Description

[Technical Field]

[0001] The present invention relates to a printing system having a static elimination function for eliminating static electricity from a charged sheet, a control method thereof, and a program. [Background technology]

[0002] Recording media (hereinafter referred to as "sheets") used in printing operations carry static electricity when transported, either due to residual charge from the electrophotographic process or due to slight friction with transport rollers and guides during sheet transport. This static electricity can cause sheets to stick together. It can also cause dust and paper powder to adhere to the finished product, reducing the quality of the finished product. Plain paper and other materials have low electrical resistance, allowing charges to move easily within the sheet, and the charge itself is small, so it dissipates quickly. However, sheets made of synthetic resin (plastic), such as cardboard, synthetic paper, and coated paper, have high electrical resistance, making it difficult for charges to move within the sheet. As a result, sheets such as synthetic paper and coated paper tend to be more likely to become charged and retain a charge. It is also easily affected by the environment, especially humidity, and it is generally known that lower humidity environments reduce the amount of discharge into the air, making them more susceptible to static electricity. If post-processing is performed while sheets are stuck together, it will not only affect the sheet alignment process and reduce the quality of post-processing, but it may also induce jams due to poor paper feeding or transport during post-processing, which could damage the sheets and the equipment. Therefore, to prevent such risks, it is desirable to remove static electricity from the sheet after the printing process before post-processing is performed.Therefore, a proposal has been made to apply a voltage to a pair of transport rollers located downstream in the sheet transport direction to cancel out the charge on the sheet (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-258881 Summary of the Invention [Problem to be solved by the invention]

[0004] The conventional discharge method using a voltage applied to a transport roller (hereinafter referred to as a "discharge roller") described above neutralizes static electricity by applying a charge opposite to the charge on the sheet via the discharge roller. Therefore, the amount of discharge by the discharge roller (applying a charge opposite to that of the sheet to the discharge roller) must be set according to the amount of charge on the sheet. Furthermore, if the transport paths within the image forming apparatus are different for the double-sided printing mode and the single-sided printing mode, the charge on the sheet changes with transport, and the amount of discharge required differs for both modes. This means that there is an optimal charge adjustment value for discharge that corresponds to each printing mode. Specifically, when the static elimination amount is set to a value corresponding to the single-sided printing mode, a user may print in the double-sided printing mode without setting a charge adjustment value for static elimination in the double-sided printing mode. In this case, static elimination control is performed on the sheet with an inappropriate charge adjustment value set, which may result in the sheet becoming charged and further causing the sheet to stick. The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a mechanism that can appropriately remove static electricity according to the mode of the printing surface. [Means for solving the problem]

[0005] The present invention is a printing system having a static elimination device that can change the setting of the charge adjustment value for static elimination, and is characterized by having a first acquisition means that acquires a reference value for the charge adjustment value for static elimination that corresponds to the mode of the printing surface of a print job, and a display means that displays the reference value for the charge adjustment value for static elimination that corresponds to the mode of the printing surface acquired by the first acquisition means, and a screen that prompts a user to confirm the setting of the charge adjustment value for static elimination. [Effects of the Invention]

[0006] According to the present invention, it is possible to appropriately remove static electricity in accordance with the mode of the printing surface. [Brief explanation of the drawings]

[0008] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the following embodiments do not limit the invention according to the claims, and not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention. [Embodiment 1]

[0009] Overall system configuration FIG. 1 is a diagram showing the overall configuration of a system according to an embodiment of the present invention. The system of this embodiment includes a printing system 1000 and a PC 102 which is a client computer, which are connected to each other via a network 101 . The PC 102 is capable of transmitting PDL (Page Description Language) code data, which is a print job, to the printing system 1000 via the network 101.

[0010] Printing system hardware configuration FIG. 2 is a block diagram showing the hardware configuration of the printing system 1000. As shown in FIG. The printing system 1000 includes a printing apparatus 100 and a sheet processing apparatus 200, which are enclosed by dotted lines in the figure. Any number of sheet processing apparatuses 200 can be connected to the printing apparatus 100. In this embodiment, the sheet processing apparatus 200 is described as including a static eliminator 200-3a and a saddle stitcher 200-3b. In this embodiment, the printing apparatus 100 is described as an MFP (Multi Function Peripheral) having multiple functions, such as a copy function and a printer function. However, the printing apparatus 100 may also be a single-function printing apparatus having only a copy function or only a printer function. In this embodiment, the printing system 1000 is described as having the following components, as an example. The printing system 1000 is configured so that sheet processing for sheets printed by the printing device 100 can be performed by a sheet processing apparatus 200 connected to the printing device 100. However, it is also possible to configure the printing system 1000 using only the printing device 100 without connecting the sheet processing apparatus 200. The static eliminator 200-3a is configured to be able to communicate with the printing device 100, and can receive instructions from the printing device 100 and execute static elimination processing as described below. The static elimination operation unit 220 has a configuration as shown in FIG. 5, which will be described later, and the user can perform settings for the static elimination device 200-3a via the static elimination operation unit 220. The user may be allowed to configure the static eliminator 200-3a via a main body operation unit 204, which will be described later.

[0011] The saddle stitching machine 200-3b is configured to be able to communicate with the printing apparatus 100, and can receive instructions from the printing apparatus 100 and execute sheet processing as described below. The scanner unit 201 reads an image on a document, converts it into image data, and transfers it to other units. The external I / F 202 transmits and receives data to and from external devices connected to the network 101 . The printer unit 203 prints an image based on the input image data onto a sheet. 4, the main body operation unit 204 is configured to include a touch panel unit 401 and a hard key input unit 402, and receives instructions from the user via these. The main body operation unit 204 also displays various information on the touch panel unit 401.

[0012] The CPU 205 is a control device including a central processing unit (CPU) and controls the overall processing and operation of various units included in the printing system 1000. In other words, the CPU 205 also controls the operation of the printing apparatus 100 and the sheet processing apparatus 200 connected to the printing apparatus 100. The environmental sensor 206 is a general term for sensors that detect the installation environment, such as temperature and humidity, and in this embodiment, this refers to a temperature sensor and a humidity sensor. A typical temperature sensor is a thermistor that measures the temperature in the air. A typical humidity sensor detects the humidity in the air from changes in capacitance, and each sensor outputs an electrical signal. The CPU 205 constantly monitors the temperature and humidity of the environment in which the printing device 100 is installed, and reflects this information in the control of the printing device 100. The ROM 207 stores various computer programs executed by the CPU 205. For example, the ROM 207 stores programs for causing the CPU 205 to execute various processes in the flowcharts described below, and display control programs required to display various setting screens described below. The ROM 207 also stores a program for causing the CPU 205 to interpret PDL code data received from the PC 102 and expand it into raster image data. The ROM 207 also stores boot sequence and font information, etc. The RAM 208 stores image data and PDL code data sent from the scanner unit 201 and the external I / F 202, various programs loaded from the ROM 207, and setting information. The RAM 208 also stores information related to the sheet processing apparatus 200 (such as information related to the type and functions of the sheet processing apparatus 200 connected to the printing apparatus 100). The CPU 205 can use the information related to the sheet processing apparatus 200 stored in the RAM 208 for control.

[0013] The HDD (hard disk drive) 209 includes a hard disk and a drive unit for reading and writing data from and to the hard disk. The HDD 209 is a large-capacity storage device for storing image data input from the scanner unit 201 and compressed by the compression / decompression unit 210. The CPU 205 can print image data stored in the HDD 209 using the printer unit 203 based on user instructions. The HDD 209 also functions as a spooler, and the CPU 205 can manage PDL code data received from the PC 102 as print jobs and store them in the HDD 209. The CPU 205 can also manage print jobs stored in the HDD 209 and can obtain the number of print jobs stored and setting information for each print job. Note that other storage devices such as an SSD (solid state drive) or an eMMC (embedded multi media card) may be included instead of or in addition to the HDD. The compression / decompression unit 210 compresses and decompresses image data stored in the RAM 208 and HDD 209 using various compression methods such as JBIG and JPEG. Although details will be described later, the printing system 1000 of this embodiment is a printing system that has a static eliminator that allows the settings of the static elimination function to be changed.

[0014] FIG. 3 is a cross-sectional view of the printing apparatus 100 and the sheet processing apparatus 200 connected to the printing apparatus 100 according to the first embodiment. The sheet processing apparatus 200 of this embodiment includes a static eliminator 200-3a and a saddle stitcher 200-3b. (Printing device) First, the printing device 100 will be described. An automatic document feeder (ADF) 301 separates a stack of documents set on the loading surface of a document tray in page order, starting with the first page, and transports them onto a document glass platen for scanning by a scanner 302. The scanner 302 reads an image of an original conveyed onto a platen glass using a CCD and converts it into image data. A rotating polygon mirror (polygon mirror or the like) 303 receives a beam of light, such as a laser beam, modulated according to image data, and irradiates the beam as reflected scanning light onto a photosensitive drum 304 via a reflecting mirror. A latent image formed on photosensitive drum 304 by laser light is developed with toner, and the toner image is transferred to a sheet attached to transfer drum 305. A full-color image is formed by sequentially performing this series of image formation processes for yellow (Y), magenta (M), cyan (C), and black (K) toners. After four image formation processes, the sheet on transfer drum 305 with the full-color image formed thereon is separated by separation claw 306 and transported to fuser 308 by pre-fixing transporter 307. The fixing device 308 is made up of a combination of rollers and belts, and has a built-in heat source such as a halogen heater, and melts and fixes the toner on the sheet onto which the toner image has been transferred, using heat and pressure. The discharge flapper 309 is configured to be swingable around a swing shaft and determines the sheet transport direction. When the discharge flapper 309 swings clockwise in the figure, the sheet is transported straight and is discharged outside the machine by the discharge rollers 310.

[0015] The CPU 205 controls the printing device 100 to perform single-sided printing through the above-described sequence. On the other hand, when images are to be formed on both sides of the sheet, the discharge flapper 309 swings counterclockwise in the figure, and the sheet is changed course downward and sent to the double-sided conveying section, which includes a reversing flapper 311, a reversing roller 312, a reversing guide 313, and a double-sided tray 314. The reversing flapper 311 swings around a swing axis to determine the sheet transport direction. When processing a double-sided print job, the CPU 205 controls the printer unit 203 to swing the reversing flapper 311 counterclockwise in the figure to transport a sheet whose first side has been printed by the printer unit 203, and to feed the sheet into the reversing guide 313 via the reversing roller 312. Then, with the rear end of the sheet sandwiched between the reversing roller 312, the CPU 205 temporarily stops the reversing roller 312, and continues to swing the reversing flapper 311 clockwise in the figure. The CPU 205 also rotates the reversing roller 312 in the reverse direction. This causes the sheet to switch back and be transported, and controls the sheet to be guided to the double-sided tray 314 with the rear end and front end of the sheet swapped.

[0016] The sheets are temporarily stacked in the double-sided tray 314, and then the sheets are sent again to the registration rollers 316 by the re-feed rollers 315. At this time, the sheets are sent with the side opposite to the first-side transfer process facing the photosensitive drum. Then, in the same process as described above, the second-side image is formed on the second side of the sheet. Then, after the images are formed on both sides of the sheet, the sheet goes through a fixing process and is discharged from inside the main body of the printing apparatus 100 to the outside via the discharge rollers 310. The CPU 205 controls the printing apparatus 100 to perform double-sided printing through the above-described series of sequences. The printing device 100 also has a paper feed unit that stores sheets required for printing. The paper feed unit includes paper feed cassettes 317-318 (each capable of storing, for example, 500 sheets), paper feed deck 319 (capable of storing, for example, 5,000 sheets), and manual feed tray 320. Various sheets of different sizes and materials can be set in the paper feed cassettes 317-318 and paper feed deck 319, separated for each paper feed unit. Furthermore, various types of sheets, including special sheets such as overhead projector sheets, can be set in manual feed tray 320.

[0017] (static eliminator) Next, the static eliminator 200-3a will be described. FIG. 5 is a diagram showing the static elimination operation unit 220 of the static eliminator 200-3a. A mode setting switch 601 in FIG. 5 switches whether or not static elimination is performed by the static eliminator 200-3a (ON / OFF), and the CPU 205 controls the static elimination process, which will be described later, to be executed only when the switch is ON. In addition, the adjustment dial 602, which is configured as a thumb rotary switch, adjusts the strength of the static elimination control that is performed when the mode setting switch 601 is ON, and is controlled by the CPU 205 so that it is effective only when the mode setting switch 601 is ON.

[0018] <Static charge removal treatment> Here, the static elimination process performed by the static eliminator 200-3a will be described with reference to FIG. FIG. 6 is a diagram showing a schematic view of a state in which a static eliminator 200-3a performs static elimination processing on a sheet that has been printed by the printing apparatus 100. In FIG. First, sheet 701 is transported via transport path 710 to a developing / transferring unit consisting of photosensitive drum 304 and transfer drum 305, where toner is deposited on the sheet. The charged toner 702 on the sheet is negatively charged. After the toner is fixed through fuser 308, the sheet is transported to static elimination device 200-3a with the print surface 703 negatively charged. Static elimination device 200-3a includes positively charged static elimination roller 322, which applies a positive charge to the negatively charged print surface 703 through contact elimination, thereby eliminating the charge. However, it is expected that negative charges that are not completely removed by static elimination processing by static elimination roller 322, or reversely charged positive charges, will remain on the sheet 705 after passing through the static elimination roller. Therefore, the static elimination device 200-3a described in this embodiment is further configured to include an ionizer 323 downstream of static elimination roller 322. Ionizer 323 is a device that applies a voltage to electrode needles provided within the device to generate a corona discharge, and uses the ions thus generated to eliminate the charge. In this way, by performing rough static elimination with static elimination roller 322 and then adjusting the remaining charge with ionizer 323, sheet 707 after static elimination processing, discharged from static elimination device 200-3a, is in a state where the charge has been eliminated.

[0019] Now, let us return to the explanation using the cross-sectional view of FIG. The static eliminator 200-3a has a static eliminator roller 322 and its paired roller, and the sheet conveyed to the static eliminator 200-3a is conveyed while being sandwiched between the two rollers, and the rough static elimination is performed by the static eliminator roller 322. Thereafter, the sheet is conveyed outside the apparatus by a conveying roller 324, and the residual charge is eliminated by an ionizer 323.

[0020] (saddle stitching machine) Next, the saddle stitching machine 200-3b will be described. The sheet processing by the saddle stitching machine 200-3b includes, for example, saddle stitching, punching, cutting, shift discharge, folding, stapling, etc. Here, these jobs are called "saddle stitching jobs." When processing a saddle stitching job, the CPU 205 first transports the sheets of this job printed by the printing apparatus 100 to the saddle stitching machine 200-3b, and then causes the saddle stitching machine 200-3b to perform sheet processing for this job. The CPU 205 then stores the printed material of the saddle stitching job, which has undergone sheet processing by the saddle stitching machine 200-3b, in the paper discharge destination Z of the saddle stitching machine 200-3b. Note that there are multiple paper discharge destination candidates for the paper discharge destination Z. This is used when the saddle stitching machine 200-3b can perform multiple types of sheet processing and separates the paper discharge destinations for each sheet processing. In this embodiment, a detailed description of the transport procedure for a saddle stitching job will be omitted.

[0021] (printing process) 7 is a flowchart illustrating the printing process of the first embodiment. The process of this flowchart is realized by the CPU 205 loading a program stored in the ROM 207, HDD 209, etc. into the RAM 208 and executing it. This process is started when a print job is submitted to the printing system 1000. First, in S101, the CPU 205 of the printing device 100 interprets the print side mode setting of the submitted print job and acquires the mode information for single-sided printing or double-sided printing. The print side mode setting can be either single-sided printing mode or double-sided printing mode. Next, in S102, the CPU 205 of the printing device 100 acquires a reference value for the charge adjustment value for static elimination corresponding to the printing surface mode acquired in S101 from the charge adjustment value table 1001 (FIG. 10) stored in advance in the ROM 207. <Charge adjustment value table> FIG. 10 is a diagram showing an example of the charge adjustment value table 1001. As shown in FIG. As shown in FIG. 10, a charge adjustment value table 1001 stores a reference value 1003 of the charge adjustment value for neutralization corresponding to a mode 1002 of the printing surface. 10, for example, if the print surface mode 1002 acquired in S101 is a single-sided printing mode, the corresponding guideline value 1003 for the charge adjustment value for static elimination is 60 to 70. This value indicates the recommended range when the user sets the value using the adjustment dial 602. Next, in S103, the CPU 205 of the printing apparatus 100 displays a print start confirmation screen 901, such as the one shown in FIG. The user checks the target value of the static elimination adjustment value displayed on the print start confirmation screen 901 and adjusts the setting of the adjustment dial 602 of the static elimination device as necessary.

[0022] <Print start confirmation screen> FIG. 9 is a diagram showing a print start confirmation screen 901. On the print start confirmation screen 901, the CPU 205 of the printing apparatus 100 displays a message 902 to the user informing them that they need to check the static eliminator 200-3a, and the reference value 903 acquired in S102, prompting the user to confirm whether to continue printing. The user checks the setting of the static eliminator adjustment dial 602, changes the setting as necessary, and presses a [Continue Printing] button 904 if they wish to continue printing. The printing system 1000 is configured to allow the user to check, via such a screen, whether the static eliminator settings are appropriate for the sheet type and printing environment. Next, in S104, the CPU 205 of the printing apparatus 100 determines whether or not the CPU 205 has accepted the user's pressing of the [Continue printing] button 904 on the print start confirmation screen 901 shown in Fig. 9. If it is determined that the pressing of the [Continue printing] button 904 has not been accepted (No in S104), the CPU 205 waits until the pressing of the button is accepted. On the other hand, if it is determined that pressing of the [Continue Printing] button 904 has been accepted (Yes in S104), the CPU 205 of the printing apparatus 100 advances the process to S105. In S105, the CPU 205 of the printing device 100 resumes the printing process and executes printing.

[0023] Thereafter, in S106, the CPU 205 of the printing apparatus 100 executes a static elimination process on the sheet on which the printing process has been performed in accordance with the settings of the static elimination operation unit 220. Next, in S107, the CPU 205 of the printing device 100 determines whether the print job is complete. If the print job is not yet complete (No in S107), the CPU 205 of the printing device 100 returns the process to S105. On the other hand, if the print job is completed (Yes in S107), the CPU 205 of the printing device 100 ends the processing of this flowchart. As described above, by controlling the printing system 1000 including the discharge device 200-3a, the target value of the charge adjustment value for discharge corresponding to the mode of the printing surface and a message prompting the user to check the set value are displayed. This makes it possible to prevent situations in which static elimination is performed with an inappropriate amount of static elimination that does not match the mode of the printing surface. According to the above embodiment, printing can be performed with an appropriate amount of static elimination that matches the mode of the printing surface.

[0024] [Embodiment 2] In the first embodiment described above, a method was described in which a reference value for the charge adjustment value for static elimination corresponding to the mode of the print surface is displayed, and a warning message is displayed to prompt the user to check the charge adjustment value for static elimination. Note that in the configuration of the first embodiment, even when the charge adjustment value for static elimination is within the reference value range, a warning message may be displayed to prompt the user to check the charge adjustment value for static elimination. Therefore, in the second embodiment, when the charge adjustment value for static elimination is within the reference value range, a warning message is not displayed to prompt the user to check the charge adjustment value for static elimination.

[0025] Fig. 8 is a flowchart illustrating the printing process of the second embodiment. The process of this flowchart is realized by the CPU 205 loading a program stored in the ROM 207, HDD 209, etc. into the RAM 208 and executing it. This process is executed when a print job is submitted to the printing system 1000. Note that in Fig. 8, the same steps as in Fig. 7 are assigned the same step numbers. Below, a description of the same steps will be omitted, and only the different steps will be described. In the second embodiment, the CPU 205 of the printing apparatus 100 advances the process to S201 after processing S102. Next, in S201, the CPU 205 of the printing apparatus 100 acquires the setting value of the static elimination amount of the static elimination device 200-3a. This process is realized by the CPU 205 acquiring the setting state of the adjustment dial 602 of the static elimination operation unit 220 via the static elimination device 200-3a. Next, in S202, the CPU 205 of the printing apparatus 100 checks whether the adjustment dial setting value acquired in S201 is within the range of the reference value acquired in S102. If it is determined in S202 that the setting value is not within the range of the reference value (No in S202), the CPU 205 of the printing apparatus 100 advances the process to S103. On the other hand, if it is determined that the set value is within the range of the reference value (Yes in S202), the CPU 205 of the printing device 100 determines that there is no problem in continuing printing as is, and proceeds to S105. In other words, in this case, the CPU 205 of the printing device 100 does not display a warning to prompt confirmation of the charge adjustment value for static elimination.

[0026] According to the second embodiment, when the adjustment dial setting value in the printing process is within the target value range of the charge adjustment value for static elimination corresponding to the mode of the printing surface, the printing system 1000 including the static elimination device 200-3a is controlled so as not to confirm whether to continue the printing process. This makes it possible to display a warning message to prompt confirmation of the charge adjustment value for static elimination only when necessary. In the above embodiment, if the set value of the charge adjustment value for static elimination is outside the target value range of the charge adjustment value for static elimination, a warning is displayed. However, it is also possible to go further and have the CPU 205 automatically set an appropriate value within the target value range of the charge adjustment value for static elimination from the charge adjustment value table 1001 that corresponds to the print surface mode and sheet type. Furthermore, if the corresponding sheet or data does not exist in the charge adjustment value table 1001, a message indicating that there is no data is displayed, and data of a similar sheet type can be displayed as a reference value. Furthermore, the print process can be executed using the reference value, and the result of the static elimination process can be fed back by the user so that it can be stored in the charge adjustment value table 1001 as data for a new sheet type. According to each embodiment described above, static elimination can be performed with an appropriate charge amount corresponding to the printing surface mode. As a result, even if the printing surface mode changes, for example, the charge adjustment value for static elimination can be changed, which reduces the occurrence of a situation in which static elimination is performed with a static elimination setting that is inappropriate for the sheet. In other words, it is possible to reduce the risk of static elimination control being performed with a charge adjustment value that is inappropriate for the sheet.

[0027] (Other embodiments) It goes without saying that the configuration and contents of the various data described above are not limited to those described above, and that the data may be configured in various configurations and contents depending on the application and purpose.

Specifically, the present invention may be applied to a system consisting of multiple devices, or to an apparatus consisting of a single device. Furthermore, while the present invention has been described with reference to a static eliminator using a high-voltage application means, the present invention can also be applied to static eliminators that use a different static elimination method, such as a humidification means.
