Abstract

To provide a material holder for being used for a printer.SOLUTION: A material holder for being used for a printer is provided. The material holder can capture a roll of a printable medium (for example, a roll of printable adhesive label fixed to a liner) having a variety of width. In one example, the material holder can contain: two flanges; a spindle having an arm and a key hole region; and a side surface clip. The flanges can perform positioning along the arm of the spindle by having a proper distance for receiving the roll of a desirable printable medium between them. A medium roll is sandwiched between the two flanges, and can be constituted so as to rotate around the arm of the spindle. The side surface clip can be connected to the arm of the spindle, and following or other unintended movements can be prevented.SELECTED DRAWING: Figure 1

Description

[Technical Field]

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

[0002] Printers designed to print images, text, or other graphics onto various forms of printable media (e.g., labels, signs, stickers, tags, magnets, rolls of paper, plastic, or other materials, etc.) typically use material holders to hold and dispense printable media rolls when the printer is in use. In most cases, these material holders include side flanges that sandwich the roll of printable media from either side to keep it in place. However, these side flanges often have a circular or similar rounded shape that can make the material holder susceptible to accidental rolling or dropping when placed on a smooth or inclined surface, for example, during transportation or installation.

[0003] Many material holders are difficult for users to handle, in part due to their generally round configuration and smooth surfaces. For example, a user may have difficulty gripping and picking up a material holder, especially when installing or removing a roll of media from a printer with many complex and closely packed parts. The absence of handles, flat surfaces, or other features that would facilitate convenient gripping and otherwise handling the material holder can increase the difficulty of tasks associated with operating or maintaining the printer (e.g., installing a new roll of media). This can lead to inconvenience, irritation, accidental drops, and other undesirable consequences for the consumer.

[0004] Material holders can also be a source of waste or pollution because they are typically made from plastic or other synthetic materials. Most material holders contain a variety of unique and complex parts that make them more difficult to maintain and more susceptible to damage or failure, i.e., more likely to require replacement. Ultimately, this means they have a shorter lifespan. Furthermore, many material holders are manufactured exclusively for use with a specific size of printable media and are configured symmetrically around a roll of this specific size of media. This lack of interchangeability and / or reusability translates into increased costs for consumers who want to print on different size media. Summary of the Invention [Problem to be solved by the invention]

[0005] In view of the above problems, a need exists for a material holder that resists rolling on smooth or inclined surfaces, is convenient to handle during installation and maintenance, and can be more easily and / or efficiently manufactured by using fewer parts or less overall material. It is also desirable for the material holder to be reusable, thereby reducing costs to the user and potentially reducing environmental waste. [Means for solving the problem]

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 embodiments of the present disclosure.

[0031] 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.

[0032] The present disclosure relates to a material holder designed to hold and dispense rolls of printable media having various widths. The material holder can be used with various types of printers. For example, the material holder 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 the printable media.

[0033] 1-3, an exemplary inkjet printer 100 may have 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 provided in the form of a base portion 106 and an enclosure cover 108. The base portion 106 and the enclosure cover 108 may be hingedly or otherwise coupled to one another to provide access to the internal components of the inkjet printer 100 and to allow the enclosure cover 108 to be removably opened and / or attached to allow installation and maintenance of the internal components. The enclosure cover 108 may be coupled to the base portion 106 through a hinge 124 or other attachment means (see FIG. 3).

[0034] Inkjet printer 100 may include one or more indicators 110 and one or more buttons 112 positioned on enclosure cover 108. In the example of FIG. 1 , inkjet printer 100 includes two indicators 110 and three buttons 112. However, inkjet printer 100 may include any number of indicators 110 and / or buttons 112. Indicators 110 may be positioned to alert a user to various operational states of inkjet printer 100. For example, indicators 110 may be provided in the form of light-emitting diodes (LEDs) configured to indicate to a user when inkjet printer 100 is powered on or low on ink. Alternatively, indicators 110 may be used for any other suitable purpose. Buttons 112 may be positioned to allow a user to operate, service, or otherwise interface with inkjet printer 100. For example, buttons 112 may be configured to allow a user to load new printable media into 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 .

[0035] 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.

[0036] 2 , the inkjet printer 100 may have a control area 116 positioned on the base portion 106. For example, the control area 116 may be positioned on the base portion 106 at the second end 104. In the illustrated example, the control area 116 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 (e.g., a smartphone, a desktop computer, a digital camera, etc.).

[0037] 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.

[0038] 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.

[0039] Although a particular exemplary inkjet printer 100 has been described, it should be appreciated that an inkjet printer 100 suitable for use with the material holder disclosed herein may include or exclude additional components known in the art.

[0040] 4-6, an exemplary thermal printer 160 suitable for use with the material holder disclosed 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.

[0041] 5, the thermal printer 160 can be designed to be articulated between a closed position, which places the second cover panel 166 flush with the first cover panel 164, and an open position, 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.

[0042] 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.

[0043] Although a particular exemplary thermal printer 160 has been described, it should be appreciated that a thermal printer 160 suitable for use with the material holders disclosed herein may include or exclude additional components known in the art.

[0044] 7-9 , an exemplary LED or laser printer 210 may include a feeder assembly 212, a printer device 214 positioned on and supported by the feeder assembly 212, 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 the printer device 214 may include a display 220 through which a user may 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. The printer device 214 may include a top cover 226 positioned opposite the feeder assembly 212. The take-up reel 216 may be positioned on a support plate 228. 8, which shows the rear side 230 of the laser printer 210 without the reel 216, the support plate 228 can be coupled to the rear side 230 through one or more fasteners 232. The laser printer 210 can also include one or more ports 234, one or more power outlets 236, and an exit slot 238 positioned on the rear side 230.

[0045] 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).

[0046] 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.

[0047] 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).

[0048] 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.

[0049] 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.

[0050] 10 , material holder 280 can be designed to hold and support rolls of printable media having various widths. Material holder 280 can be used in conjunction with inkjet printer 100, thermal printer 160, laser printer 210, or any other suitable printing device. For example, material holder 280 may be located in media area 126 of inkjet printer 100, in label well 182 of thermal printer 160, or in feeder assembly 212 of laser printer 210. Material holder 280 can be located in or otherwise configured for use with the printers disclosed herein in a manner known in the art.

[0051] The material holder 280 is provided in the form of a frame having two opposing flanges 282a, 282b, a spindle 284 positioned therebetween, and side clips 286. As best seen in Figure 10, the flanges 282a and 282b may be substantially identical to one another. However, it is contemplated that in other cases the material holder 280 may include one or more flanges 282 that are not identical.

[0052] Spindle 284 extends between flanges 282a and 282b and includes a substantially cylindrical arm 288 with a keyhole region 290 at one end. Keyhole region 290 can include a base 292 and a spindle handle 294 coupled to and extending upwardly from base 292. As best shown in FIG. 11 , side clip 286 can include an attachment zone 296 and a discontinuous side clip handle 298 positioned above and connected to attachment zone 296. The shape of side clip 286 can be a mirror image of or substantially similar to the shape of keyhole region 290 of spindle 284. For example, the shape of spindle handle 294 can be the same as or a mirror image of the shape of side clip handle 298.

[0053] Each flange 282 can include a central opening 300 configured to allow an arm 288 of a spindle 284 to pass therethrough. For example, the shape of the opening 300 can be a substantial mirror image of the exterior shape of the arm 288 or can be substantially circular. That is, each opening 300 can receive an arm 288 of a spindle 284 such that each of the flanges 282 a, 282 b can be slidably or adjustably coupled to the spindle 284 at any position along the arm 288. At the same time, the flanges 282 a, 282 b can be configured to rotate about the arm 288. The flanges 282 a, 282 b can be positioned on the spindle 284 such that the flanges 282 a, 282 b are spaced apart from one another along the arm 288. As best shown in FIG. 11 , the attachment zone 296 of the side clip 286 can be designed to facilitate secure attachment of the side clip 286 to the spindle 284 along the length of the arm 288. For example, side clip 286 can be attached to spindle 284 such that side clip 286 is positioned along arm 288 opposite flange 282a adjacent flange 282b.

[0054] In some cases, the flange 282, spindle 284, and side clip 286 may be formed from high-density polyethylene (HDPE). For example, the flange 282, spindle 284, and side clip 286 may be formed from Hostalen GC 7260, which has a resin code of 2 (e.g., it is highly recyclable). The flange 282, spindle 284, and side clip 286 may also be formed from polypropylene, although polypropylene is considered less recyclable than HDPE. In other cases, the flange 282, spindle 284, and side clip 286 may be formed from any suitable material having a coefficient of friction greater than 0 and less than about 0.4 and / or a resin code of 1 or 2.

[0055] 14-19, each flange 282 may be imparted with a substantially polygonal shape. A "polygonal shape" is a closed planar shape bounded by at least three sides. In one example depicted in FIG. 14, each flange 282 may be substantially octagonal in shape. However, in other examples, each flange 282 may be substantially triangular, rectangular, pentagonal, or any other suitable shape, including irregular shapes. By imparting a polygonal shape with substantially flat edges to flange 282, flange 282 may provide higher resistance to rolling or due to friction on smooth and / or inclined surfaces.

[0056] An annular ring 302 may be centrally disposed on an outer surface 304 of the flange 282. The ring 302 may be integrally formed with the flange 282 or may be coupled to and project outwardly from the outer surface 304. The rings 302 may each include a substantially smooth outer surface 306 and a first inner surface 308. The first inner surface 308 of the ring 302 may be provided with a size and shape substantially equal to the size and shape of the opening 300. The first inner surface 308 may be aligned with and substantially equal in size and shape to the first bearing surface 301. The first bearing surface 301 may be substantially cylindrical in shape and may define the opening 300. The ring 302 may have a stepped annular surface 310 adjacent to and extending between the outer surface 306 and the first inner surface 308.

[0057] Additionally, each flange 282 may include a driven gear 312 connected to the ring 302. The driven gear 312 may be integrally formed with the ring 302 or may be coupled to and protrude outwardly from the annular surface 310 of the ring 302. The driven gear 312 may be substantially annular in shape and may be substantially coaxial with the ring 302. A second inner surface 314 of the driven gear 312 may be substantially smooth. The driven gear 312 may have a plurality of teeth 316 surrounding it, evenly spaced along its circumference, and facing the second inner surface 314. In some cases, the teeth 316 of the driven gear 312 may be imparted with an involute, cycloid, or trochoid profile. In other cases, the teeth 316 may be imparted with any other suitable profile. The driven gear 312 can be configured to be aligned with and engaged by a gear drive assembly of a printer (not shown), such as the inkjet printer 100, the thermal printer 160, the laser printer 210, or any other suitable printing device, when the material holder is installed. The flange 282 is preferably not formed from a polycarbonate (PC) material because the coefficient of friction between the flange 282 and the gear drive assembly would be excessively high, which could lead to damage or malfunction of the material holder 280.

[0058] Each flange 282 defines a plurality of sectors 318 extending therearound. As shown in FIG. 14 , each flange 282 may include eight sectors 318A-318H that surround the ring 302. Each sector 318 may be substantially similar in shape and size. In other cases, each flange 282 may include any number of sectors 318 depending on the overall shape imparted to the flange 282. As shown in FIGS. 14 and 15 , a plurality of structural ribs 320 may extend between the ring 302 and a perimeter 322 of the flange 282. The structural ribs 320 may define lateral boundaries of the sectors 318, whereas upper and lower boundaries of the sectors 318 may be defined by the perimeter 322 of the flange 282 and the outer surface 306 of the ring 302, respectively. In some cases, each flange 282 includes eight structural ribs 320. However, in other cases, flange 282 can include any number of structural ribs 320 depending on the overall shape given to it.

[0059] Each sector 318 can be provided in the form of one of a solid window frame sector 324, a standard window sector 326, or an observation window sector 328. The solid window frame sector 324 can be opaque, whereas the standard window sector 326 and the observation window sector 328 can include through-holes that can provide visibility to a user (e.g., to observe how much of the roll of printable media is being used). The sectors 318 can be arranged such that each adjacent sector 318 alternates between a solid window frame sector 324 and either a standard window sector 326 or an observation window sector 328. However, in other cases, the sectors 318 can be arranged in any other suitable configuration. For example, in other cases, the flange 282 can include any number of sectors 318, all of which can be provided in the form of observation window sectors 328.

[0060] 14 , in some cases, sectors 318 can be configured such that flange 282 includes four solid window frame sectors 324, two standard window sectors 326, and two observation window sectors 328. For example, sectors 318B, 318D, 318F, 318H can be provided in the form of solid window frame sectors 324, sectors 318C, 318G can be provided in the form of standard window sectors 326, and sectors 318A, 318E can be provided in the form of observation window sectors 328.

[0061] As best shown in FIG. 15 , each observation window sector 328 can include a proximal end 330 and a distal end 332. The proximal end 330, the distal end 332, and two adjacent structural ribs 320 can define the boundary of the observation window sector 328. An observation window 334 can be disposed between the proximal end 330 and the distal end 332 and between the two adjacent structural ribs 320. The observation window 334 can include a core observation notch 336 positioned adjacent the proximal end 330. The core observation notch 336 can be provided in the form of an arched-top rectangle having an “arched top” positioned adjacent the proximal end 330. However, in other cases, the core observation notch 336 can be provided in any suitable shape. The core observation notch 336, together with the observation window 334, can allow a user to observe how much of the roll of printable media (not shown) remains relative to the core of the roll.

[0062] The observation window sector 328 may also include an outer locating notch 338 positioned adjacent the distal end 332. The outer locating notch 338 may be disposed on the periphery 322 and positioned approximately equidistant from each of two adjacent structural ribs 320. The outer locating notch 338 may be provided in the form of a triangular divot or indentation with rounded edges. However, in other cases, the outer locating notch may have any other suitable shape or configuration. When installing a roll of printable media (not shown), the outer locating notch 338 may assist the user in positioning the roll symmetrically and centrally with respect to the one or more flanges 282.

[0063] Turning now to FIG. 16, a media roll 340 for use with the material holder 280 disclosed herein is shown. The media roll 340 can include a core 342 and a media supply 344 and can be positioned or located between flanges 282a and 282b (see FIG. 44C). The core 342 can be provided in the form of an annular cylinder and can be formed from cardboard or any other suitable material. The media roll 340 can be defined by a width W that can extend linearly in a direction substantially parallel to the axis of radial symmetry of the media roll 340.

[0064] The media supply 344 can be provided in the form of a continuous strip of printable media. For example, in some cases, the media supply 344 can be provided in the form of a continuous strip of liner 346 having a plurality of adhesive labels 348 positioned thereon and evenly spaced from one another. However, in other cases, the media supply 344 can be provided in the form of any other printable media (e.g., a roll of end-to-end connected wristbands, a roll of paper, a roll of end-to-end connected tags, a roll of plastic, a roll of magnetic material or foil, a roll of a continuous strip of adhesive labels optionally positioned on a continuous strip of liner, etc.). In some cases, the media supply 344 can be wrapped around the core 342 such that the media supply 344 forms a neatly wound, multi-layer roll. That is, the media supply 344 can unwind smoothly from the outermost layer inward as the media supply 344 is used during the printing process.

[0065] When the media supply 344 is wound around the core 342, the media supply 344 may be defined by a thickness T. The thickness T may be measured radially between the outer diameter 350 of the core 342 and the outer circumference 352 of the media roll 340. As the media supply 344 is used, the thickness T may decrease. Thus, the thickness T may indicate the life of the media roll 340 (e.g., how much media supply 344 is remaining before the media roll 340 must be replaced).

[0066] 17 , the observation window sectors 328 can allow a user to observe or at least estimate the thickness T (e.g., determine how much of the media supply 344 remains) without disassembling the material holder 280. When the media roll 340 is positioned between the two flanges 282, at least a portion of the core 342 can be visible through the core observation notch 336. Furthermore, at least a portion of the media supply 344 can be visible through the observation window 334 and / or the outer positioning notch 338. That is, one or more of the observation window sectors 328 can allow a user to observe or estimate the thickness T of the media supply 344.

[0067] The outer locating notch 338 can expose a portion of the media supply 344. For example, a first visible portion 354A of the media supply 344 can be visible through the outer locating notch 338 of sector 318A, and a second visible portion 354E of the media supply 344 can be visible through the outer locating notch 338 of sector 318E. That is, by comparing the first visible portion 354A and the second visible portion 354E, a user can orient the media roll 340 centrally and symmetrically about the one or more flanges 282. For example, a user can adjust the positioning of the media roll 340 so that the portions of the outer locating notch 338 that appear to be occupied by the first and second visible portions 354A, 354E are substantially equal.

[0068] 18 , the rear surface 356 of each flange 282 can have a toothed ring 358 connected thereto. The first bearing surface 301 can form the inner surface of a hub 360. The hub 360 can be integrally formed with the rear surface 356 or can be coupled to the rear surface 356 and project outwardly therefrom. The toothed ring 358 and the hub 360 can be substantially coaxial (e.g., concentric), and each can be substantially cylindrical in shape.

[0069] The flange 282 may also include a support structure 362 disposed between the toothed ring 358 and the hub 360. The support structure 362 may be provided in the form of a plurality of spokes 364 and a support ring 366. The plurality of spokes 364 may be evenly spaced from one another and may extend radially between the toothed ring 358 and the hub 360. The support ring 366 may be disposed between the toothed ring 358 and the hub 360 and may be substantially coaxial therewith. The support ring 366 may be connected to or integrally formed with the plurality of spokes 364 and may extend in a circular manner between the plurality of spokes 364. However, in other cases, the support structure 362 may be provided in any other suitable form. The support structure 362 may, for example, add stability and / or structural rigidity to the toothed ring 358, the hub 360, and / or other components of the flange 282.

[0070] The peripheral ring 368 may surround the toothed ring 358. One or more core observation notches 336 may be positioned along the circumference of the peripheral ring 368. Excluding the core observation notches 336, the peripheral ring 368 may be substantially circular in shape and may be substantially coaxial (e.g., concentric) with the toothed ring 358, the support ring 366, and / or the hub 360. The peripheral ring 368 may be integrally formed with the rear surface 356 or may be coupled to and protrude outwardly therefrom. A plurality of openings 370 may be formed in the rear surface 356. The plurality of openings 370 may be disposed between the peripheral ring 368 and the toothed ring 358 and may be radially spaced apart from one another. As best seen in FIG. 18 , the plurality of openings 370 may be radially aligned with the plurality of spokes 364 of the support structure 362. However, in other cases, flange 282 may be provided with any number of openings 370, and the openings 370 may be positioned in any suitable configuration.

[0071] The barbs 372 may surround the toothed ring 358. The barbs 372 may be configured to engage with (e.g., penetrate into) the core 342 (e.g., a cardboard core) of the media roll 340 when the material holder 280 is assembled for use. As best shown in FIG. 19 , the barbs 372 may connect to and radially protrude away from an angled wall 374 of the toothed ring 358. In some cases, the barbs 372 may be provided with a “snake-bite” shape. In other cases, the barbs 372 may be provided with an angled shape or any other suitable shape that causes releasable engagement between the barbs 372 and the core 342 of the media roll 340. In this manner, the barbs 372 may increase the amount of engagement between the flange 282 and the core 342 through cylindrical hoop stress.

[0072] As can be seen in FIG. 19 , each barb 372 can be provided in the form of a body portion 376 and an end portion 378. The shape of the body portion 376 can be defined by a wedge having a base 380 positioned proximate the end portion 378 and an opposite point 382. For example, the body portion 376 can protrude from the angled wall 374 of the toothed ring 358 by a greater amount at the base 380 than at the point 382. An upper surface 384 of the body portion 376 can extend between the first and second ends 380, 382. The upper surface 384 can be given an inclined shape, and can curve downward (toward the toothed ring 358) from the base 380 to the point 382. For example, the upper surface 384 can be substantially parabolic, concave, logarithmic, or any other suitable shape. In other cases, the upper surface 384 can be substantially straight.

[0073] End portion 378 may include a first side 386 adjacent to body portion 376 and an opposing second side 388. First side 386 may be substantially straight, while second side 388 may be imparted with a parabolic or other curved shape. End portion 378 may be integrally formed with body portion 376 or may be coupled to body portion 376 by abutting first side 386 of end portion 378 with base 380 of body portion 376.

[0074] 20 and 21 , the spindle 284 can provide an axis about which the media roll 340 rotates. The spindle 284 can generally include an arm 288 and a keyhole region 290 that includes a base 292 and a spindle handle 294. The arm 288 can be integrally formed with the keyhole region 290 or can be coupled to and extend outward from an inner surface 410 of the keyhole region 290. The arm 288 is defined by a first end 412 proximate the keyhole region 290 and an opposing second end 414. A smart cell bay 416 can be disposed on an outer surface 418 of the keyhole region 290. The outer surface 418 can be positioned opposite the inner surface 410. The smart cell bay 416 can be integrally formed with the keyhole region 290 or can be coupled to and extend outward from the outer surface 418. The smart cell bay 416 is provided in the form of a housing 420 having a plurality of support elements 422 coupled thereto and extending inwardly therefrom.

[0075] 22 and viewed clockwise around arm 288, arm 288 is defined by a top portion 424, a first side rail 426, a bottom portion 428, and a second side rail 430. Top portion 424, first side rail 426, bottom portion 428, and second side rail 430 may be configured to impart a substantially T-shape to arm 288. Second bearing surface segments 432A-432D may be formed on the outermost surfaces of top portion 424, first side rail 426, bottom portion 428, and second side rail 430, respectively. Each of second bearing surface segments 432A-432D may be provided in the form of an arc (i.e., a segment or portion) derived from a single substantially circular or elliptical shape. Together, the second bearing surface segments 432A-423D can define a second bearing surface 432 that corresponds to and is substantially a mirror image of the shape of the first bearing surface 301 of one or more flanges 282.

[0076] Junctions 434A-434D can be disposed between any two of the top portion 424, first side rail 426, bottom portion 428, and second side rail 430. For example, the top portion 424 and first side rail 426 can be adjacent at junction 434A, the first side rail 426 and bottom portion 428 can be adjacent at junction 434B, the bottom portion 428 and second side rail 430 can be adjacent at junction 434C, and the second side rail 430 and top portion 424 can be adjacent at junction 434D. As shown in FIG. 22 , each of the junctions 434A-434D can be provided in the form of a right angle. However, in other cases, the junctions 434A-434D can be provided in any suitable shape.

[0077] 23, the first side rail 426 can be provided with a first serrated surface 436 disposed above it (e.g., adjacent the top portion 424) and a second serrated surface 438 disposed below it (e.g., adjacent the bottom portion 428). The first serrated surface 436 can include a first plurality of teeth 440, and the second serrated surface 438 can include a second plurality of teeth 442. As best shown in FIG. 22, the first plurality of teeth 440 can connect to and extend upwardly from the first side rail 426 adjacent junction 434A, and the second plurality of teeth 442 can connect to and extend downwardly from the first side rail 426 adjacent junction 434B.

[0078] The second side rail 430 shown in FIG. 24 can be provided in substantially the same configuration as the first side rail 426. The second side rail 430 can include a third serrated surface 444 disposed below it (e.g., adjacent the bottom portion 428) and a fourth serrated surface 446 disposed above it (e.g., adjacent the top portion 424). The third serrated surface 444 can include a third plurality of teeth 448, and the fourth serrated surface 446 can include a fourth plurality of teeth 450. Referring again to FIG. 22, the third plurality of teeth 448 can connect to and extend downwardly from the second side rail 430 adjacent junction 434C, and the fourth plurality of teeth 450 can connect to and extend upwardly from the second side rail 430 adjacent junction 434D.

[0079] The first, second, third, and fourth pluralities of teeth 440, 442, 448, 450 can be provided in the form of, for example, buttress thread-style teeth. Alternatively, the first, second, third, and fourth pluralities of teeth 440, 442, 448, 450 can be provided in the form of sawtooth-style teeth or breechlock-style teeth. In other cases, the first, second, third, and fourth pluralities of teeth 440, 442, 448, 450 can be provided in any other suitable form. In some forms, one or more of the first, second, third, and fourth pluralities of teeth 440, 442, 448, 450 can be provided with a different configuration relative to one of the other first, second, third, and fourth pluralities of teeth 440, 442, 448, 450.

[0080] 23 and 24, the arm 288 projects outwardly from the base 292 of the keyhole region 290 and terminates in an end protrusion 452 positioned opposite the keyhole region 290. The end protrusion 452 can include a body portion 456, which can be substantially rectangular in shape or rectilinear in configuration, and an appendage 458 connected to the body portion 456 and extending downwardly therefrom.

[0081] The arm 288 may also include a wall stop 460 and a spring tab 462 having a catch 464. The wall stop 460 may be positioned on the top portion 424 adjacent to the base 292 of the keyhole area 290. The spring tab 462 may also be positioned on the top portion 424 adjacent to the base 292 and may abut the wall stop 460.

[0082] The positioning wall 466 can be disposed below the base 292 of the keyhole region 290 (e.g., on the opposite side of the base 292 from the spindle handle 294). The positioning wall 466 can include a first end 468 adjacent the base 292 and an opposing second end 470. The positioning wall 466 can be integrally formed with the keyhole region 290 and / or the arm 288, or can be coupled to and extend downwardly therefrom. The positioning wall 466 can be configured such that a gap 472 is formed between the positioning wall 466 and the bottom portion 428 of the arm 288. The gap 472 can be, for example, substantially rectangular in shape. However, in other cases, the gap 472 can have any suitable shape.

[0083] The positioning wall 466 projects downwardly from the first end 468 of the base 292 and terminates in a chamfered surface 474. The chamfered surface 474 defines a sloped edge of the positioning wall 466. For example, due to the chamfered surface 474, the positioning wall 466 can have a greater width (measured in a direction substantially parallel to the arm 288) at the first end 468 than at the second end 470.

[0084] As best shown in FIG. 25 , the positioning wall 466 can be substantially semicircular in shape. Accordingly, the chamfered surface 474 can be provided in the form of an arc that substantially mirrors the curvature of the positioning wall 466 and can be disposed about the periphery 476 of the positioning wall 466 and defined by an angle A (see FIG. 26 ). Angle A can have a value of about 10 to about 80 degrees. For example, angle A can have a value of about 20 to about 70 degrees, about 30 to about 60 degrees, or about 40 to about 50 degrees. In some cases, angle A can have a value of about 45 degrees. However, in other cases, angle A can have any suitable value. The chamfered surface 474 can assist in the placement of the material holder 280. For example, the chamfered surface 474 can be positioned to align with and be received by a complementary beveled surface of a printer (e.g., inkjet printer 100, thermal printer 160, laser printer 210, or any other suitable printing device) when the material holder 280 is installed for use (see FIG. 34). For at least this reason, the positioning wall 466 can assist a user in installing the material holder 280 in the printer in the proper orientation and / or position.

[0085] As best shown in FIG. 27 , the wall stop 460 may project upward from the upper portion 424 and terminate in a canopy 478 provided in the form of a substantially smooth, curved surface. The curvature of the canopy 478 may substantially mirror the curvature of the second bearing surface segment 432A. The spring tab 462 may be positioned on an opposite side of the base 292 with respect to the wall stop 460. A first end 480 of the spring tab 462 may abut the wall stop 460. A catch 464 may be positioned on a second end 482 of the spring tab 462 opposite the first end 480. The catch 464 may be integrally formed with the spring tab 462 or may be coupled to and extend upwardly therefrom.

[0086] The channel 484 can surround the spring tab 462 on at least one side. As shown in FIG. 27 , the channel 484 can surround the spring tab 462 on three sides (excluding the side of the spring tab 462 at the first end 480 where the spring tab 462 and wall stop 460 abut). The channel 484 can be provided in the form of an angular recess or trough formed around and adjacent the spring tab 462 in the top portion 424. However, in other cases, the channel 484 can be provided in any suitable form and positioned in any suitable manner.

[0087] The arm 288 may include a poke yoke 486 provided in the form of a linear recess or channel formed or milled in the top portion 424. For example, referring to FIG. 22 , the poke yoke 486 may be disposed between the joint 434A and the second bearing surface segment 432A. As best seen in FIG. 27 , the poke yoke 486 is defined by a floor 488, a sidewall 490, and a backstop 492. However, in other cases, the poke yoke 486 may have any suitable shape or configuration. The poke yoke 486 may extend along at least a portion of the length of the top portion 424. The backstop 492 may be positioned proximate the second end 470 of the spring tab 462. The floor 488 and the sidewall 490 may extend linearly in a direction substantially parallel to the arm 288 between the backstop 492 and the distal end 454 of the arm 288. However, in other cases, the poke yoke 486 may be positioned in any other suitable manner.

[0088] 30-32, the flange 282a can be installed or docked onto the spindle 284 by engagement with the spring tab 462. For example, the flange 282a can be disposed along the arm 288 and positioned adjacent the keyhole region 290. The flange 282a can slide over the spring tab 462 such that the catch 464 engages the hub 360 and prevents the flange 282a from unintentionally moving away from the keyhole region 290. The engagement between the catch 464 and the hub 360 can rigidly couple the flange 282a and the spindle 284 together, thereby reducing the likelihood of the material holder 280 becoming damaged or disassembled during use, transportation, or in the event of an accident (e.g., dropping the material holder 280). The catch 464, together with the wall stop 460, can position the flange 282a as close as possible to the keyhole region 290 of the spindle 284. Preventing the flange 282a from tracking or moving linearly along the arm 288 away from the keyhole region 290 can increase engagement between the driven gear 312 and a gear drive assembly (not shown) of a printer (e.g., inkjet printer 100, thermal printer 160, laser printer 210, or any other suitable printing device) in which the material holder 280 is used.

[0089] The flange 282a and spindle 284 can be designed and configured to have complementary shapes that can facilitate a secure fit when the flange 282a is placed adjacent the keyhole region 290 on the spindle 284. As best shown in the cross-sectional view of FIG. 32 , in some cases, the hub 360 can engage and surround the arm 288 such that the first bearing surface 301 is substantially flush with the spring tab 462. The hub 360 can have a catch 464 on one side and a stop 460 on the other side disposed therebetween, with the annular surface 310 of the ring 302 being substantially flush with the stop 460. In other cases, the flange 282a and spindle 284 can be provided with any suitable complementary shapes or structural features that facilitate engagement.

[0090] 33 , the spindle 284 can include a smart cell 510 designed to be placed in the smart cell bay 416. In particular, the smart cell 510 can be positioned within a housing 420 of the smart cell bay 416 and can be at least partially secured in place by a plurality of peripheral support elements 422. To help prevent the smart cell 510 from coming loose or being unintentionally ejected from the smart cell bay 416 (e.g., if the spindle 284 is dropped), a smart cell cover 512 can be provided having a barbed member 514 and an opening 516. The barbed member 514 of the smart cell cover 512 can correspond to a receiving member (not shown) located within the housing 420. Thus, after placing the smart cell 510 within the housing 420, the opening 516 of the smart cell cover 512 can be aligned with the smart cell 510, and the smart cell cover 512 can be pushed toward the spindle 284 until the barbed member 514 engages the receiving member of the housing 420. This engagement between barbed member 514 and the receiving member of housing 420 can secure smart cell cover 512 in place, thus securing smart cell 510. To remove smart cell cover 512 and / or smart cell 510, a user can press button 518 positioned on housing 420. Button 518 can be aligned with the position of barbed member 514 within housing 420 such that pressing button 518 applies downward pressure to barbed member 514, disengaging barbed member 514 from the receiving member of housing 420.

[0091] The smart cell 510 can include one or more conductive window frames 520. In the example of Figure 33, the smart cell 510 includes three conductive window frames 520. However, in other cases, the smart cell 510 can include any number of conductive window frames 520. The conductive window frames 520 can facilitate electrical connection or communication between the smart cell 510 and a printer (e.g., inkjet printer 100, thermal printer 160, laser printer 210, or any other suitable printing device) in which the material holder 280 is used.

[0092] As best shown in FIG. 34 , the material holder can be used with a printer 522 that includes one or more contacts 524 configured to read the smart cell 510. The printer 522 can further include a chassis 526 that includes a positioning fixture 528. The positioning fixture 528 can correspond to and / or complement the positioning wall 466 of the spindle 284 such that, when the material holder 280 is installed in the printer 522, the chassis 526 can ensure that the spindle 284 is positioned such that the smart cell 510 can be read by the contacts 524. In this manner, the positioning wall 466 can prevent the material holder 280 from being installed backwards. Additionally, the positioning fixture 528 can include an angled member 529 that can be configured to align with and receive the chamfered surface 474 of the positioning wall 466, thereby ensuring proper orientation and / or positioning of the material holder 280 relative to the printer 522.

[0093] The smart cell 510 can identify the material holder 280 and / or the media roll 340 provided thereby as either suitable or unsuitable for use with the printer 522. For example, the printer 522 can be designed to work only with printable media produced by a particular manufacturer. In this case, the printer 522 can read the smart cell 510 through contacts 524 to determine whether the material holder 280 and / or media roll 340 are produced by the desired manufacturer. If the determination is true, the printer 522 can proceed with printing or another operation. If the determination is not true, the printer 522 can be disabled until the appropriate material holder 280 and / or media roll 340 is installed. In the example of FIG. 34 , the printer 522 is not shown in its entirety, but it could be provided in substantially the same form as the inkjet printer 100, thermal printer 160, laser printer 210, or any other suitable printing device.

[0094] 35 , the side clip 286 can have a body 540 defined by a first end 550 and an opposing second end 552. Similarly, the side clip 286 can have a first side 554 and an opposing second side 556. The body 540 is defined by an attachment zone 296 proximate the first end 550, a side clip handle 298 proximate the second end 552, and a mid-section 558 disposed between the attachment zone 296 and the side clip handle 298. The mid-section 558 can have a bottom end 560 proximate the attachment zone 296 and a top end 562 proximate the side clip handle 298. In some cases, the attachment zone 296, the side clip handle 298, and the mid-section 558 can be integrally formed with one another. In other cases, the attachment zone 296 can connect to and extend downwardly from the bottom end 560 of the middle section 558, and the side clip handle 298 can connect to and extend upwardly from the top end 562 of the middle section 558.

[0095] In some cases, the side clip may include a first locking mechanism 564, a second locking mechanism 566, and a living hinge 568. The first locking mechanism 564 may be positioned on the attachment zone 296 proximate the first end 550 of the side clip 286. The second locking mechanism 566 may be disposed on the mid-section 558 between the attachment zone 296 and the side clip handle 298. The living hinge 568 may be positioned on the side clip handle 298 proximate the second end 552 of the side clip 286.

[0096] The side clip 286 can include a first half 570 and a second half 572 and is designed to articulate between an open configuration and a closed configuration. The first half 570 and the second half 572 can be rotatably coupled to one another through a living hinge 568 and can be releasably coupled to one another through first and second locking mechanisms 564, 566. To transition the side clip 286 between the closed configuration (shown in FIG. 35 ) and the open configuration (shown in FIG. 36 ), a user can rotate one of the first or second halves 570, 572 relative to the other about the living hinge 568.

[0097] 36 , the side clip 286 can include an extension member 574 and a seat member 576, each of which can be positioned adjacent the living hinge 568 at the second end 552 of the side clip 286. The extension member 574 and the seat member 576 can be designed and positioned to complement one another such that the seat member 576 can receive the extension member 574 when the side clip 286 is transitioned from the open configuration to the closed configuration.

[0098] The second locking mechanism 566 can be provided with a rounded interference shape to enable the side clips 286 to snap together when the side clips 286 are transitioned from the open configuration to the closed configuration. For example, the second locking mechanism can include a first stud 578 and a first fitting member 580 disposed in the mid-section 558 on the first half 570, and a second stud 582 and a second fitting member 584 disposed in the mid-section 558 on the second half 572. The first fitting member 580 can be positioned on the first half 570 such that it can abut or be positioned adjacent to the bottom end 560 of the mid-section 558, whereas the second fitting member 584 can be positioned on the second half 572 such that it can abut or be positioned adjacent to the top end 562 of the mid-section 558.

[0099] The first fit member 580 may include a first mating surface 586 positioned opposite the bottom end 560 of the mid-section 558. The second fit member 584 may include a second mating surface 588 positioned opposite the top end 562 of the mid-section 558. Each of the first and second mating surfaces 586, 588 may be imparted with a curved shape. For example, the first mating surface 586 may be imparted with a concave shape, and the second mating surface 588 may be imparted with a convex shape that substantially mirrors and / or complements the concave shape of the first mating surface 586. That is, the first and second fit members 580, 584 may facilitate a “snap-fit” connection between the first half 570 and the second half 572. For example, the first and second mating surfaces 586, 588 can enable the first fitting member 580 and the second fitting member 584 to be coupled to one another, such as by a press fit or interference fit, when the side clip 286 is switched from an open configuration to a closed configuration.

[0100] Coupling between the first half 570 and second half 572 of the side clip 286 can be facilitated by a first locking mechanism 564. The first locking mechanism 564 can be provided in the form of a tab or insert positioned on the first half 570 of the side clip 286 that "snaps" into a housing or cavity positioned on the second half 572 of the side clip 286. For example, as best shown in FIGS. 37-39 , the first locking mechanism 564 can include an insert 590 disposed at the first end 550 on the first half 570 of the side clip 286 (see FIG. 37 ). The insert 590 can include a hook 592. The first locking mechanism 564 can further include a cavity 594 formed in the second half 572 at the first end 550 of the side clip 286 (see FIG. 38 ). The cavity 594 can be positioned to receive an insert 590 (see FIG. 39).

[0101] As best seen in FIG. 37 , the insert 590 can be substantially linear in shape. However, in other cases, the insert 590 can be given any suitable shape or configuration. The insert 590 can be integrally formed with the first half 570 of the side clip 286, or a proximal end 596 of the insert 590 can be coupled to the first half 570 and the insert 590 can extend outward therefrom. The hook 592 can be located on a distal end 598 of the insert 590 opposite the proximal end 596.

[0102] 38 , cavity 594 may include a first opening 600 that may be substantially rectangular in shape. However, in other cases, insert 590 and / or first opening 600 may be provided with any suitable shape or size. Meanwhile, cavity 594 and first opening 600 may be configured such that cavity 594 can receive distal end 598 of insert 590 when side clip 286 is switched from the open configuration to the closed configuration.

[0103] As best shown in FIG. 39 , when the insert 590 is positioned within the cavity 594 (not shown in FIG. 39 ), the first half 570 and the second half 572 can be within a very short distance of each other or can directly contact each other. In some cases, the insert 590 can extend through a second opening 602 in the cavity 594. The second opening 602 can be positioned opposite the first opening 600. When the distal end 598 of the insert 590 extends through the second opening 602, the hook 592 can engage the first end 550 of the second half 572 and prevent the insert 590 from being pulled back out of the cavity 594 through the first opening 600. To disengage the first locking mechanism 564, a user can apply upward pressure to the hook 592 such that the hook 592 disengages from the first end 550 of the second half 572 of the side clip 286. That is, a user can remove the insert 590 from the cavity 594 by rotating the first half 570 away from the second half 572 through the living hinge 568 (e.g., simultaneously disengaging the second locking mechanism 566).

[0104] 40 and 41 , the second locking mechanism 566 can be positioned in the midsection 558 between the first side 554 and the second side 556 of the side clip 286. The second locking mechanism 566 can facilitate coupling between the first half 570 and the second half 572 of the side clip 286, for example, by a press fit or other connection between the first fitting member 580 and the second fitting member 584 as described above with reference to FIG. 36 . The second locking mechanism 566 can include one or more lap elements that can limit twisting about its center (e.g., forces that may oppose the fit between the first fitting member 580 and the second fitting member 584). In this manner, the one or more lap elements can mitigate potential failure of the second locking mechanism 566. For example, a first lap splice element 604 can be formed between the first fitting member 580 and the second stud 582 at the bottom end 560 of the mid-section 558. A second lap splice element 606 can be formed between the second fitting member 584 and the first stud 578 at the top end 562 of the mid-section 558.

[0105] The attachment zone 296 can be designed to facilitate coupling between the side clip 286 and the arm 288 of the spindle 284. As best seen in FIG. 41 , the outer surface 608 of the attachment zone 296 can be substantially cylindrical in shape, except that it can include a first base member 610 disposed at the first end 550 of the first half 570 and a second base member 612 disposed at the first end 550 of the second half 572. The first and second base members 610, 612 can be integrally formed with the first and second halves 570, 572, respectively, or can be coupled to and minimally extend downwardly therefrom. The second base member 612 can be adjacent to and substantially flush with the first base member 610. For example, together, the first base member 610 and the second base member 612 can provide a flat inner surface on which the side clips 286 can rest in an upright position. In this manner, the first and second base members 610, 612 can provide security and stability to the material holder 280.

[0106] The interior of the mounting zone 296 (e.g., the surface positioned opposite the exterior surface 608) may be provided with structural features that may mirror and / or complement the structural features of the arm 288 of the spindle 284.

[0107] For example, the attachment zone 296 can include inner curved surface segments 614A-614D corresponding to the second bearing surface segments 432A-432D of the arm 288. The inner curved surface segment 614A can be positioned proximate the mid-section 558 and can include at least a portion disposed on each of the first and second halves 570, 572 of the side clip 286. The inner curved surface segment 614A can be provided with a curved shape that mirrors or complements the curved shape of the second bearing surface segment 432A. The inner curved surface segment 614B can be positioned on the second half 572 between the mid-section 558 and the first end 550 and can be provided with a curved shape that mirrors or complements the curved shape of the second bearing surface segment 432B. The inner curved surface segment 614C can be positioned opposite the inner curved surface segment 614A proximate the first end 550 and can include at least a portion positioned on each of the first and second halves 570, 572 of the side clip 286. The inner curved surface segment 614C can be provided with a curved shape that is a mirror image or complementary to the curved shape of the second bearing surface segment 432C. The inner curved surface segment 614D can be positioned on the first half 570 between the mid-section 558 and the first end 550 and can be provided with a curved shape that is a mirror image or complementary to the curved shape of the second bearing surface segment 432D.

[0108] Additionally, attachment zone 296 can include ledges 616A-616D that can correspond to joints 434A-434D of arm 288. For example, ledge 616A can be positioned between inner curved surface segment 614A and inner curved surface segment 614B and can be configured to be received by joint 434A. For example, ledge 616B can be positioned between inner curved surface segment 614B and inner curved surface segment 614C and can be configured to be received by joint 434B. Ledge 616C can be positioned between inner curved surface segment 614C and inner curved surface segment 614D and can be configured to be received by joint 434C. Ledge 616D can be positioned between inner curved surface segment 614D and inner curved surface segment 614A and can be configured to be received by joint 434D.

[0109] The mounting zone 296 may further include an orientation ledge 618 disposed between the inner curved surface segment 614A and the ledge 616A. The orientation ledge 618 may be configured to correspond to and be received by the spoke yoke 486. That is, the orientation ledge 618 may ensure that the side clip 286 is properly oriented on the arm 288 of the spindle 284.

[0110] The attachment zone 296 can include a fifth serrated surface 620 having a fifth plurality of teeth 622 (see FIG. 41 ), a sixth serrated surface 624 having a sixth plurality of teeth 626 (see FIG. 40 ), a seventh serrated surface 628 having a seventh plurality of teeth 630 (see FIG. 40 ), and an eighth serrated surface 632 having an eighth plurality of teeth 634 (see FIG. 41 ). The fifth serrated surface 620 can be disposed on a ledge 616A, from which the fifth plurality of teeth 622 can protrude toward the first end 550 of the side clip 286. The sixth serrated surface 624 can be disposed on a ledge 616B, from which the sixth plurality of teeth 626 can protrude toward the second end 552 of the side clip 286. The seventh serrated surface 628 can be disposed on the ledge 616C from which the seventh plurality of teeth 630 can project toward the second end 552. The eighth serrated surface 632 can be disposed on the ledge 616D from which the eighth plurality of teeth 634 can project toward the first end 550. Each of the fifth, sixth, seventh, and eighth pluralities of teeth 622, 626, 630, 634 can be provided in a configuration complementary to the structure and shape of the first, second, third, and fourth pluralities of teeth 440, 442, 448, 450.

[0111] 42 illustrates an example of engagement between the fifth plurality of teeth 622 and the first plurality of teeth 440 and between the sixth plurality of teeth 626 and the second plurality of teeth 442, respectively, when the side clip 286 is installed on the arm 288. The fifth and sixth plurality of teeth 622, 626 may be provided in the form of unidirectional teeth that can reduce side loads resulting from tracking or accidental dropping. However, in other cases, the fifth and sixth plurality of teeth 622, 626 may be provided with any suitable form that provides engagement between the fifth plurality of teeth 622 and the first plurality of teeth 440 and between the sixth plurality of teeth 626 and the second plurality of teeth 442, respectively. The above is equally true with respect to the seventh and eighth plurality of teeth 630, 634 and the third and fourth plurality of teeth 448, 450.

[0112] That is, as can be seen in FIG. 43 , when the side clip 286 is installed on the arm 288, the first serrated surface 436 can align with and engage the fifth serrated surface 620, the second serrated surface 438 can align with and engage the sixth serrated surface 624, the third serrated surface 444 (not shown in FIG. 43 ) can align with and engage the seventh serrated surface 628 (not shown in FIG. 43 ), and the fourth serrated surface 446 can align with and engage the eighth serrated surface 632. This engagement between the attachment zone 296 and the arm 288 can prevent the side clip 286 from unintentionally tracking or moving relative to the arm 288, for example, when the material holder 280 is being used or transported.

[0113] 44A-44D, a method of assembling a material holder 280 for use with a printer (e.g., inkjet printer 100, thermal printer 160, or laser printer 210) is described. As shown in FIG. 44A, a first flange 282a is installed on a spindle 286. In particular, a user can insert a distal end 454 of an arm 288 of the spindle 286 into an opening 300 in the first flange 282a. A user can move the first flange 282a along the entire length of the arm 288 toward the keyhole region 290 until the first flange 282a is received by the spring tab 462, as described above with reference to FIGS. 30-32. For example, when installed, the first flange 282a can be positioned or secured between the catch 464 and the base 292 of the keyhole region 290. The first flange 282a can be oriented on the arm 288 with its driven gear 312 abutting the base 292 of the keyhole region 290. The toothed ring 358 can extend from the first flange 282a toward the distal end 454 of the arm 288 and can be configured to receive the media roll 340.

[0114] As shown in FIG. 44B , the media roll 340 is positioned adjacent to the first flange 282a along the arm 288 of the spindle 284. A user can use the outer locating notch 338 of the first flange 282a to symmetrically and centrally align the media roll 340 with respect to the first flange 282a, as described above with reference to FIG. 17 . A user can push the media roll 340 toward the first flange 282a to engage the toothed ring 358 with the core 342 (cardboard core) of the media roll 340. For example, the core 342 can be given a circular profile having substantially the same dimensions as the toothed ring 358. That is, when the media roll 340 is pushed into the first flange 282a, the core 342 can slide over the barb 372, which can engage the inner surface 636 of the core 342. This engagement can couple the media roll 340 to the first flange 282a through a press fit, an interference fit, a friction fit, etc. The barbs 372 (described above with reference to FIG. 19) can increase the amount of engagement between the toothed ring 358 of the first flange 282a and the core 342 of the media roll 340 through cylindrical hoop stress.

[0115] 44C , the second flange 282b is positioned such that the media roll 340 is sandwiched between the first flange 282a on one side (e.g., adjacent the keyhole region 290) and the second flange 282b on the other side (e.g., adjacent the distal end 454 of the arm 288). For example, a user can position the second flange 282b along the arm 288 adjacent to the media roll 340. A user can reverse the orientation of the second flange 282b relative to the first flange 282a (i.e., the toothed ring 358 of the second flange 282b can directly abut the core 342 of the media roll 340, while the driven gear 312 of the second flange 282b can face the distal end 454 of the arm 288). A user can use the outer locating notches 338 of the second flange 282b to symmetrically and centrally align the second flange 282b with the media roll 340, as described above with reference to FIG. 17 . Next, the user can push the second flange 282b forward so that the toothed ring 358 can engage the inner surface 636 of the core 342. That is, the second flange 282b can become coupled to the media roll 340 (and consequently to the first flange 282a) through a press fit, interference fit, friction fit, or other engagement between the toothed ring 358 and the core 342. That is, the first flange 282a, the media roll 340, and the second flange 282b can be combined into a single unit that can be held in place by engagement between the spring tab 462 of the spindle 284 and the first flange 282a. In this manner, the material holder 280 can be properly justified. For example, the unit formed by the first flange 282a, the media roll 340, and the second flange 282b can be affixed to the side of the material holder 280 corresponding to the keyhole region 290 (e.g., the right side of the material holder 280 in FIG. 44C ). This justification can allow the material holder 280 to hold media rolls 340 having different sizes, as described below with reference to FIG. 45 .

[0116] FIG. 44D depicts the installation of the side clip 286 on the material holder 280. The side clip 286 can stabilize the first flange 282a, the media roll 340, and the second flange 282b relative to the arm 288 (e.g., resist or prevent them from tracking). A user can position the side clip 286 in the open configuration as shown in FIG. 36. A user can position the side clip 286 adjacent to the second flange 282b and orient the side clip so that the attachment zone 296 is positioned in alignment with the arm 288 of the spindle 284 as described above with reference to FIGS. 40-43. Once the side clip 286 is properly positioned, a user can rotate one of the first and second halves 570, 572 about the living hinge 568 until it comes into contact with the other of the second halves 570, 572. In some cases, the first and second locking mechanisms 564, 566 can then engage and help secure the side clip 286 about the arm 288 in a closed configuration.

[0117] When the material holder 280 is fully assembled, the spindle handle 294 and the side clip handle 298 can allow a user to conveniently pick up, grip, and / or install the material holder 280 into the inkjet printer 100, the thermal printer 160, the laser printer 210, or any other suitable printing device. In some cases, the spindle handle 294 and / or the side clip handle 298 can be coextensive with at least one standard observation sector 326 or at least one observation window sector 328. For example, each of the first and second flanges 282 a, 282 b can be oriented such that the spindle handle 294 can align with the standard window sector 326 or the observation window sector 328 of the first flange 282 a, and the side clip handle 298 can align with the standard window sector 326 or the observation window sector 328 of the second flange 282 b (see FIGS. 10 and 11 ). This alignment may, for example, provide greater clearance or freedom for a user's hand or fingers to grasp or otherwise manipulate material holder 280 .

[0118] The driven gear 312 of the first flange 282a (see FIG. 44A) and the driven gear 312 of the second flange 282b can be positioned outwardly relative to the media roll 340. That is, the printing device can be configured to engage the driven gear 312 of the first flange 282a and / or the driven gear 312 of the second flange 282b to drive rotation of the media roll 340, for example.

[0119] 45, the material holder 280 can be configured for use with various sizes of media rolls 340. The spindle 284 can be defined by a spindle length L measured directly and substantially parallel to the arms 288 between the end projection 452 and the keyhole region 290. The media roll 340 can be defined by a roll width W measured in a direction parallel to the axis of rotation of the media roll 340 (e.g., arms 288).

[0120] For example, the spindle length L can be at least about 160 mm, at least about 162 mm, at least about 164 mm, at least about 166 mm, at least about 168 mm, at least about 170 mm, at least about 172 mm, at least about 174 mm, at least about 176 mm, at least about 178 mm, or at least about 180 mm. The method of assembly described above with reference to Figures 44A-44D can allow the roll width W to be less than about 108 mm without requiring a similar change to the spindle length L. For example, the roll width W can be about 25.4 mm or about 50.8 mm, or any other suitable value. The positioning of the flanges 282a, 282b along the arm 288 of the spindle 284 can be adjusted to accommodate different sized media rolls 340. For example, flanges 282a and 282b may be positioned closer to one another along arm 288 when roll width W is given a value of approximately 50.8 mm than when roll width W is given a value of approximately 25.4 mm.

[0121] In other cases, the roll width W can be assigned a value of approximately 203.2 mm. In that case, the spindle length L can be assigned a value of approximately 272.6 mm. For example, the spindle length L can be assigned a value of at least approximately 262 mm, at least approximately 264 mm, at least approximately 266 mm, at least approximately 268 mm, at least approximately 270 mm, at least approximately 272 mm, at least approximately 274 mm, at least approximately 276 mm, at least approximately 278 mm, at least approximately 280 mm, or at least approximately 282 mm. Additionally, the roll width W can be assigned a value less than approximately 203.2 mm without requiring a similar change to the spindle length L. For example, the roll width W can be assigned a value of approximately 50.8 mm, approximately 108 mm, or approximately 152.4 mm, or any other suitable value, and the positioning of the flanges 282 a, 282 b along the arm 288 can be adjusted accordingly.

[0122] In still other cases, the roll width W may be approximately 254 mm. In that case, the spindle length L may be approximately 323.4 mm. For example, the spindle length L may be at least approximately 314 mm, at least approximately 316 mm, at least approximately 318 mm, at least approximately 320 mm, at least approximately 322 mm, at least approximately 324 mm, at least approximately 326 mm, at least approximately 328 mm, at least approximately 330 mm, at least approximately 332 mm, or at least approximately 334 mm. Additionally, the roll width W may be less than approximately 254 mm without requiring a similar change to the spindle length L. For example, the roll width W may be approximately 108 mm, approximately 152.4 mm, or approximately 203.2 mm, or any other suitable value, and the positioning of the flanges 282 a, 282 b along the arm 288 may be adjusted accordingly.

[0123] In one particular embodiment, the roll width W may be given a value of approximately 108 millimeters (mm), in which case the spindle length L may be given a value of approximately 171 mm.
