JP 2007-30221 A

  When a user prints a plurality of sheets, the user often leaves the printing apparatus after starting printing in order to complete other tasks during printing. However, in the apparatus described in Patent Document 1, printing is stopped and printing is resumed while the user is absent, and when the user returns after all printing is finished, the user is not notified of printing stop due to vibration detection. There was a problem.

  The present invention has been made in view of the above-described problems. When the vibration of the apparatus main body exceeds a predetermined level during printing, the printing apparatus can accurately notify the user of the image printed at that time. It is another object of the present invention to provide a printing apparatus control method.

  In order to achieve the above object, the printing apparatus according to the present invention includes a printing unit that performs printing by discharging ink from a nozzle toward a recording medium, and a vibration detection unit that is provided in the apparatus main body and detects vibration of the apparatus main body. And a vibration determination unit that determines that an abnormality is detected when vibration of a predetermined level or more is detected by the vibration detection unit during printing by the printing unit. A display control means for notifying that there is an abnormality and displaying an image printed at the time of the abnormality determination on the display means is provided.

  According to the invention configured as described above, when vibration of a predetermined level or more is detected during printing and it is determined that there is an abnormality, after the printing is finished, the user is notified that there is an abnormality, and that The image printed at the time of abnormality determination is displayed on the display means. Therefore, even if the user is absent at the time of abnormality determination, the image printed at the time of abnormality determination can be accurately notified to the user.

  Further, the display unit further includes an instruction unit that instructs reprinting, and the display control unit displays a message on the display unit that prompts the user to select whether or not to reprint the image that was printed at the time of abnormality determination. When reprinting is instructed by the instruction unit, the image printed at the time of abnormality determination may be reprinted.

  According to the invention configured as described above, a message prompting the user to select whether or not to reprint an image printed at the time of abnormality determination is displayed on the display unit, and when reprinting is instructed, the image is regenerated. Since printing is performed, the user can select whether or not to perform reprinting. For example, in the apparatus described in Patent Document 1, when printing is resumed from an image printing stop position, deterioration of image quality due to vibration and printing stop is unavoidable. However, when the user desires reprinting, it is necessary to call the image again to give a print instruction, which is troublesome. On the other hand, when printing is resumed from the beginning of the image, paper and ink are wasted if the user can tolerate the degradation in image quality. Thus, according to the present invention, it is possible to improve the usability of the device by the user as compared with the device described in Patent Document 1.

  The printing unit alternately performs the relative movement of the nozzle in the main scanning direction with respect to the recording medium and the relative movement in the sub-scanning direction substantially orthogonal to the main scanning direction, while the nozzle is in the relative movement in the main scanning direction. When the display control means displays the image printed at the time of abnormality determination on the display means, the display control means determines the relative position of the nozzles at the time of abnormality determination in the sub-scanning direction. It may be displayed overlaid on the image.

  According to the invention configured as described above, when the image printed at the time of abnormality determination is displayed on the display unit, the relative position of the nozzle at the time of abnormality determination with respect to the recording medium in the sub-scanning direction is displayed superimposed on the image. Therefore, even if the user is absent during printing, the user can specify the printing position at the time of abnormality determination. Therefore, the user can accurately determine whether or not the deterioration in image quality is acceptable by examining the vicinity of the position.

  In addition, a cleaning unit that performs a nozzle cleaning process when the determination unit determines that an abnormality has occurred may be further provided. According to the invention configured as described above, when it is determined that there is an abnormality during printing, a nozzle cleaning process is performed. Therefore, even when nozzle clogging occurs due to vibration, nozzle clogging can be eliminated and printing can be performed. Can be done normally.

  Further, when it is determined that the determination unit is abnormal, a nozzle determination unit that determines whether or not the nozzle can normally eject ink, and a nozzle determination unit that determines that the nozzle cannot normally discharge ink, Cleaning means for performing a nozzle cleaning process may be further provided. According to the invention thus configured, when it is determined that there is an abnormality during printing, it is determined whether or not the nozzle can normally eject ink, and when it is determined that the nozzle cannot normally eject ink. Only the nozzle cleaning process is performed. Accordingly, there is an advantage that unnecessary cleaning processing can be avoided.

  The method of the present invention may be realized as a program executed by a computer, or may be realized as an image compression apparatus.

  The above summary of the invention does not enumerate all the necessary features of the present invention, and sub-combinations of these feature groups can also be the invention.

  An operation panel 20 is provided on the upper surface of the printer main body 12, and a cover 30 is attached to an inner side of the upper surface of the printer main body 12 so as to be freely opened and closed. The cover 30 is a resin plate formed in a size that can cover the upper surface of the printer main body 12, and exposes the surface of the operation panel 20 to the outside in the open state (see FIG. 1). On the other hand, when the cover 30 is closed, the entire operation panel 20 is covered.

  The operation panel 20 includes a display unit 22 configured by, for example, an LCD display for displaying characters, graphics, symbols, and the like, and a button group 24 arranged around the display unit 22. As shown in FIG. 2, the button group 24 includes a power button 24a for turning on / off the power, a menu button 24b for calling the main menu screen, canceling the operation in the middle, and interrupting the printing on the paper P in the middle. A cancel button 24 c for performing printing, a print button 24 d for instructing execution of printing on the paper P, a save button 24 e for saving data or the like in the memory card M inserted in the memory card slot 16, and the display unit 22. The up, down, left, and right arrow buttons 24f-24i operated when selecting a desired option from among the plurality of options displayed on the screen or moving the cursor, and the center of the up, down, left, and right arrow buttons 24f-24i An OK button for instructing that the option selected by the arrow buttons 24f to 24i is determined. 24j, a display switching button 24k for switching the screen display on the display unit 22, a left guide selection button 24l for selecting the left guide displayed on the display unit 22, and a right guide for selecting the right guide displayed on the display unit 22. A selection button 24m, a discharge tray open button 24n for opening the front door 14 having a function as a discharge tray, and the like are included.

  Further, in order to confirm the display content of the display unit 22, the cover 30 is provided with a window 32 having the same size as the display unit 22. That is, when the cover 30 is in the closed state, the user can check the display content of the display unit 22 through the window 32. On the other hand, when the cover 30 is in the open state, the display unit 22 can be adjusted to a desired angle as shown in FIG.

  Thus, when the cover 30 is in the open state, the cover 30 is held while being inclined obliquely rearward with respect to the operation panel 20 and can be used as a tray for supplying the paper P to the print mechanism unit 50. Yes. Further, at the back of the operation panel 20, a paper feed port 58 of the print mechanism unit 50 is provided, and a pair of paper guides 59 that are slid in the left-right direction so that the guide width matches the paper width are provided. Yes.

  Then, the paper P is sent to the print mechanism unit 50 through the paper feed port 58 and printing is executed. In this print mechanism section 50, as shown in FIG. 2, the timing belt 51 is looped in the left-right direction (main scanning direction X), and when the timing belt 51 is rotated by the driving of the belt roller 60, the timing belt 51 rotates. A carriage 53 fixed to the belt 51 reciprocates left and right along the guide 52. The carriage 53 is provided with a paper edge detection sensor 57 for detecting the left and right edges and the upper and lower edges of the paper P. In other words, the paper edge detection sensor 57 detects the left and right edges of the paper set in the paper supply port 58 before the printing, and allows the paper width to be recognized by detecting the right and left edges of the paper. Or detecting the trailing edge of the paper during printing to enable recognition of the paper length.

  The carriage 53 is mounted with an ink cartridge 54 that individually stores inks of each color such as cyan, magenta, yellow, and black, and a print head 55 is provided on the lower surface of the carriage 53. Each of these ink cartridges 54 is connected to a print head 55. The print head 55 applies pressure to the ink from the ink cartridge 54 and ejects the ink from the nozzles on the lower surface toward the paper P. In this embodiment, the print head 55 employs a method in which a voltage is applied to the piezoelectric element to deform the piezoelectric element and pressurize the ink. However, a voltage is applied to the heating resistor (for example, a heater) to apply the ink. You may employ | adopt the system which pressurizes ink with the bubble generated by heating. The printed paper P is transported in the sub-scanning direction Y by the transport roller 56 and sent out to the opened front door (paper discharge tray) 14. Further, a standby position of the carriage 53 that reciprocates left and right is provided at the right end. Below this standby position, a cap 61 that covers the nozzles of the print head 55 exposed on the lower surface of the carriage 53 and each nozzle of the print head 55 are provided. An ink suction mechanism 62 for sucking and discarding the thickened ink inside through the cap 61 is provided.

  Although not shown, a battery pack can be attached to the back surface of the printer main body 12, and the printer 10 can be operated by a battery without being connected to a commercial power source. Because of this point and the fact that the printer 10 is a stand-alone printer that can be used without being connected to a host computer, the printer 10 is easy to carry and can be used anywhere. Further, an acceleration sensor 80 (see FIG. 3) is provided at an appropriate position inside the printer main body 12.

  FIG. 3 is a block diagram showing the main part of the electrical configuration of the photo printer. As shown in FIG. 3, the controller 70 is configured as a microprocessor centered on the CPU 71, and includes a ROM 72 that stores various processing programs, various data, various tables, and the like, a RAM 73 that temporarily stores data, A flash memory 74 that is electrically rewritable and retains data even when the power is turned off, and a graphics memory 76 that stores data of an image to be drawn on the display unit 22 are provided via a system bus 77. They are connected so that they can exchange signals with each other. As shown in FIG. 2, an image file of a memory card M or a disk DC is input to the controller 70, a detection signal from the sensor 57 of the print mechanism unit 50, and a button group 24 of the operation panel 20. Command signal is input. The controller 70 stores images and data in the memory card M, and outputs a control signal to the print head 55 of the print mechanism unit 50 and a control signal to the display unit 22 of the operation panel 20.

  The photo printer includes an acceleration sensor 80, and the acceleration sensor 80 detects vibration applied to the photo printer. The acceleration sensor 80 detects acceleration in three directions (in this embodiment, for example, the main scanning direction X, the sub-scanning direction Y, and the vertical direction Z). A detection signal corresponding to the acceleration value in each direction is sent to the controller 70. Send it out. The cleaning mechanism 63 of the print mechanism unit 50 includes a cap 61, an ink suction mechanism 62, and the like, and cleans the nozzles of the print head 55.

A user interface (UI) input unit 701 of the CPU 71 receives various command signals based on a switch operation on the user's button group 24 and sends information necessary for other functional blocks. Based on the detection signal from the acceleration sensor 80, the acceleration determination unit 702 determines that the acceleration is abnormal when an acceleration of a predetermined level or higher is detected. The display image control unit 703 controls the display contents of the display unit 22 based on information from the UI input unit 701, data from the memory card M, and the like. The display image control unit 703 displays various messages to the user when the acceleration determination unit 702 determines that the acceleration is abnormal during execution of printing. Further, when the acceleration determination unit 702 determines that the acceleration is abnormal during printing, the display image control unit 703 notifies the user that the acceleration is abnormal after the printing is finished, and prints when the acceleration abnormality is determined. The displayed image is displayed on the display unit 22 and the user is prompted to select whether or not to reprint the image.

  The layout generation unit 704 generates layout data for printing based on information from the UI input unit 701, data from the memory card M, and the like, and sends the layout data to the print processing unit 705. The print processing unit 705 converts the layout data from the layout generation unit 704 into print data, controls the operation of the print mechanism unit 50, and executes print processing. That is, while controlling the driving of the belt roller 60 to reciprocate the carriage 53 in the main scanning direction X, the driving of the print head 55 is controlled to eject ink from the nozzles. Further, every time the forward or backward movement (pass) in the main scanning direction X of the carriage 53 is completed, the driving of the conveying roller 56 is controlled to convey the paper P by a predetermined distance in the sub-scanning direction Y. If the acceleration determination unit 702 determines that the acceleration is abnormal, the print processing unit 705 stops ink ejection from the print head 55 and stops the carriage 53 at the standby position after the end of the pass. When the layout generation unit 704 and the print processing unit 705 are instructed to reprint an image that was printed at the time of acceleration abnormality determination by an operation on the button group 24, the layout generation unit 704 and the print processing unit 705 perform control for reprinting the image.

  When the acceleration determination unit 702 determines that the acceleration is abnormal, the nozzle determination unit 706 determines whether or not ink ejection from the nozzles of the print head 55 is normal. In this embodiment, for example, manufactured by Seiko Epson Corporation. In the same manner as the automatic nozzle check system employed in the inkjet printer PX-20000, dot missing is automatically checked by voltage control.

  The cleaning control unit 707 controls the operation of the cleaning mechanism 63. When the photo printer 10 is started up or when a new ink cartridge 54 is installed, the print head 55 is capped by the cap 61 to suck ink. A nozzle cleaning process is performed by sucking ink by the mechanism 62. When the nozzle determination unit 706 determines that there is a missing dot, the cleaning control unit 707 performs a nozzle cleaning process.

  Thus, in this embodiment, the button group 24 corresponds to “instruction means” of the present invention, the acceleration sensor 80 corresponds to “vibration detection means” of the present invention, and the acceleration determination unit 702 performs “determination” of the present invention. The display image control unit 703 corresponds to the “display control unit” of the present invention, and the nozzle determination unit 706 corresponds to the “nozzle determination unit” of the present invention. The print processing unit 705 and the print mechanism unit 50 constitute a “printing unit” of the present invention, and the cleaning control unit 707 and the cleaning mechanism 63 constitute a “cleaning unit” of the present invention.

  FIG. 4 is a flowchart illustrating a printing operation procedure, and FIGS. 5 to 9 are diagrams illustrating an example of a display screen displayed on the display unit 22. In FIG. 4, when the user designates an image to be printed and the number of sheets by an operation on the button group 24 (step S10), printing is started (step S12). Then, it is determined whether or not the acceleration determination unit 702 determines that the acceleration is abnormal (step S14: determination step). If there is no acceleration abnormality determination (NO in step S14), the forward movement of the carriage 53 in the main scanning direction X or The pass count value is updated at every end of the return movement (pass) (step S16), printing is continued (step S18), and printing specified by the user at step S10 is completed (NO at step S20). Returning to step S14, the above procedure is repeated. That is, when printing on one sheet P is completed, the pass count value is reset to 0 and discharged, and when the next sheet P is fed, printing on that sheet P is started.

  On the other hand, if an acceleration abnormality determination is made during printing (YES in step S14), ink ejection is stopped after the end of the pass, the carriage 53 returns to the standby position and stops, and for example, a message shown in FIG. 5 is displayed. It is displayed on the part 22 (step S24). Then, the image currently being printed and the current pass count value are stored in the RAM 73 (step S26), and waiting while the acceleration abnormality continues (YES in step S28). When the acceleration abnormality is resolved (step S28). NO), a nozzle check is performed by the nozzle determination unit 706, and for example, a message shown in FIG. 6 is displayed on the display unit 22 (step S30).

  If the nozzle is normal (YES in step S30), the process returns to step S14 to resume printing. For example, the message shown in FIG. 7 is displayed on the display unit 22, but is not normal (step S30). NO), the nozzle cleaning process is performed, and for example, the message shown in FIG. 8 is displayed on the display unit 22 (step S34), the process returns to step S30, and the above procedure is repeated. Note that when the number of repetitions of steps S30, S32, and S34 reaches a predetermined number, a message to that effect may be displayed on the display unit 22 and the operation of the photo printer 10 may be stopped.

  When the printing designated by the user in step S10 is completed (YES in step S20), it is determined whether or not there is an acceleration abnormality during the printing (step S22). If not (NO in step S22), this routine is executed. Exit. On the other hand, if there is an abnormality in acceleration during printing (YES in step S22), based on the image and pass count value stored in step S26, for example, as shown in FIG. Is displayed, and the image 22a and the pass 22b that were printed when the acceleration abnormality occurred are displayed on the display unit 22 and a message prompting the user to select whether or not to perform reprinting is displayed (step S36: Display control process).

  When reprinting is instructed by operating the button group 24 or the like (YES in step S38), the image is reprinted and the process proceeds to step S42 (step S40). (NO in step S38), it is determined whether there is another image printed when the acceleration abnormality occurs (step S42). If there is (YES in step S42), the process returns to step S36 to If the steps are repeated but there are no others (NO in step S42), the routine is terminated.

  As described above, according to this embodiment, when it is determined that the acceleration is abnormal during printing, a message indicating that the acceleration is abnormal to the user is displayed on the display unit 22 after the printing is completed. The image 22a printed at the time of the acceleration abnormality determination is displayed. Therefore, even if the user is absent at the time of determining the acceleration abnormality, the image at the time of determining the acceleration abnormality can be accurately notified to the user.

  Further, according to this embodiment, a message that prompts the user to select whether or not to reprint the image that was printed when the acceleration abnormality is determined is displayed on the display unit 22, and reprinting is instructed by operating the button group 24. Then, since the image is reprinted, the user can easily reprint the image when the acceleration abnormality is determined. Further, when the user can tolerate a decrease in image quality, waste of paper and ink can be prevented by not performing reprinting. As a result, the usability of the photo printer 10 can be improved.

Further, according to this embodiment, when displaying the image 22a printed at the time of acceleration abnormality determination on the display unit 22, the path 22b is displayed on the image 22a based on the pass count value. Even when printing is absent, it is possible to specify the printing position when determining acceleration abnormality. Therefore, the user can accurately determine whether or not the deterioration in image quality is acceptable by examining the vicinity of the position.

  Further, according to this embodiment, if it is determined that the acceleration is abnormal during printing, the nozzle cleaning process is performed. Therefore, even when nozzle clogging occurs due to acceleration, the nozzle clogging can be eliminated, and printing can be performed. Can be done normally. Further, according to this embodiment, the nozzle check is performed by the nozzle determination unit 706, and the nozzle cleaning process is performed only when it is determined that the nozzle is not normal. There is an advantage that you can.

  The present invention is not limited to the above-described embodiment, and various modifications other than those described above can be made without departing from the spirit of the present invention. For example, in the above embodiment, the nozzle check is performed by the nozzle determination unit 706, and the nozzle cleaning process is performed only when it is determined that the nozzle is not normal. However, the present invention is not limited to this. For example, the nozzle cleaning process may be performed without performing the nozzle check. In this case, the nozzle determination unit 706 becomes unnecessary. Further, the nozzle check method of the nozzle determination unit 706 is not limited to the above embodiment, and may be performed by other methods.

  Further, in the above-described embodiment, ink ejection is stopped after the end of the pass when the acceleration abnormality is determined. Therefore, the position at the time of resuming printing can be easily specified. However, the present invention is not limited to this, and if it is determined that the acceleration is abnormal even during the pass, the ink ejection may be stopped immediately. As a result, it is possible to more reliably prevent the occurrence of printing defects. In this case, if the stop position of ink ejection in the main scanning direction X is stored in the RAM 73, the position at the time of resuming printing can be specified.

  In the above embodiment, the cleaning process is a suction process in which the ink suction mechanism 62 sucks ink from the nozzle after the print head 55 is capped by the cap 61 mainly for the purpose of discharging thickened ink and bubbles in the ink path. However, it is not limited to this. For example, the cleaning process includes a wiping process for wiping off ink adhering to the head surface with a rubber wiper, a rubbing process for wiping off ink adhering to the head surface with a sponge or the like, and a predetermined amount of ink on the cap 61 or non-printing area. A flushing process (ejection process) or the like that performs idle ejection may be used. Moreover, you may combine these. For example, the first cleaning process may be a flushing process, and the second cleaning process may be a suction process by the suction mechanism 62.

  In the above embodiment, vibration is detected by the acceleration sensor. However, sensors capable of detecting the vibration level include various types of sensors (for example, those using optical fibers and those using string vibrations). It is obvious that a configuration using a sensor other than the acceleration sensor can be included in the technical scope of the present invention.
