  [First Embodiment]

  FIG. 1 is a diagram showing an overall configuration of a color image forming apparatus according to a first embodiment of the present invention.

  Here, the image forming apparatus is the MFP 1. The MFP 1 is a multifunction device having functions such as a scanner, a copier, a printer, and a fax machine.

  The MFP 1 includes a plurality of keys 11a, an operation unit 11 that accepts input of various instructions by a user's operation on the keys, data such as characters and numbers, a display that displays an instruction menu for the user, information about an acquired image, and the like. 12. A scanner unit 13 that optically reads a document to obtain image data; a printer unit 14 that prints an image on a recording sheet based on the image data; an ADF 17 that transports paper; and a paper feed that stores paper for image formation A tray 18 and a paper discharge tray 19 are provided.

  In addition, the machine is provided with a power supply unit 16 that converts a DC power supply voltage supplied to each element from an AC power supply, and a controller unit 23 equipped with a calculation and storage function for controlling the machine.

  The display 12 provides a “live view” function that displays to the user a print image (output image) for each page synchronized with the print operation while performing a print operation. Therefore, it is desirable that the size and shape of the display 12 be such that the user can confirm the print image. Alternatively, the print image may be scroll-displayed to inform the user of the outline of the print image.

  In the “live view” function, the display 12 operates as a user interface that displays image information before printing to the user. With the “live view” function, a preview of the print image is displayed on the display 12 just before printing is performed. The preview is performed only within a predetermined period until printing is actually performed on a recording medium such as paper.

  If the user who has confirmed the preview wishes to cancel printing within the “predetermined period”, the user presses the cancel key on the operation unit 11 (or performs cancel input on the touch panel stacked on the display 12). As a result, printing of the previewed image (and / or printing of the image scheduled to be printed thereafter) is stopped.

  In this way, live view display is performed on each page of the print job between the completion of generation of image information and printing. If there is an instruction to cancel printing within a period during which printing can be canceled, printing of the page is canceled.

  By such processing, it is possible to realize a live view function for displaying an output image on each page of a printed matter while maintaining a printing operation speed that is not different from the conventional one. Further, for pages that are not intended by the user, output can be stopped for each page. In other words, by performing the live view using the period from the RIP process to the actual printing, the user's work efficiency can be improved as compared with the conventional image forming apparatus.

  FIG. 2 is a diagram showing an internal configuration of the image forming apparatus shown in FIG.

  First, a schematic configuration of the image forming apparatus will be described. The image forming apparatus includes an intermediate transfer belt 1502 as a belt member at a substantially central portion inside the image forming apparatus. The intermediate transfer belt 1502 is supported on the outer periphery of the rollers 1504 and 1505 and is driven to rotate in the direction of arrow A. The intermediate transfer belt drive roller 1505 is connected to a drive motor (not shown), and the roller 1504 is driven to rotate as the intermediate transfer belt drive roller 1505 rotates.

  Below the lower horizontal portion of the intermediate transfer belt 1502, four image forming units 1506Y, 1506M, 1506C, respectively corresponding to the respective colors of yellow (Y), magenta (M), cyan (C), and black (K), 1506K are arranged side by side along the intermediate transfer belt 1502.

  Each of the image forming units 1506Y, 1506M, 1506C, and 1506K has a photosensitive drum 1507Y, 1507M, 1507C, and 1507K, respectively. Around each of the photosensitive drums 1507Y, 1507M, 1507C, and 1507K, the photosensitive members 1508, the print head unit 1509, the developing device 1510, and the intermediate transfer belt 1502 are sandwiched in order along the rotation direction. Primary transfer rollers 1511Y, 1511M, 1511C, and 1511K facing the drums 1507Y, 1507M, 1507C, and 1507K, and a cleaner 1512 are arranged, respectively.

  A secondary transfer roller 1503 is pressed against a portion of the intermediate transfer belt 1502 supported by the intermediate transfer belt driving roller 1505, and a nip (NIP) portion between the secondary transfer roller 1503 and the intermediate transfer belt 1502 is 2 A next transfer area 1530 is formed.

  A fixing device 1520 including a heating roller 1521, a pressure roller 1522, and a magnetic flux generator 1523 is disposed at a downstream position of the conveyance path 1541 behind the secondary transfer region 1530. A pressure contact portion between the heating roller 1521 and the pressure roller 1522 is a fixing NIP region 1531.

  A paper feed cassette 1517 is detachably disposed at the lower part of the image forming apparatus. The sheets P stacked and accommodated in the sheet feeding cassette 1517 are sent out one by one from the uppermost one to the conveyance path 1540 by the rotation of the sheet feeding roller 1518.

  An AIDC (image density) sensor 1519 also serving as a registration sensor is installed between the image forming unit 1506K on the most downstream side of the intermediate transfer belt 1502 and the secondary transfer region 1530. This registration sensor 1519 measures the interval between the patterns of the respective colors formed on the intermediate transfer belt 1502 and compares the interval with a predetermined reference value to adjust the start timing of writing the image of each color. belongs to.

  Next, a schematic operation of the image forming apparatus having the above configuration will be described.

  When an image signal is input from an external device (for example, a personal computer) to an image signal processing unit (not shown) of the image forming apparatus, the image signal processing unit color-converts the image signal into yellow, cyan, magenta, and black. A digital image signal is created, and exposure is performed by causing the print head unit 1509 of each of the image forming units 1506Y, 1506M, 1506C, and 1506K to emit light based on the input digital signal. Thereby, electrostatic latent images for the respective colors are formed on the surfaces of the photosensitive drums 1507Y, 1507M, 1507C, and 1507K, respectively.

  The electrostatic latent images formed on the photosensitive drums 1507Y, 1507M, 1507C, and 1507K are respectively developed by the developing units 1510 to become toner images of the respective colors. Then, the toner images of the respective colors are primary-transferred by being sequentially superimposed on the intermediate transfer belt 1502 moving in the arrow A direction by the action of the primary transfer rollers 1511Y, 1511M, 1511C, and 1511K.

  The superimposed toner image formed on the intermediate transfer belt 1502 in this way reaches the secondary transfer region 1530 as the intermediate transfer belt 1502 moves. In the secondary transfer region 1530, the superimposed toner images are secondarily transferred to the sheet P conveyed by the timing roller 1570 by the action of the secondary transfer roller 1503.

  Next, the toner image secondarily transferred to the paper P reaches the fixing NIP area 1531. In the fixing NIP region 1531, the toner image is fixed on the paper P by the action of the heating roller 1521 and the pressure roller 1522 that generate induction heat by the magnetic flux generation unit 1523.

  The paper P on which the toner image is fixed is discharged to a paper discharge tray 19 via a paper discharge roller 1514.

  In addition, the reference position of the paper P is determined by the timing roller 1570.

  The arrangement and method of each element in FIG. 2 may be changed as appropriate according to the apparatus.

  The image forming apparatus may be a monochrome / color copying machine, a printer, a FAX, or a complex machine of these.

  FIG. 3 is a block diagram of an image processing apparatus (copy processing unit) included in the image forming apparatus of FIG.

  Referring to the figure, an image forming apparatus includes an information input unit 101 that receives an input from an operator, an information processing unit 103 that processes input information in the information input unit 101, a storage unit 105 that stores information, an image An image information generating unit 109 that generates information, a display unit 107 (corresponding to the display 12 in FIG. 1) that can display image information, an image forming unit 111 that forms an image from the image information, and An output unit 115 for printing out an image, an information reading unit 113 for reading information, an input / output interface 117 for inputting / outputting image information to / from an external device, and sheet conveyance control including control of timing rollers and the like. And a sheet conveyance control unit 119 to be performed.

  The image forming apparatus starts display of the image information on the display unit 107 and image formation from the image information, together with the completion of the generation of the image information (RIP processing completion) for each page on which the formed image is printed out. The display of the image information on the display unit 107 is performed until the print output of the formed image can be avoided. Also, the print output from the user is accepted only when the image information is being displayed.

  The information input unit 101 includes a touch panel and keys. The information processing unit 103 includes a CPU and the like. The information reading unit 113 is configured with a scanner or the like. The storage unit 105 includes a memory or the like. The image information generation unit 109 generates image information from the read information or input information. The display unit 107 includes a display 12 or a display unit of a touch panel.

  FIG. 4 is a flowchart showing an operation sequence of the image forming apparatus according to the first embodiment.

  When a PC print job is received from an external personal computer (PC) via the input / output interface 117, when a scan print job is received from a scanner, or when a print instruction is given to a job stored in the storage unit 105 When there is an instruction to start printing from the user (S101), the image information generation unit 109 performs information RIP processing. At this time, the setting screen such as the print setting is still displayed on the display unit 107.

  When the RIP process is completed for the page to be printed (YES in S103), the image information is displayed on the display unit 107 for the user (live view is performed) (S105). At the same time, the image forming unit 111 starts forming an image (S105).

  If the information processing unit 103 determines whether printing can be stopped between the start of image formation and the printing of the image and discharging, and if the page cannot be stopped, Exit the live view display and return to the print setting screen, which is the normal display screen. At the same time, printing is performed on a recording medium such as paper, and it is discharged from the output unit 115.

  In this embodiment, whether or not printing can be stopped is determined by whether or not formation of an electrostatic latent image is completed. That is, in step S107 in FIG. 4, whether electrostatic latent image formation has been completed on the photosensitive drum (if there are a plurality of photosensitive drums, electrostatic latent images on any or all of them) Whether or not the formation is completed).

  If “NO” in the step S107, it is determined whether or not there is a cancel input from the user via the information input unit 101 in a step S109, and if “NO”, the process returns to the step S107. If “YES” in the step S109, the live view display on the display unit 107 is returned to the print setting screen which is a normal display screen in a step S111, and the paper is discharged in a step S115.

  Thereafter, it is determined in step S117 whether printing of all pages of the print job has been completed. If YES, the printing process is terminated in step S119. If “NO” in the step S117, the process returns to the step S103 to perform the RIP process for the next page.

  If “YES” in the step S107, the live view display on the display unit 107 is returned to the print setting screen which is a normal display screen in step S113, and the electrostatic latent image is developed and printed. Thereafter, in step S115, the printed sheet is discharged, and the processes in and after step S117 are performed.

  In this way, in the present embodiment, the point in time at which the print output of the formed image can be avoided is the time when the image formation is completed electrostatically in the image forming unit. If the user has instructed to cancel printing by the time when printing of the formed image can be avoided, printing is stopped. As a result, it is possible to cope with the user's stop command as much as possible while performing the printing operation quickly.

  [Second Embodiment]

  Hereinafter, the difference between the image forming apparatus in the second embodiment and that in the first embodiment will be described.

  FIG. 5 is a flowchart showing an operation sequence of the image forming apparatus according to the second embodiment.

  Since the processes in steps S201 to S205 and S209 to S219 are the same as the processes in steps S101 to S105 and S109 to S119 in FIG. 4, the description here will not be repeated.

  In this embodiment, whether or not printing can be stopped is determined based on whether or not toner image formation is completed. That is, in step S207 in FIG. 5, the formation of the toner image on the photosensitive drum (or intermediate transfer belt) is completed (if there are a plurality of photosensitive drums, any one or all of the drums). Whether the toner image formation is completed or the toner image formation on the intermediate transfer belt is completed).

  If NO in step S207, the process proceeds to step S209, and if YES in step S207, the process proceeds to step S213.

  In this way, in the present embodiment, the point in time at which the print output of the formed image can be avoided is the time when the formation of the coloring material to be colored on the print medium is completed in the image forming unit. If the user has instructed to cancel printing by the time when printing of the formed image can be avoided, printing is stopped. As a result, it is possible to cope with the user's stop command as much as possible while performing the printing operation quickly.

  [Third Embodiment]

  Hereinafter, the difference between the image forming apparatus of the third embodiment and that of the first embodiment will be described.

  FIG. 6 is a flowchart showing an operation sequence of the image forming apparatus according to the third embodiment.

  Since the processes in steps S301 to S305 and S309 to S319 are the same as the processes in steps S101 to S105 and S109 to S119 in FIG. 4, the description thereof will not be repeated here.

  In this embodiment, whether or not printing can be stopped is determined based on whether or not the paper has started to pass through the timing roller 1570. That is, in step S307 in FIG. 6, it is determined whether the paper has started to pass the position of the timing roller 1570.

  If NO in step S307, the process proceeds to step S309, and if YES in step S307, the process proceeds to step S313.

  In this way, in this embodiment, the printing operation of the print medium is started in order to synchronize the formed image and the print start position of the print medium when the print output of the formed image can be avoided. The timing roller section for controlling the timing is set until the printing medium starts to pass. If the user has instructed to cancel printing by the time when printing of the formed image can be avoided, printing is stopped. As a result, it is possible to cope with the user's stop command as much as possible while performing the printing operation quickly.

  [Fourth Embodiment]

  Hereinafter, the difference between the image forming apparatus of the fourth embodiment and that of the first embodiment will be described.

  FIG. 7 is a flowchart illustrating an operation sequence of the image forming apparatus according to the fourth embodiment.

  Since the processes in steps S401 to S405, S409, S413, S417, and S419 are the same as the processes in steps S101 to S105, S109, S113, S117, and S119 in FIG. 4, the description thereof will not be repeated here.

  In this embodiment, whether or not printing can be stopped is determined by whether or not paper discharge is started. That is, in step S407 in FIG. 7, it is determined whether the output of paper from the output unit 115 is started.

  If NO in step S407, the process proceeds to step S409, and if YES in step S407, the process proceeds to step S413.

  If there is a cancel input in step S409, the printing operation is temporarily stopped in step S411. In addition, the live view display on the display unit 107 is switched to a setting screen which is a normal display screen. On the screen, the user accepts selection of whether to continue printing or cancel printing. In step S411, a page for which a printing operation has already been started is printed out.

  If the selection to cancel printing is accepted in step S411, the printing of the job is stopped there. If the selection to continue printing is accepted, the process proceeds to step S417, and the remaining pages are printed.

  In this way, in the present embodiment, the point in time at which the print output of the formed image can be avoided is the time when the output of the print medium is started from the output unit. If the user has instructed to cancel printing by the time when printing of the formed image can be avoided, printing is stopped. As a result, it is possible to cope with the user's stop command as much as possible while performing the printing operation quickly.

  [Fifth Embodiment]

  Hereinafter, the difference between the image forming apparatus of the fifth embodiment and that of the third embodiment will be described.

  FIG. 8 is a flowchart illustrating an operation sequence of the image forming apparatus according to the fifth embodiment.

  The processes in steps S501 to 509 and S513 to S519 are the same as the processes in steps S301 to 309 and S313 to S319 in FIG. 6, so the description here will not be repeated.

  In the present embodiment, when there is a stop input in step S509, the live view display on the display unit 107 is switched to the setting screen which is a normal display screen in step S511. Thereafter, the sheet is conveyed to the timing roller 1570 and waits until the next printing timing. Thereafter, the process proceeds to step S517.

  In this embodiment, if there is a stop input at a timing before the sheet passes through the timing roller, the sheet is used for printing the next page. This has the effect of saving paper.

  In this embodiment, in order to synchronize the formed image and the print start position of the print medium when the print output of the formed image can be avoided, the print operation start timing of the print medium The timing roller unit that controls the time until the printing medium starts to pass is used. If the user has instructed to cancel printing by the time when printing of the formed image can be avoided, printing is stopped. As a result, it is possible to cope with the user's stop command as much as possible while performing the printing operation quickly.

  [Others]

  When there is a cancel input, blank paper may be discharged from the output unit without printing on paper as shown in FIG. 4 to FIG. 6, or as shown in FIG. After performing the printing output, the printing operation may be temporarily stopped. Further, when the live view display is changed to the display of the normal print setting screen, the user may be requested to input whether to continue printing or end the print job as it is.

  Also, as shown in FIG. 8, when there is a cancel input, the paper that has been transported for printing may be transported to the timing roller unit, wait until the next printing timing, and used for the next printing. .

  In addition, if the information input section cancels input during the period when the page can be stopped, the live view display is changed to the normal print setting screen and whether the page has been processed. If it is determined that the process has not been completed, the image forming apparatus may be configured to proceed to the next page process.

  [Effects of the embodiment]

  As described above, the live view display operation is repeatedly performed on all pages of the print job. By displaying image information and starting image formation for each page to be printed out, the user can quickly obtain a printed output while checking the image of the output result. That is, when the user confirms the print result image, the printed matter can be output quickly while performing more accurate printing. If each page of printing is an image of a printing result not intended by the user, a printed matter is output except for the page.

  Further, as in the first embodiment, the time when printing output of each page can be stopped is until the formation of the electrostatic image (electrostatic latent image) is completed, so that coloring such as toner is performed. It becomes possible to suppress consumption of materials.

  Further, as in the second embodiment, the time point at which the print output of each page can be stopped is the completion of the formation of the toner image on the transfer belt, thereby suppressing toner consumption as much as possible. The live view display period can be extended.

  Further, as in the third embodiment, the consumption of paper or the like can be suppressed by setting the time point at which printing output of each page can be stopped until printing on a printing medium such as paper is started. It becomes possible.

  Further, as in the fourth embodiment, the point in time at which printing output of each page can be stopped is to start the output from the output unit, thereby extending the live view display period for the user. It becomes possible.

  Furthermore, if the operator inputs to cancel the print output of the page before the time at which the print output of the formed image can be avoided, the process proceeds to the process for printing the image information of the next page. As a result, the user can obtain print output at an early stage, excluding pages that have unintended output results.

  In addition, when the operator inputs to cancel the print output of the page by the time when the print output of the formed image can be avoided, the print medium is printed from the output unit without printing the formed image. , And the process shifts to a process for printing the image information of the next page, so that the user can quickly obtain a print output excluding a page that causes an output result unintended by the user. Further, the user can easily determine where the page for which the print output is stopped is located. Furthermore, since nothing is printed on the output product on which the formed image has not been printed, it can be used again as a print medium.
