposed along the ledge 358 of the frame 302. Thus, the fastener 558 can extend through each of the body 546 of the crusher bar 330 and the ledge 358 of the frame 302 and can be securely received by one or both of the opening 556 and the mounting hole 354 (e.g., through engagement between their complementary threaded surfaces, through a press fit, or through any other suitable mechanism known in the art). At least a portion of the crusher bar 330, including the chamfered edge 552, can extend beyond the ledge 358 of the frame 302.

[0090] 36, the blades 312 can be oriented at a first angle A1 relative to the chamfered edge 552 of the breaker bar. The first angle A1 can have a value of about 0.5° to about 5° (or 0.5° to 5°), about 0.5° to about 3° (or 0.5° to 3°), about 1° to about 2° (or 1° to 2°), about 1.5° to about 2° (or 1.5° to 2°), or about 1° to about 1.5° (or 1° to 1.5°). For example, the first angle A1 can be given a value of at least about 0.5° (or at least 0.5°), at least about 1° (or at least 1°), at least about 1.5° (or at least 1.5°), at least about 2° (or at least 2°), at least about 2.5° (or at least 2.5°), at least about 3° (or at least 3°), at least about 3.5° (or at least 3.5°), at least about 4° (or at least 4°), at least about 4.5° (or at least 4.5°), or at least about 5° (or at least 5°). In some cases, the first angle A1 can be given a value of about 1.5° (or 1.5°).

[0091] 37, the cutting edge 446 of the blade 312 can be defined by a second angle A2. The second angle A2 can have a value of about 10° to about 90° (or 10° to 90°), about 20° to about 80° (or 20° to 80°), about 30° to about 70° (or 30° to 70°), about 40° to about 60° (or 40° to 60°), about 30° to about 45° (or 30° to 45°), or about 45° to about 60° (or 45° to 60°). For example, the second angle A2 can be at least about 10° (or at least 10°), at least about 20° (or at least 20°), at least about 30° (or at least 30°), at least about 40° (or at least 40°), at least about 50° (or at least 50°), at least about 60° (or at least 60°), at least about 70° (or at least 70°), at least about 80° (or at least 80°), or at least about 90° (or at least 90°). In some cases, the second angle A2 can be at least about 45° (or 45°). In some cases, the second angle A2 can be at least 40° to 50°.

[0092] The chamfered edge 552 of the breaker bar 330 can be defined by a third angle A3. The third angle A3 can have a value of about 25° to about 90° (or 25° to 90°), about 30° to about 90° (or 30° to 90°), about 40° to about 90° (or 40° to 90°), about 50° to about 90° (or 50° to 90°), about 60° to about 90° (or 60° to 90°), about 70° to about 90° (or 70° to 90°), about 80° to about 90° (or 80° to 90°), or about 70° to about 80° (or 70° to 80°). For example, the third angle A3 can be at least about 25° (or at least 25°), at least about 40° (or at least 40°), at least about 50° (or at least 50°), at least about 60° (or at least 60°), at least about 70° (or at least 70°), at least about 80° (or at least 80°), or at least about 90° (or at least 90°). In some cases, the third angle A3 can be at about 80° (or 80°). In some cases, the third angle A3 can be at a value between 75° and 80°.

[0093] In some cases, (i) the first angle A1 can be assigned a value of 0.5° to 5°, 0.5° to 3°, 1° to 2°, 1.5° to 2°, 1° to 1.5°, or 1.5°; (ii) the second angle A2 can be assigned a value of 10° to 90°, 20° to 80°, 30° to 70°, 40° to 60°, 30° to 45°, 45° to 60°, 40° to 50°, or 45°; and (iii) the third angle A3 can be assigned a value of 25° to 90°, 30° to 90°, 40° to 90°, 50° to 90°, 60° to 90°, 70° to 90°, 80° to 90°, 70° to 80°, 75° to 80, or 80°. In some cases, (i) the breaker bar 330 can have a hardness of 40 HRC to 80 HRC, 40 HRC to 60 HRC, or 50 HRC, and (ii) the blades 312 can have a hardness of 40 HRC to 80 HRC, 40 HRC to 60 HRC, or 50 HRC. In some cases, the breaker bar 330 is a non-magnetic breaker bar.

[0094] That is, the chamfered edge 552 of the breaker bar 330 can be configured to provide a single point of contact 560 with the blade 312 as the blade subassembly 304 moves laterally along the guide rail 314. The single point of contact 560 aids in the operation of the cutter assembly 300 by creating a high stress point in the material being cut. In instances where the blade 312 may be prone to buildup (e.g., buildup of adhesive material resulting from cutting adhesive labels, etc.), the angle A1, angle A2, angle A3, and / or the single point of contact 560 can reduce the amount of buildup over the life of the cutter assembly 300.

[0095] As best shown in FIG. 37, the blade 312 has a thickness T measured linearly between its first side 454 and second side 458. B In some cases, the thickness T B can be given a value of about 0.2 mm to about 1 mm (or 0.2 mm to 1 mm) or about 0.2 mm to about 0.8 mm (or 0.2 mm to 0.8 mm). For example, the thickness TB can be given a value of at least about 0.2 mm (or at least 0.2 mm), at least about 0.3 mm (or at least 0.3 mm), at least about 0.4 mm (or at least 0.4 mm), at least about 0.5 mm (or at least 0.5 mm), at least about 0.6 mm (or at least 0.6 mm), at least about 0.7 mm (or at least 0.7 mm), at least about 0.8 mm (or at least 0.8 mm), at least about 0.9 mm (or at least 0.9 mm), or at least about 1 mm (or at least 1 mm). B can be given a value of 0.5 mm.

[0096] In some cases, the diameter D of the blade 312 B can be given a value of 12 mm to 30 mm, 20 mm to 30 mm, or 25.4 mm; (ii) thickness T B may be assigned a value of 0.2 mm to 1 mm, 0.2 mm to 0.8 mm, or 0.5 mm. In some cases, (i)D B / L H the ratio is 0.4 to 6, 0.4 to 2.4, 0.4 to less than 2.0, 0.4 to 1.9, 1 to 1.9, 1.5 to 1.9, 1.8 to 1.9, or 1.9; (ii) D B / L R ) ratio is 0.3 to 3, 0.3 to 2, 0.3 to less than 2.0, 0.3 to 1.9, 0.75 to 1.9, 1 to 1.9, 1 to 1.5, 1 to 1.3, 1.2 to 1.3, or 1.3.

[0097] Turning now to FIG. 38 , the pulley subassembly 306 can be designed to generate translational movement of the blade subassembly 304 along the guide rail 314. The belt 316 can surround and engage multiple pulleys 321. In some cases, the pulley subassembly 306 can include five pulleys 321 a-e. In other cases, any number of pulleys 321 can be provided and can include any suitable arrangement. In some cases, rotation of the compound gear 320 can cause rotation of the first pulley 321 a (see FIG. 40 ) connected thereto, which can in turn cause responsive rotation of the pulleys 321 b-e. A carrier 364 can be coupled to an active portion 562 of the belt 316 positioned between the second pulley 321 b and the third pulley 321 c.

[0098] Turning to FIG. 39 , each pulley 321 can be provided in the form of two opposing substantially annular flanges 564, each defined by an outer periphery 566, and a substantially annular notched wheel 568 positioned therebetween. The flanges 564 and the notched wheel 568 can be coaxial with one another such that a substantially cylindrical opening 570 extends therethrough. A plurality of notches 572 (e.g., provided in a configuration substantially the same as or complementary to the notches 414 of the carrier 364) configured to receive or otherwise engage the belt 316 can be circumferentially circumferentially spaced apart from one another. Each pulley 321 can thus be configured to convert its rotational motion into translational or linear motion of the belt 316. In some cases, each of the five pulleys 321a-321e can be provided with the above-described structure. In other cases, the pulley subassembly 306 may include any number of pulleys 321 having any suitable shape or configuration, so long as the pulleys 321 are configured to drive the movement of the belt 316 .

A first plurality of teeth 578 can circumscribe the outer periphery 576 and can be evenly radially spaced apart from one another. A first pulley 321 a can be connected to the body 574 of the compound gear 320 and extend outwardly therefrom. The first pulley 321 a can be integrally formed with or coupled to the body 574. The first pulley 321 a and the body 574 can be coaxial with one another, such that the opening 570 can extend completely through both the compound gear 320 and the first pulley 321 a. In some cases, the compound gear 320 can be configured to increase the gear ratio from the motor 322 to the pulleys 321 a-321 e.

A mounting region 590 configured to receive the pulley 321 can be positioned between the disk member 586 and the groove 588. In some cases, the mounting region 590 can be provided with substantially the same dimensions as the opening 570 in the pulley 321.

[0101] 42 , washer 592, which is designed to reduce or more evenly distribute stresses applied to pulley 321 or other components of pulley subassembly 306, may be provided in the form of a substantially annular disk 594 defined by an inner diameter 596 and an outer diameter 598. An entry slot 600, which allows washer 592 to be seated on groove 588, may be provided in the form of an opening extending between a portion of inner diameter 596 and a portion of outer diameter 598 adjacent to that portion. Additionally, washer 592 may include one or more flared notches 602 disposed along inner diameter 596 and extending partially between inner diameter 596 and outer diameter 598.

[0102] 43 , a tensioner pin 604 designed to couple one or more of the pulleys 321 to the frame 302 can be provided in the form of a substantially tubular body defined by a first end 606 and an opposing second end 608. The tensioner pin 604 can include a cylindrical insert 610 at the first end 606, a circular button 612 at the second end 608, and a mounting area 614 positioned between the ends and configured to receive the pulley 321. In some cases, the mounting area 614 can be provided with substantially the same dimensions as the opening 570 in the pulley 321.

[0103] 44 , a belt tensioner 616 configured to facilitate mounting one or more pulleys 321 on the frame 302 can be provided in the form of a body 618 defined by a top end 620 and a bottom end 622. The body 618 can include an upper segment 624 proximate the top end 620, a lower segment 626 proximate the bottom end 622, and a connector 628 extending between the segments (e.g., joining or connecting the upper segment 624 and the lower segment 626). Each of the upper and lower segments 624, 626 can be substantially vertical (parallel to the body 334 of the frame 302), and the connector 628 can extend substantially perpendicular to the upper and lower segments 624, 626. The upper segment 624 can include a pulley bore 630 positioned proximate the top end 620 and configured to receive the insert 610 of the tensioner pin 604. Lower segment 626 may include a mounting hole 632 proximate connector 628 and a curved opening 634 positioned between mounting hole 632 and bottom end 622. Lower segment 626 may further include an anchor 636 disposed at bottom end 622 and extending outwardly therefrom (e.g., in a direction substantially parallel to connector 628).

[0104] 45 , the belt 316 can be provided in the form of an elongated body 638 defined by an outer surface 640 and an inner surface 642. A plurality of rounded ridges 644 project upwardly from the inner surface 642 and are configured to be received by the notches 414 of the carrier 364 and the notches 572 of the pulley 321. The ridges 644 can be disposed along the inner surface 642 of the belt 316 and evenly spaced apart from one another. In some cases, the ridges 644 can be substantially semi-cylindrical in shape. However, in other cases, the ridges 644 can have any suitable shape or configuration, so long as the ridges 644 are configured to engage the notches 414, 572.

[0105] As best shown in FIG. 46 , the motor 322 may be provided in the form of a substantially cylindrical body 646 having a front side 648, an opposing rear side 650, and a substantially cylindrical sidewall 652 extending therebetween. A cylindrical pin member 654 may extend outwardly from the front side 648 of the motor 322 and connect to or communicate with the motor 322. In some cases, the motor 322 may be configured to drive rotation of the pin member 654. The motor 322 may further include one or more contacts 656 disposed on and extending outwardly from the rear side 650 and configured to connect the motor 322 to an external power source (not shown). In some cases, the motor 322 may be provided in the form of a standard direct current (DC) motor. In other cases, the motor 322 may be provided in the form of an alternating current (AC) motor, a stepper motor, a servo motor, or any other suitable device.

[0106] 47 , the drive gear 318 may be provided in the form of an annular body 658 defined by an inner diameter 660 and an outer diameter 662. A second plurality of teeth 664 may extend outwardly from the body 658 and be evenly spaced radially around the outer diameter 662. The second plurality of teeth 664 may be configured to engage the first plurality of teeth of the compound gear 320. The inner diameter 660 may define a cylindrical opening 666 therethrough, which may be configured to receive the pin member 654 of the motor 322.

[0107] The pulley subassembly 306 can be positioned for installation on the frame 302 as shown in FIGS. 48 and 49. A mounting area 590 of the first frame pin 580a can be retained within an opening 570 extending through the compound gear 320 and the first pulley 321a. A first end 582 of the first frame pin 580a can be configured to extend outward from the first pulley 321a and be received by one of the mounting holes 354 in the frame 302, thereby coupling the compound gear 320 and the first pulley 321a to the frame 302 (see FIG. 49). The second, third, and fifth pulleys 321b, 321c, and 321e can each receive the second, third, and fourth frame pins 580b, 580c, and 580e, respectively. The second, third, and fourth frame pins 580b, 580c, 580e can facilitate coupling between the second, third, and fifth pulleys 321b, 321c, 321e and the frame 302 in the same manner as the first frame pin 580a. The mounting area 614 of the tensioner pin 604 can be received by the opening 570 of the fourth pulley 321d. The insert 610 of the tensioner pin 604 can be received by the pulley bore 630 of the belt tensioner 616 such that the fourth pulley 321d is captured between the button 612 of the tensioner pin 604 and the upper segment 624 of the belt tensioner 616.

[0108] The belt 316 can surround one or more of the pulleys 321 such that the ridges 644 of the belt 316 engage the notches 572 of the pulleys 321. In some cases, the belt 316 can be configured such that the fifth pulley 321e engages the outer surface 640 of the belt 316 rather than the ridges 644 on the inner surface 642. In this manner, the fifth pulley 321e can be configured to cause an outward (clockwise as viewed from the perspective of FIG. 48) turn of the belt 316, whereas each of the first, second, third, and fourth pulleys 321a-321d can be configured to cause an inward (counterclockwise as viewed from the perspective of FIG. 37) turn of the belt 316. That is, the fifth pulley 321e can be positioned to deflect the belt 316 so that the first pulley 321 can engage the belt 316 rather than directly driving the movement of the belt 316.

[0109] In some cases, the motor 322 can be positioned proximate to the compound gear 320 such that the pin member 654 is positioned proximate to the first plurality of teeth 578 of the compound gear 320 and extends in a direction substantially parallel to the common axis of rotation of the compound gear 320 and the first pulley 321 a. The drive gear 318 can receive the pin member 654 of the motor 322 through the opening 666, and the drive gear 318 can be coupled to the opening 666 (e.g., by adhesive, press fit, or any other suitable mechanism known in the art) such that the pin member 654 and the drive gear 318 are configured to rotate in unison. The second plurality of teeth 664 of the drive gear 318 can be received by and engage with the first plurality of teeth 578 of the compound gear 320. Thus, motor 322 can be configured to drive rotation of the drive gear, thereby causing rotation of compound gear 320 and causing movement of belt 316 around pulleys 321 a, 321 b, 321 c, 321 d. Motor 322 can be configured to generate bidirectional rotation of pin member 654. Thus, motor 322 can be configured to drive movement of belt 316 in either a first direction or an opposite second direction.

[0110] In other cases, the drive gear 318 and the compound gear 320 can be omitted. In these cases, the motor 322 can be configured to directly engage the pulleys 321. For example, the motor 322 can be configured so that the pin member 654 is received by the first pulley 321a rather than the drive gear 318 and causes bidirectional rotation thereof. Alternatively, the motor 322 can include any other suitable method, so long as it is configured to generate bidirectional rotation of at least one pulley 321. Thus, the motor 322 can be arranged to drive movement of the belt 316 around the multiple pulleys 321 without the use of gears.

[0111] As best shown in FIG. 49 , washers 592 can be installed in grooves 588 of the first, second, third, and fourth frame pins 580a-580d. The belt tensioner 616 can be coupled to the frame 302 through a fastener 668 that extends through its mounting hole 632 and the adjacent mounting hole 354 in the frame 302. Another fastener 668 can extend through a curved opening 634 in the belt tensioner 616 and the adjacent mounting hole 354 in the frame 302, thereby coupling the lower segment 626 of the belt tensioner 616 to the frame 302. In some cases, the fit between the fastener 668 and the curved opening 634 can provide the belt tensioner 616 with some positional flexibility (e.g., the ability to translate or rotate relative to the frame 302). Additionally, the belt tensioner 616 can be configured to provide a desired tension to the belt 316 (eg, to provide tension according to the belt 316 manufacturer's recommendations).

[0112] The spring 670 configured to apply a force to the belt tensioner 616 can include a helical body having a first end 672 and a second end 674. The first end 672 of the spring 670 can be coupled to the anchor 360 of the frame 302, and the second end 674 of the spring 670 can be coupled to the anchor 636 of the belt tensioner 616. The spring 670 can be tensioned to apply a linear force to the lower segment 626 of the belt tensioner 616 in a direction toward the first side 336 of the frame 302. Thus, the spring 670 can be configured to induce rotation of the belt tensioner 616 about the mounting hole 632. In some cases, the spring 670 can be provided to provide an initial tension to the pulley subassembly 306. However, once the belt tensioner 616 is coupled to the frame 302 by the fastener 668 inserted through the mounting hole 632, the tension provided by the spring 670 may no longer be necessary, and the belt tensioner 616 may supply tension solely to the pulley subassembly 306.

[0113] The blade subassembly 304 may be mounted along the active portion 562 of the belt 316 and configured for translational movement between the second pulley 321b and the third pulley 321c. The active portion 562 may be disposed within the gap 379 between the angle members 374a and 374b of the runner 372. Thus, the notch 414 of the notch surface 415 disposed on the second angle member 374 may receive and engage the ridge 644 of the active portion 562 of the belt 316. In this manner, linear movement of the belt 316 driven by the motor 322 may cause translational movement of the carriage 310 along the guide rail 314, thereby causing translational movement of the blade 312 (see FIG. 35).

[0114] Turning now to FIG. 50 , the clamping subassembly 308 may be provided in the form of a clamp 328 and a brace 680 flexibly coupled to the clamp 328 by a substantially cylindrical shaft 682. As best shown in FIGS. 51 and 52 , the clamp 328 may be provided in the form of a substantially linear body 684 defined by a first end 686 and an opposite second end 688. The clamp 328 may be defined by a lower shelf 690, an upper shelf 692 including the deflection tabs 332 a, 332 b, and a substantially linear panel 694 extending between the shelves. The lower shelf 690 may extend outwardly from a bottom edge 696 of the panel 694 and may terminate at a distal end 698 of the lower shelf 690. The lower shelf 690 may be oriented at a downward angle relative to the panel 694 and may include a lip 700 disposed along the distal end 698 and extending therefrom at an upward angle relative to the lower shelf 690. In some cases, the lip 700 may be oriented substantially perpendicular to the panel 694 and may form the portion of the clamp 328 that directly contacts the printable media when the cutter assembly 300 is in use.

[0115] The upper shelf 692 may extend from an upper edge 702 of the panel 694 and may include stepped regions 704 a, 704 b proximate the first end 686 and second end 688, respectively, of the clamp 328. The stepped regions 704 a, 704 b may be provided in the form of linear protrusions oriented substantially perpendicular to the panel 694. Each of the stepped regions 704 a, 704 b may include a deflection tab 332 a, 332 b extending inwardly therefrom and oriented at an upward angle relative to the stepped regions 704 a, 704 b (e.g., the deflection tab 332 a may extend toward the second end 688 and angle away from the lower shelf 690, and the deflection tab 332 b may extend toward the first end 686 and angle away from the lower shelf 690). A substantially rectangular connection region 706 of the upper shelf 692 may extend linearly along the upper edge 702 of the panel 694 between the stepped regions 704a and 704b.

[0116] The body 684 of the clamp 328 may be provided in the form of metal, plastic, a combination thereof, or other suitable composite material. For example, the body 684 may be provided in the form of carbon steel, stainless steel, wrought iron, aluminum, copper, titanium, tin, polycarbonate (PC), acrylonitrile butadiene styrene (ABS), polyvinyl chloride (PVC), polyethylene terephthalate (PET), carbon fiber, fiberglass, or any other suitable material.

[0117] 52 , the panel 694 may include substantially rectangular extension regions 708 a, 708 b positioned adjacent to and oriented substantially perpendicular to the stepped regions 704 a, 704 b, respectively. The panel 694 may further include substantially square or rectangular connection tabs 710 a, 710 b positioned directly below the extension regions 708 a, 708 b and extending rearward therefrom (e.g., extending in a direction opposite to the direction of extension of the stepped regions 704 a, 704 b). Each connection tab 710 a, 710 b may include a substantially circular, oval, or similarly rounded opening 712 a, 712 b extending completely therethrough and configured to receive at least a portion of the shaft 682.

[0118] The clamp 328 may further include a friction member 714 coupled to the lower surface 716 and lip 700 of the lower shelf 690 and positioned to directly contact the media being fed through the cutter assembly 300. The friction member 714 may be provided in the form of a substantially rectangular strip of material selected to provide a high coefficient of friction when in contact with the printable media being severed by the cutter assembly 300. In some cases, the friction member 714 may be provided in the form of a strip of rubber glued or otherwise bonded to the lower surface 716 and lip 700 of the lower shelf 690. In other cases, the friction member 714 may be provided in the form of foam, textured plastic, silicone, felt, microfiber, or any other suitable material.

[0119] 53 , the brace 680 can be provided in the form of a body 718 defined by a first side 720 and a second side 722. The body 718 can include a mounting plate 724 extending between the first side 720 and the second side 722 and a linear fin 726 extending rearward from an upper edge 728 of the mounting plate 724. One or more mounting holes 730 configured to align with one or more mounting holes 354 in the frame 302 can be disposed on and extend completely through the mounting plate 724. The brace 680 can further include connecting arms 734 a, 734 b connected to the mounting plate 724 at the first and second sides 720, 722, respectively, and extending rearward and upward therefrom, terminating at a distal end 733. Slots 736a, 736b in the form of linear or substantially rectangular notches or channels can be disposed at the distal ends 733 of the connecting arms 734a, 734b and extend at least partially downwardly therefrom. The arms 734a, 734b can further include substantially circular openings 738a, 738b positioned proximate the slots 736a, 736b to align with the openings 712a, 712b, respectively, of the connecting tabs 710a, 710b of the clamp 328. In some cases, the openings 738a, 738b can be given substantially the same shape as the shaft 682.

[0120] 54, the shaft 682 can be provided in the form of a substantially cylindrical body 740 defined by a first end 742 and an opposite second end 744. A circular groove 746 can be disposed adjacent each of the first and second ends 742, 744, and each is configured to receive a washer 592 (see FIG. 42). Two spring members 748a, 748b can be disposed along the shaft 682 adjacent the first and second ends 742, 744, respectively. Each of the spring members 748a, 748b may be provided in the form of a spiral body 750, an upper limb 752 extending upward from the spiral body 750 and terminating at a distal end 754 of the upper limb 752, and a lower limb 756 extending downward from the spiral body 750 and terminating at a distal end 758 of the lower limb 756.

[0121] 55 and 56 , the clamp 328 and the brace 680 can be aligned such that they can be coupled to one another through the shaft 682. For example, opening 712a of the clamp 328 and opening 738a of the brace 680 can receive a first end 742 of the shaft 682, and opening 712b of the clamp 328 and opening 738b of the brace 680 can receive a second end 744 of the shaft 682. Spring members 748a, 748b can be disposed along the shaft 682 and positioned adjacent to the arms 734a, 734b such that distal ends 754a, 754b of the upper limbs 752a, 752b can be received by the slots 736a, 736b of the brace 680. In some cases, one or both of the distal ends 758a, 758b of the lower legs 756a, 756b can be connected to another element of the clamping subassembly 308 (e.g., fin 726) or to an adjacent component of the printer in which the cutter assembly 300 is installed. Thus, the spring members 748a, 748b can be configured to apply a consistent downward force to the clamp 328. In some cases, for example, a washer 592 can be installed in the groove 746 of the shaft 682 to prevent disassembly of the clamping subassembly 308 or to reduce the force applied thereto.

[0122] As best shown in FIG. 56 , the shaft 682 can be secured within the openings 738 a, 738 b in the brace 680, while the openings 712 a, 712 b in the clamp 328 can be configured to allow the clamp 328 to move substantially vertically relative to the brace 680. Thus, the carriage 310 can strike either of the deflection tabs 332 a, 332 b (as described above with reference to FIG. 10 ) and cause upward movement of the clamp 328 relative to the brace 680 permitted by the openings 712 a, 712 b. For example, the apex 400 of the carrier 364 can be configured to apply upward pressure to the deflection tabs 332 a, 332 b when the carriage 310 approaches the first and second sides 496, 498, respectively, of the guide rail 314.

[0123] The consistent force applied to the clamp 328 by the spring members 748a, 748b can counteract the upward force applied by the carriage to the deflection tabs 332a, 332b. Thus, the spring members 748a, 748b can bias the clamp 328 to resist upward movement caused by the carriage 310 and return the clamp 328 to a lower position when the carriage 310 is no longer in contact with either of the deflection tabs 332a, 332b. Additionally, the force applied by the spring members 748a, 748b when the carriage 310 is not in contact with either of the deflection tabs 332a, 332b can increase the amount of friction applied by the friction member 714 to the printable medium when the cutter assembly 300 is in use.

[0124] Similarly, the spring members 748a, 748b can be configured to cause a self-cleaning action of the blade 312 whenever the carriage 310 strikes one of the deflection tabs 332a, 332b. In particular, the consistent downward force applied by the spring members 748a, 748b can cause movement of the carriage 310 relative to the breaker bar 330 when the carriage 310 engages one of the deflection tabs 332a, 332b. In some cases, the clamping subassembly 308 can be configured such that the spring members 748a, 748b can move the carriage 310 (and thus the blade 312) substantially downward (e.g., away from the clamp 328) relative to the chamfered edge 552 of the breaker bar 330.

[0125] The relative motion between the blade 312 and the breaker bar 330 allows the blade 312 to "wipe" or deposit onto the breaker bar 330 any buildup that has collected thereon (e.g., adhesive buildup from severing one or more adhesive labels from a continuous supply of adhesive labels). In this manner, buildup can be deposited onto an area of ​​the breaker bar 330 separate from the cutting area (e.g., the area where the cutting edge 446 of the blade 312 contacts the chamfered edge 552 of the breaker bar 330). Due to this action, the clamping subassembly 308 can eliminate or reduce buildup on the blade 312 during use, thereby extending the life of the cutter assembly 300. In some cases, the clamping subassembly 308 can be configured to cause 0.2 mm or more of movement of the blade 312 relative to the breaker bar 330.

[0126] As best shown in FIG. 57 , the brace 680 can be coupled to the frame 302 by one or more fasteners 558. The mounting plate 724 of the brace 680 can be positioned flush with a portion of the frame 302 proximate the bottom end 352 of the inlet 344, such that the mounting holes 730 of the brace 680 align with a corresponding number of mounting holes 354 in the frame 302. Thus, the fasteners 558 can extend through each of the brace 680 and the frame 302 and be securely received by one or both of the mounting holes 730 and the mounting holes 354 (e.g., through engagement between their complementary threaded surfaces, through a press fit, or through any other suitable mechanism known in the art). The clamp 328 may not be directly coupled to the frame 302, except for its engagement with the brace 680 and the shaft 682. The extension regions 708a, 708b can be positioned adjacent the rear wall 502 of the guide rail 314, and the friction member 714 can directly abut the crusher bar 330 when the clamping subassembly 308 is installed on the frame 302.

[0127] 58A-58C, a method of severing a portion of printable media using the cutter assembly 300 is shown. First, a desired portion 760 of a supply 762 of printable media is fed through the cutter assembly 300 from the entrance 344 (not shown). The blade subassembly 304 can occupy a default position (shown in FIGS. 58A and 58B) adjacent the second side 338 of the frame 302. The carrier 364 can be configured to engage the deflection tab 332b when the blade subassembly 304 is in the default position, thereby lifting the clamp 328. In this manner, the friction member 714 can be maintained at a distance from the breaker bar 330 and prevented from impeding the movement of the desired portion 760 of the supply 762 of printable media through the entrance 344.

[0128] Second, the motor 322 can be activated, and the pulley subassembly 306 can initiate a cut by moving the blade subassembly 304 away from the default position and linearly across the guide rail 314 in the direction of arrow 764 in FIG. 58B (e.g., toward the first end 548 of the breaker bar 330). As the carriage 310 moves away from the second end 550 of the breaker bar 330, the carriage 310 can disengage from the deflector tab 332b (e.g., the apex 400 no longer contacts the deflector tab 332b), and the clamping subassembly 308 can lower the clamp 328 toward the breaker bar 330. In this manner, the friction member 714 can contact the supply 762 of printable media and stabilize it against the breaker bar (e.g., to prevent movement of the supply and / or desired portion 760 during cutting). The carriage 310 can carry the blade 312 along the chamfered edge 552 from the second side 550 to the first side 548 of the breaker bar 330 to sever the desired portion 760 from the supply 762 of printable media.

[0129] The severing phase can end when the blade subassembly 304 approaches the first end 548 of the breaker bar 330, causing at least a portion of the blade subassembly 304 (e.g., appendage 406) to contact the trigger 326a and cause the switch 324a to stop the motor 322. Before (or simultaneously with) the carriage 310 contacting the trigger 326a, the carriage 310 can engage the deflector tab 332a (e.g., by contact between the deflector tab 332a and the apex 400). Thus, as the carriage 310 approaches the first end 548 of the breaker bar 330, the clamp 328 can be lifted off the breaker bar 330, thereby releasing the printable media supply 762. When the carriage reaches the first end 548 of the breaker bar 330, the desired portion 760 can be completely severed from the printable media supply 762 and removed, for example, by a user.

[0130] At the same time, clamp 328 can initiate a self-cleaning action of blade 312 by applying an opposing downward force on blade subassembly 304 as carriage 310 engages and lifts clamp 328 (as described above with reference to FIG. 56 ). In instances where the supply 762 of printable media is provided in the form of, for example, strips of adhesive labels, the self-cleaning action of blade 312 can displace buildup of adhesive material from the cuts from blade 312 to breaker bar 330 where it cannot or is unlikely to interfere with subsequent cuts.

[0131] Third, the printer (not shown) can at least partially retract the printable media supply 762 into the printer (away from the inlet 344). Fourth, the pulley subassembly 306 can transport the blade subassembly 304 back to its default position, away from the first end 548 of the breaker bar 330, without affecting or otherwise being obstructed by the printable media supply 762. The blade subassembly 304 reaches its default position when the carriage 310 contacts the trigger 326b, thereby causing the switch 324b to stop the motor 322 and stop movement of the carriage 310. When the blade subassembly 304 returns to its default position, the blade 312 can undergo another automatic cleaning action initiated by contact between the carriage 310 and the deflector tab 332b.
