Description

  The present invention relates to an image forming apparatus including a display unit that displays a history of print jobs executed in the past when printed matter is lost from a paper discharge unit.

  In an office, an image forming apparatus is often shared by a plurality of users in order to reduce cost and installation area. Such an image forming apparatus accumulates prints of a plurality of users on a paper discharge tray when, for example, print jobs of a plurality of users are continuously executed.

  However, when the prints of a plurality of users are accumulated in the paper discharge tray, the user may accidentally take away the prints of other users together with his / her prints, and the prints may be lost from the paper discharge tray. At this time, there is a problem that the user who has lost the printed material has to confirm with other users in order to find the printed material, and the work is complicated.

  In view of this, an image forming apparatus that can prevent other users from taking away printed matter has been proposed (see Patent Document 1). This image forming apparatus includes a box with a cover in a paper discharge unit, and a user can designate a box for discharging printed matter. The box cover can be locked with a password. Therefore, by designating the discharge destination of the printed material for each user, only the user who has set a password can take out the printed material without mixing the printed materials of other users. Thereby, loss of printed matter can be prevented.

  However, in the image forming apparatus described in Patent Document 1, it is possible to prevent the loss of the printed material, but it is a problem in the conventional image forming apparatus, and it is complicated to confirm with the user of the image forming device when the printed material is lost. The problem has not been solved. In the image forming apparatus described in Patent Document 1, it is necessary to provide a box with a cover for the number of shared users on the side surface of the main body. For this reason, there is a problem that the apparatus is enlarged and the installation area is increased.

  SUMMARY An advantage of some aspects of the invention is that it provides an image forming apparatus that can be easily checked by the user of the image forming apparatus when the printed material is lost and does not increase in size.

  The image forming apparatus according to the present invention includes an image forming unit, a paper discharge unit, a storage unit, a display unit, and an operation unit. The image forming unit executes each print job instructed by a plurality of users, and generates a printed matter for each print job. The paper discharge unit accumulates each printed material in the order generated by the image forming unit, and the accumulated printed material can be taken out freely. The storage unit stores each print job executed by the image forming unit and the print conditions of each print job in association with each other. The display unit displays a history of each print job stored in the storage unit. The operation unit accepts selection of a lost print job in which a printed matter is lost from the paper discharge unit from the history of each print job displayed on the display unit. Further, the display unit assigns ranks to the print jobs stored in the storage unit based on the printing conditions of the lost print job that the operation unit has accepted the selection, and displays the print job history in the given ranks. Let

  In this configuration, when the user operates the operation unit and selects a lost print job in which the printed material is lost from the paper discharge unit from the print job history displayed on the display unit, the print condition of the selected lost print job is set. Are ranked and displayed. As a result, when a user's printed material is lost from the paper output unit, the print jobs that may contain the lost printed material are ranked, so by checking the display unit after operating the operation unit, Users who may have taken away can be limited. Therefore, when the printed matter is lost, it is possible to easily perform confirmation work for other users who use the image forming apparatus. In this configuration, since it is not necessary to provide a box device with a cover or the like in the image forming apparatus, the apparatus does not increase in size.

  In the above invention, the display unit displays the print jobs stored in the storage unit in descending order of the assigned order.

  In this configuration, the print jobs included in the print job history are displayed in the order of the high possibility that mixed prints are lost. Therefore, by confirming this display, it is possible to easily identify the print job that the user who has a high possibility of carrying away the lost printed matter has instructed execution.

In the above invention, the display unit, prints the image forming unit has generated is displayed at a lower rank of the print job is only one.

  When the user instructs execution of a print job with only one printed material, it is unlikely that the user will take out a plurality of printed materials from the paper discharge unit. Therefore, it is possible to prevent the user from selecting the print job by lowering the order of the print jobs.

In the above invention, the display unit displays the print job is less than the sheet size of the printed material printed matter image forming unit has generated is lost at a lower rank.

  It is difficult for the user to take out a printed material having a size larger than the printed material instructed to be generated from the paper discharge unit. Therefore, it is possible to prevent the user from selecting the print job by lowering the order of the print jobs.

In the above invention, the display unit displays the print job is printed matter on which an image forming unit has generated more than the paper size of the printed matter the lost at high have rank.

  It is considered that the user is likely to erroneously take out a printed material having the same size or a smaller size from the printed material instructed to be generated from the paper discharge unit. Therefore, it is possible to make the user select this print job by increasing the rank of this print job.

In the above invention, the display unit, the timing of the image forming unit generates the printed material is displayed last or print job is immediately after the print job prints is lost at high have rank.

  It is considered that the user is likely to erroneously take out the printed matter accumulated before and after the printed matter instructed to be generated from the paper discharge unit. Therefore, it is possible to make the user select this print job by increasing the rank of this print job.

In the above invention, the display unit, a print job that prints is lost is the same if the user is executed between two print jobs instructed to execute and display the two print jobs for high have rank.

  When the user instructs generation of two printed materials at a predetermined interval, it is highly likely that the printed material is taken out from the paper discharge unit without confirming that no other printed material is included between the two printed materials. It is done. Therefore, it is possible to make the user select these print jobs by increasing the order of these print jobs.

  In the above invention, the storage unit stores the print job printed by the image forming unit in association with the information of the terminal connected via the network and instructed to execute the print job. In addition, the control unit selects at least a part of the print jobs included in the print job history, reads out information on a terminal corresponding to the selected print job from the storage unit, and executes the print job using the terminal. A predetermined message is transmitted with the contact information of the user who has instructed the user as the destination.

  In this configuration, by selecting a print job with lost prints, a print job that may contain mixed prints is automatically selected, and a message is sent to the user who instructed the print job to be executed. To do. Therefore, when the printed matter is lost, the user's confirmation work can be simplified.

  In the above invention, the storage unit stores the print job printed by the image forming unit in association with the information of the terminal connected via the network and instructed to execute the print job. The operation unit has a function of receiving a print job selection from the print job history displayed on the display unit. The control unit reads out information on the terminal corresponding to the print job that the operation unit has accepted from the storage unit, and uses the terminal as a destination for the contact information of the user who has instructed execution of the print job as a predetermined message. Send.

  In this configuration, when the user selects a print job, a message is transmitted to the user who has instructed execution of the selected print job. Therefore, the user who has lost the printed material does not need to individually confirm with other users, and the confirmation work can be simplified.

  In the above invention, the predetermined message transmitted with the contact information of the user as a destination includes a message for confirming whether or not the printed matter has been correctly taken out from the paper discharge unit.

  In this configuration, when a printed matter is lost from the paper discharge unit, a message for confirming whether the printed matter has been correctly taken out from the paper discharge unit is sent to the user who has received the message. We can have you confirm whether you took out. Therefore, there is a high possibility that a lost printed matter can be found.

  In the above invention, the print job is a plurality of print jobs. Since a plurality of print jobs can be selected from the print job history in the operation unit, it is not necessary to repeatedly send a message, and the confirmation operation can be performed efficiently.

  In the above invention, a detection unit is provided for detecting whether or not each printed matter is accumulated in the paper discharge unit. When the operation unit accepts the selection of the lost print job, the display unit displays, based on the output of the detection unit, the print job corresponding to the printed material accumulated in the paper discharge unit before and after the lost printed material obtained by the lost print job. Extracted from the storage unit and displayed.

  With this configuration, it is possible to limit other printed materials accumulated in the paper discharge unit together with the lost printed material. Therefore, it is possible to narrow down users who may have taken away the lost printed matter.

In the above-described invention, the destination which is the contact address of the user who instructs the execution of the print job using the terminal is the user's mail address or the destination of the terminal selected by the user from the display panel .

  By sending a message by e-mail to a user who may have taken the printed material, or by displaying the message on the display screen of the terminal used by this user, the user can be sure to see the message. .

  According to the present invention, when a printed material is lost from the paper discharge unit, the lost printed material can be easily confirmed. Moreover, it can prevent that an apparatus enlarges.

  Hereinafter, an example in which the present invention is applied to a digital multifunction machine installed in an office will be described.

<Configuration of image forming system>
As shown in FIG. 1, an image forming system 100 includes a digital multifunction peripheral (hereinafter simply referred to as a multifunction peripheral) 1, N computers 2-1 to 2-N, a computer 3, an Internet fax machine 4, and a fax machine. 5 and a mobile phone 61.

  The multifunction machine 1 and the computers 2-1 to 2-N are connected to a LAN 6 installed in the office. The computer 3, Internet fax machine 4, and LAN 6 are connected to the Internet network 7. Further, the multifunction machine 1, the fax machine 5, and the mobile phone 61 are connected to the public telephone line network 8.

<Configuration of image forming apparatus>
As shown in FIGS. 2 and 3, the multi function device 1 is an in-body discharge type, and includes a panel unit 9 on the front side of the upper surface of the apparatus main body. In the multifunction device 1, unlike the image forming apparatus described in Patent Document 1, it is not necessary to install a box with a cover. The panel unit 9 includes a display unit 10 and an operation unit 11. In addition, the multifunction machine 1 includes a document transport unit 12, an image reading unit 13, an image forming unit 14, and a paper feeding unit 15 in order from the upper side to the lower side of the apparatus main body. A paper discharge unit 16 and a detection unit 17 are provided below the image reading unit 13 and the panel unit 9. The paper discharge unit 16 includes a paper discharge tray 161 that stores the printed matter generated by the image forming unit 14. In addition, the detection unit 17 includes a sensor 171 that detects the presence or absence of printed matter accumulated in the paper discharge tray 161. Furthermore, the multifunction device 1 includes a storage unit 18, an image processing unit 19, a communication unit 20, and a control unit 21 in the apparatus main body.

  As shown in FIG. 4, the display unit 10 includes a display panel 101 having a liquid crystal drive circuit and a liquid crystal panel, and a backlight unit 102 having an LED drive circuit and a plurality of LEDs for backlight.

  The operation unit 11 includes a plurality of operation buttons such as a start button 111, a numeric keypad 112, a job history button 113, a loss confirmation button 114, a returned button 115, a ranking button 116, and a function selection button 117, and a touch panel 118. .

  In the panel unit 9, a backlight unit 102, a display panel 101, and a touch panel 118 are stacked in this order.

  The multifunction device 1 is an embodiment of an image forming apparatus according to an embodiment of the present invention, and includes a print function, a copy function, and a fax function.

  The print function is a function of generating a printed matter by performing printing based on the print job received from the computers 2-1 to 2-N by the multifunction device 1.

  Each of the computers 2-1 to 2 -N has a built-in printer driver, and generates a print job for causing the multifunction device 1 to print document data and image data in accordance with a user operation. Then, the computers 2-1 to 2 -N transmit the print job to the multifunction device 1 via the LAN 6. In addition to the print data, this print job includes computer identification information such as a user ID and an IP address, and information such as various print settings.

  When the communication unit 20 receives a print job via the LAN 6, the control unit 21 of the multifunction machine 1 causes the image processing unit 19 to output image data included in the print job. Further, the control unit 21 changes the settings of the image processing unit 19 and the image forming unit 14 based on the print settings included in the print job.

  When color image data is input, the image processing unit 19 separates the color image into single color images of yellow, magenta, cyan, and black, and outputs each single color image to the image forming unit 14.

  The image forming unit 14 forms a single color toner image based on the input single color image, and generates a color toner image by superimposing the single color toner images. Then, the image forming unit 14 transfers the color toner image onto the sheet conveyed to the transfer position by the sheet feeding unit 15, and then fixes the color toner image on the sheet by the fixing unit. The paper supply unit 15 discharges a printed material, which is a sheet on which the color toner image is fixed, to a paper discharge tray 161 of the paper discharge unit 16. The paper discharge tray 161 can store a plurality of printed materials, and the user can take out the stored printed materials.

  When printing, the multifunction device 1 can specify the user who has instructed the execution of the print job from the user ID included in the print job and the IP address of the print job transmission source.

  The copy function is a function for generating a printed material by copying an original by reading an image of the original by the image reading unit 13 based on a print job received by the operation unit 11.

  When the control unit 21 detects that the operation unit 11 has received an operation for performing a copy as a print job and detects that a document is placed on the document table of the document conveying unit 12 or the image reading unit 13, Start the copy process. For example, when the operation unit 11 accepts the following operation in the operation unit 11, the control unit 21 causes the image forming unit 14 to generate a printed material under a condition according to the accepted operation.

  In the multifunction device 1, when copying, it is necessary to input a user ID first. This is because, as will be described later, when a printed matter is lost, a user who gives an instruction to execute copying is specified. The user ID can be input by a method in which the user manually operates the operation unit, or when a card in which the user ID is registered is distributed to the user in advance and is copied by a card reader (not shown). There is a method of reading.

  After the user ID is input, the control unit 21 operates the function selection button 117 to select the copy function, and then the control unit 21 operates the touch panel 118 or the numeric keypad 112 to accept the copy condition setting. Then, the received copy conditions are set in the image processing unit 19 and the image forming unit 14. When the control unit 21 receives the operation of the start button 111, the control unit 21 transports the document placed on the document transport unit 12 to the document table and moves the document to the image reading unit 13. The image reading unit 13 reads an image of a document conveyed by the document conveying unit 12 or a document placed on a document table.

  The image reading unit 13 outputs the read image data to the image processing unit 19. The multi-function device 1 performs the same process as when the print function is selected, and discharges the printed matter to the paper discharge tray 161 of the paper discharge unit 16.

  In the multi function device 1, when copying is performed, the user who instructed the execution of the print job can be specified by the user ID input first.

  The fax function is a function for transmitting and receiving image data with the Internet fax machine 4 or the fax machine 5. Of these, the present invention relates to the function of receiving image data.

  When the communication unit 20 receives fax data that is a print job transmitted from the Internet fax machine 4 or the fax machine 5, the control unit 21 outputs the fax data to the image processing unit 19. In addition to image data, the fax data includes information such as transmission source information, transmission destination (destination) information, and various print settings. The multi-function device 1 then performs the same processing as the print function, and discharges the printed matter to the paper discharge tray 161 of the paper discharge unit 16.

  In the multi function device 1, when a fax is performed, a user who has instructed execution of a print job can be specified by information on a transmission source included in the fax data or information on a transmission destination. That is, when the user name is included in the destination information, the user who has taken out the printed matter from the paper discharge tray 161 can be specified by the user name. Even if the user name is not included in the destination (destination) information, the destination (sender) from which the user receives faxes is usually limited, so the fax (printed material) depends on the source information. It is possible to identify the user who received the message. For example, if there are three users related to the fax transmission source, the number can be limited to three.

  When the multifunction device 1 receives a print job execution instruction and executes printing, copying, or faxing, the storage unit 18 stores information regarding the executed print job in the storage unit 18. The information stored in the storage unit 18 includes, for example, the type of the print job, the print job reception number, the ID of the user who instructed the execution of the print job, the date and time when the print job was executed, the number of copies, the output paper size, and the print The IP address of the device that received the job. Further, the multifunction device 1 includes IP addresses of computers 2-1 to 2-N connected to the LAN 6, IDs of users who use the computers 2-1 to 2-N, and computers 2-1 to 2-N. The information (contact address) of the terminal that notifies the user of the message of the message is registered in advance in association with each other. The storage unit 18 also stores such information. In addition, the terminal which notifies a user of a message is a terminal which a user uses normally, and should just be what can confirm a message with a character or a voice | voice. For example, computers 2-1 to 2-N may be used, and mobile devices such as the mobile phone 61 used by the user may be used.

  The terminal information (contact information) may be an email address that can be confirmed by a computer, an email address that can be confirmed by a mobile phone used by the user, a mobile phone number used by the user, or the like. When dedicated software for displaying messages is installed in the computer, the IP address of the computer may be used.

  In the multi function device 1, the control unit 21 detects whether or not prints are accumulated in the paper discharge tray 161 by the sensor 171 as described above. The control unit 21 stores the period during which the printed material is accumulated in the paper discharge tray 161 in the storage unit 18. This is to narrow down print jobs that may contain lost prints in the prints taken out from the paper discharge tray 161.

  The computers 2-1 to 2-N have the same configuration as a well-known personal computer that is generally used. The Internet fax machine 4 and the fax machine 5 have the same configuration as a well-known fax machine that is generally used. Therefore, details of these configurations are omitted.

[First Embodiment]
Next, a first embodiment of the present invention will be described. In the following description, a confirmation process when a printed material is lost from the paper discharge tray in the multifunction peripheral will be described.

  In order to facilitate the explanation of the operation of the present embodiment in a state where a plurality of user prints are accumulated in the paper discharge tray 161 of the multifunction machine 1, the types of users are distinguished as follows.

User A: The user's printed matter and the user B's printed matter were simultaneously taken out from the paper discharge tray 161 and taken out.

User B: The printed matter is actually lost from the paper discharge tray 161.

User C: One or more users. There is a suspicion that the printed matter of user B is taken out from the discharge tray 161. User C includes user A.

  When the user B comes to pick up the printed material at the installation location of the multifunction device 1 and notices that his / her printed material is lost from the paper discharge tray 161, the user B performs the following operation on the multifunction device 1. Check for lost prints.

  First, the user B operates the job history button 113 of the panel unit 9 shown in FIG. As shown in FIG. 5, when the control unit 21 detects an operation of the job history button 113 (S1: Y), the control unit 21 reads data from the storage unit 18 and displays the job history screen 201 as shown in FIG. Is displayed on the display panel 101 as the first display content (S2). Then, the control unit 21 waits for a print job to be selected (S3: N).

  The job history screen 201 shown in FIG. 6 includes, for example, a print job reception number, IDs of a plurality of users who have instructed execution of the print job, the date and time when the print job was executed, the number of printed sheets, the output paper size, and the print job. The IP address of the device that output the message, and the mail address that is the contact information of the plurality of users who instructed the print job are displayed. A loss confirmation button 202 is displayed at the lower right of the print job history screen 201.

  In addition to the user ID, a user name may be displayed. The job history screen 201 can also display the type of print job, that is, whether the print job is print, copy, or fax.

  The information displayed on these job history screens 201 serves as reference data when selecting from the job history a print job instructed to be executed by the user C who may have taken away the lost printed matter. For example, when the print job is a copy and the number of printed sheets is small, the user immediately takes out the printed material from the paper discharge tray 161 when the copying is completed without leaving the place, so it is considered that there is a low possibility that the printed material is taken away. . Further, when the print job is a print or fax and the number of printed sheets is one, there is no possibility that another user's printed matter will be taken away or very low.

  The user B touches the touch panel 118 and selects a print job by the user C who is considered to have possibly taken away the printed material from the job history screen 201. One or a plurality of print jobs may be selected.

  Note that, when the number of print jobs displayed on the job history screen 201 is small, the user B does not select a print job and print job information such as a user ID displayed on the job history screen 201. Based on the above, it is also possible to consider all the displayed users as the user C and confirm directly with the user C. In this case, the job history screen 201 can be changed to the default screen by operating the clear button.

  When the control unit 21 detects that the print job has been selected by touching the touch panel 118 (S3: Y), the control unit 21 changes the background color of the selected print job (S4, see FIG. 7A).

  Subsequently, the user B operates the loss confirmation button 202 in order to transmit a loss confirmation message to the user C instructed to execute the selected print job.

  When the control unit 21 detects the operation of the loss confirmation button 202 (S5: Y, see FIG. 7B), the control unit 21 displays a window 203 for confirming transmission of the loss confirmation message on the display panel 101 (S6, FIG. 7). (See (C)).

  When the window 203 for confirming transmission is displayed on the display panel 101, the user B operates the NO button when not transmitting a message. When the control unit 21 detects the operation of the NO button (S7: N, S8: Y), the control unit 21 performs the processing after step S2.

  On the other hand, user B operates the YES button when transmitting a message. When the control unit 21 detects the operation of the YES button (S7: Y, refer to FIG. 7D), the control unit 21 displays the user B's ID for confirming the loss in the message or displays the user B's ID to be displayed. A window 204 for confirming the ID is displayed on the display panel 101 (S9: Y, see FIG. 7E).

  When the window 204 is displayed on the display panel 101, the user B displays his / her ID in a message, and operates the YES button when the displayed ID is correct. When the control unit 21 detects the operation of the YES button (S10: Y, see FIG. 7E), the control unit 21 notifies the loss confirmation message including the ID of the user B to the user C who has instructed the execution of the selected print job. Transmit first (S13). At this time, as shown in FIG. 7F, the control unit 21 causes the display panel 101 to display a window 205 for notifying that the message transmission has been completed.

  On the other hand, when the user B does not display his / her ID in the message, the user B operates the NO button. When the control unit 21 detects the operation of the NO button (S10: N, S11: Y), the control unit 21 executes a selected print job using a loss confirmation message (hereinafter simply referred to as a message) that does not include the user B ID. The contact address of the user who has instructed is transmitted as the destination (S14).

  If the displayed ID is wrong and is changed, the change button is operated. When detecting the operation of the change button (S11: N, S12: Y), the control unit 21 displays an ID input screen (not shown) (S15: N). When the control unit 21 detects the user ID (S15: Y), the control unit 21 performs the processing after step S9 again.

  The destination to which the control unit 21 transmits the message is the mail address of the user C or the display screen of the terminals (computers 2-1 to 2-N) used by the user C.

[Email]
When the control unit 21 transmits a message to the mail address of the user C, the information on the terminals (computers 2-1 to 2-N) used by the user C who instructed execution of the print job from the storage unit 18; The mail address is read out as the contact information of the user C. And the control part 21 produces the content described below as a message, and transmits mail via the communication part 20. FIG.

  When the multifunction device 1 transmits a message by e-mail, the content (email text) as shown in FIG. 8, for example, is displayed on the terminal (monitor screen 250) of the user C who has received the e-mail. In the present embodiment, the message shown in FIG. 8A is transmitted by the control unit 21 of the multifunction peripheral (MFP) 1 as a mail transmission source.

As shown in FIG. 8A, the contents of the ID of user B (ID 1240 in the figure) are displayed.
1. There is a possibility that the printed matter of user B is mixed in the printed matter taken out from the discharge tray 161.
2. User B's identification number (ID) (a name may be substituted for ID)
3. Whether or not user B's printed materials are mixed, and that he / she wants to reply, and user B's email address,
4). If user B's printed materials are mixed, request that the user B return the printed materials directly or to the paper discharge tray 161;
Is described.

  Further, the user B ID may not be displayed. In this case, it is only necessary to notify the user B that the printed material is desired to be returned to the paper discharge tray 161.

  When the message is transmitted by e-mail, the user B can receive the response from the user C to the message by e-mail using the terminal (computers 2-1 to 2-N or the mobile phone 61) used by the user B.

[Pop-up format]
The control unit 21 transmits a loss confirmation message to the monitor screen 300 of the terminals (computers 2-1 to 2-N) used by the user C. The loss confirmation message can be displayed in a pop-up format. The pop-up format is a method in which a pop-up window is displayed on the user C's terminal and a loss confirmation message is displayed on the window.

  In order to display messages using this method, dedicated software (messenger software) for sending and receiving and displaying messages is installed in advance on the terminals used by each user (for example, computers 2-1 to 2-N, mobile phone 61). It is necessary to keep it. When any one of the computers 2-1 to 2-N is set as the transmission destination, the multi-function device 1 reads the IP address of the transmission destination from the storage unit 18, and transmits message data to this IP address. A management number is assigned to this message data.

  When each computer receives message data from the multifunction device 1, it displays a pop-up window 301 on the monitor screen 300. In this pop-up window 301, the received message is displayed.

  FIG. 8B is an example of a pop-up window. In this window 301, the same contents as in the case of mail are displayed.

  In addition to this window 301, the monitor screen 300 also displays a pop-up window 302 including two buttons (Yes button 303 and No button 304) for answering the confirmation result of mixed prints. When the control unit 21 detects that one of the two buttons 303 and 304 has been operated by the user C, the control unit 21 transmits a confirmation result of the removal (mixed) of the printed material to the multifunction device 1 and the management number. .

  The user C receiving the message confirms the printed matter taken out from the paper discharge tray 161 based on the content of the message. When the printed matter of user B is mixed, the printed matter can be returned to the paper discharge tray 161. Further, when the user ID number is described in the pop-up window, the printed matter can be returned to the user B specified based on the ID number.

  In the multi function device 1, when receiving a reply from the user C to the message transmitted by the communication unit 20 using the messenger software, the control unit 21 causes the display panel 101 to display the confirmation result. The reply to the message includes a reply indicating whether or not the user C has taken away the lost print job. The user B can confirm whether or not someone in the user C has taken away the lost printed matter on the job history screen 201 after a while after transmitting the loss confirmation message.

  When receiving the answer as described above, the control unit 21 checks which message is the answer based on the management number. And the control part 21 transmits the content of the received reply as a message using the messenger software or mail to the computer used by the user B of the ID confirmed or input in steps S13 and S15. By confirming the received message, the user B can confirm the reply to the message without moving to the installation location of the multifunction device 1.

  User B who has confirmed the reply to the message can take action according to the content of the reply. For example, in the case where the content of the answer is that it is recognized that the lost printed matter has been taken away, go to the user A who sent the answer (the user who actually took away the printed matter in user C) and return the printed matter. I can have you. Further, when none of the users C who sent the messages have taken away the printed matter, the user B can operate the operation unit 11 (touch panel 118) to send a loss confirmation message to another user. .

  As another example, in the MFP 1, when the user B selects a print job to send a message, if a specific print job to be described later is not selected in the selected print job, this A specific print job can also be automatically selected to send a message. The specific job is, for example, a print job of another user that is executed immediately before and immediately after the print job of user B (print job in which the printed matter is lost). The other user's print job is also regarded as the user C's print job, and the same processing as described above is performed. A specific job has various patterns that may be taken away, and these can be set in advance. As a modified example, when the user B does not select a print job within a predetermined time, it is possible to perform control so that the user of the specific job is automatically regarded as the user C. In addition, immediately after the user B selects a print job to send a message, the user B can also confirm the message transmission to the user of the specific job.

  Further, the user A (the user C in the user C) who has taken away the printed material may operate the returned button 115 of the operation unit 11 when returning the printed material to the paper discharge unit 16 of the multifunction machine 1. When the control unit 21 of the multifunction device 1 detects the operation of the returned button 115, the control unit 21 reads out the contact information of the user B from the storage unit 18. Then, the control unit 21 notifies that the lost printed matter has been returned by mail or messenger software with the contact information of the user B as a destination.

  The user B who has received this notification moves to the installation location of the multifunction machine 1 and can check the paper discharge unit 16 to obtain the lost printed matter.

  As another example, when the control unit 21 detects the operation of the returned button 115, the control unit 21 may transmit a message again to the user B by mail or messenger software. When the message is transmitted again, it is preferable to notify that the lost printed matter has been returned to the paper discharge unit 16.

  As another example, in the multi-function device 1, it is possible to limit the print jobs to be displayed on the history screen when the printed materials by a plurality of print jobs are accumulated in the paper discharge tray 161. In order to limit print jobs, the loss confirmation button 114 may be operated in step S1 without operating the job history button 113. For the limitation of the print job, a sensor 171 that detects the presence / absence of accumulation of printed matter in the paper discharge tray 161 is used.

  First, when the operation of the loss confirmation button 114 is detected (S1: N, S16: Y), the control unit 21 reads data of a print job that has been performed in the past from the storage unit 18 and displays it on the display panel 101 of the display unit 10. The job history screen 201 shown in FIG. 6 is displayed (S17). Since the print job executed so far is displayed on the job history screen, what is displayed is limited.

  User B touches touch panel 118 and selects a print job in which a printed matter is lost from discharge tray 161 from job history screen 201.

  When the control unit 21 detects that the touch panel 118 is touched by the user B and the selection of the print job in which the printed material is lost is received (S18: Y), the paper discharge unit is placed before and after the lost printed material obtained by the print job. The print job corresponding to the printed matter stored in 16 is extracted from the storage unit 18 based on the output of the sensor 171 and displayed (S19). The extracted print job is limited to the above. The reason for this limitation is that only the print job relating to the printed material stored together with the lost printed material is considered to be related to the loss.

  An example is shown in FIG. In the figure, the print job 5 is executed by the user B, and the printed matter by the print job is lost. Therefore, it is possible to detect from the output of the sensor 171 that the printed material accumulated together with the lost printed material is print job 3 to print job 6. As for print jobs 1 and 2, it can be seen from the output of the sensor 171 (the sensor output is turned off at 11:00) that each printed matter has been taken out. Therefore, it seems that one of the users related to the print jobs 3, 4, 6 took out the lost printed matter. Therefore, the print jobs 3, 4, and 6 are displayed as limited print jobs (S19).

  As another example, the control unit 21 extracts a print job that satisfies the printing conditions of the lost print job from the history of each print job stored in the storage unit, and displays the extracted print job as the second display content. Can be displayed on the display panel 101.

  Examples of printing conditions for lost print jobs include the following.

  1. When the print condition of the lost print job is a plurality of printed materials, a print job with only one printed material is excluded.

  When the user B prints only one printed material, it is unlikely that other users take out two or more printed materials from the paper discharge tray 161 together with other printed materials. Therefore, such print jobs are excluded.

  2. Exclude print jobs that are smaller than the paper size in the print conditions for lost print jobs.

  It is difficult for other users to take out a printed matter larger than the paper size designated by user B from the paper discharge tray 161. For example, when a user generates a B5 size printed matter, it is difficult for other users to take out the A4 size or B4 size printed matter together. Therefore, such print jobs are excluded.

  3. A print job that is equal to or smaller than the paper size in the printing conditions of the lost print job is extracted.

  It is considered that there is a high possibility that other users will take out the printed material of the paper size specified by the user B from the paper discharge tray 161. For example, when a user generates an A4 size printed matter, it is conceivable that other users take out the A4 size or B5 size printed matter together. Therefore, such a print job is extracted.

  In the present embodiment, the term “under printing conditions for lost print jobs” includes timing conditions for printing lost print jobs. Therefore, the following 4 and 5 are also set as printing conditions.

  4). A print job in which the print generation timing of the lost print job is immediately before or after the print job in which the print is lost is extracted.

  When another user takes out the printed matter stored immediately before or after the lost printed matter from the paper discharge unit 16, it is considered that the lost printed matter may be taken out by mistake. Therefore, such a print job is extracted.

  5. When a print job (user B) of a lost print is executed between two other print jobs by another same user (user C), these two print jobs are extracted in advance.

  When the user C instructs the execution of two print jobs continuously or at predetermined intervals, the print job of the user B may be sandwiched between the two depending on the timing. In such a case, it is conceivable that the user C takes out from the paper discharge tray 161 without knowing that the printed matter of the user B is sandwiched between the two printed matter. Therefore, such a print job is extracted.

  When the control unit 21 extracts a print job based on the conditions set in advance as described above, the control unit 21 displays the extracted print job on the job history screen 201 (S2). And the process after step S3 is performed.

Second Embodiment
Next, a second embodiment of the present invention will be described.

  When the user B notices that his / her printed matter has been lost from the paper discharge tray 161 of the multifunction device 1, the user B can display the other print jobs with an order as will be described below.

  First, the user B operates the ranking button 116 of the panel unit 9 shown in FIG. As shown in FIG. 10, when the control unit 21 detects the operation of the ranking button 116 (S21: Y), the control unit 21 reads data from the storage unit 18 and displays the job history screen 201 shown in FIG. Display (S22, S23: N).

  User B touches touch panel 118 and selects a lost print job from the print jobs displayed on job history screen 201 shown in FIG.

  When the control unit 21 detects that the selection of the lost print job by the user B has been received (S23: Y), the control unit 21 displays a screen for confirming whether to perform ranking based on the printing conditions of the lost print job (S24). ). When the control unit 21 detects that the user B has received an instruction to start ranking (S24: Y), the control unit 21 reads information on print jobs performed in the past from the storage unit 18, and the read print job is as follows. Then, the ranking is given (ranking) and displayed on the display panel 101. For example, the control unit 21 displays the print jobs on the display panel 101 in descending order from the highest assigned order.

  As the printing conditions for the lost print job, the five printing conditions described in the first embodiment may be used. In the present exemplary embodiment, “excluded” as a result of corresponding to the printing conditions of the lost print job in the first exemplary embodiment is assumed to be “ranked lower than other print jobs” instead. Further, in the first embodiment, “extract” as a result of satisfying the printing condition of the lost print job is assumed to be “ranked higher than other print jobs” instead.

That is,
1. When the print condition of the lost print job is a plurality of printed materials, the print job having only one printed material is ranked lower than the other print jobs.

  2. A print job that is smaller than the paper size in the print conditions of the lost print job is ranked lower than the other print jobs.

  3. A print job that is equal to or smaller than the paper size in the printing conditions of the lost print job is ranked higher than the other print jobs.

  4). The print job generation timing of the lost print job immediately before or immediately after the print job with the lost print job is ranked higher than other print jobs.

  5. If a lost print job (User B) is executed between two other print jobs by another same user (User C), the two print jobs are ranked higher than the other print jobs. .

  Also, the type of print job can be used as a condition for assigning ranks to print jobs. For example, when the print job is a copy, if the number of printed sheets is small, the user who performed the copy takes out the printed material from the paper discharge tray 161 as soon as the copying is completed without leaving the place. It is considered low. Therefore, when the print job is a copy and the number of printed sheets is a predetermined number (for example, 5 sheets) or less, the order is lower than that of printing or fax.

  As described above, when ranking print jobs based on a plurality of conditions as described above, it is preferable to weight each condition as shown in FIG. And it is good to give order | rank about each print job based on this weighted content.

  For example, when a certain print job to be ranked is one that was performed immediately before the lost print job (weight 5) and the paper size is larger than the lost print (weight 10), the weight is set to 15. . In addition, when another print job to be ranked is one immediately after the lost print job (weight 5) and the paper size is smaller than the lost print (weight 1), the weight is set to 6. To do. The control unit 21 weights the print job in this way, and displays the weight on the display panel 101 in descending order of weight (descending order).

  Note that in FIG. 11, the items whose ranking is ON indicate those used as conditions when ranking the print jobs. On the other hand, items for which ranking is OFF indicate items that are not used conditionally when ranking print jobs. Whether or not to use it under the condition can be selected by the user B by operating the operation unit 11 in advance.

  Each of the above conditions is stored in the storage unit 18, and the control unit 21 reads the conditions from the storage unit 18 and assigns ranks to the print jobs.

  In this way, by ranking the extracted print jobs, the user B selects a print job that may have a mixture of lost prints, and then instructs the user C who has instructed the execution of the print job. A message confirming the loss can be sent.

  Note that the multifunction device 1 uses the result of detecting the presence or absence of printed matter in the paper discharge tray 161 by the sensor 171 before assigning ranks to the print jobs, as described with reference to FIG. It is also possible to set so as to limit. Accordingly, the number of print jobs to be ranked can be reduced, and the ranking process can be performed in a short time.

  As shown in FIG. 10, when the ordering of print jobs is completed (S25), the control unit 21 causes the display panel 101 to display the job history screen 201 shown in FIG. 6 in descending order from the highest assigned order. (S2). Then, the control unit 21 waits for a print job to be selected (S3: N).

  As described above, by displaying the print jobs with the ranks assigned thereto, the user B can easily select the print jobs when selecting the print jobs for transmitting the message.

  When the control unit 21 detects that the print job is selected by touching the touch panel 118 (S3: Y), the control unit 21 changes the background color of the selected print job (S4). Thereafter, the control unit 21 performs each process in the same manner as in the first embodiment described with reference to FIG. 5, and transmits a message to the user C for confirming whether or not the printed material has been correctly taken out from the paper discharge tray 161.

  In addition, when the message is received by mail or messenger software, the control unit 21 performs the same processing as in the first embodiment, and transmits a predetermined message with the contact information of the user C as the destination.

  In the multi function device 1, after the control unit 21 ranks print jobs in step S25, it is automatically sent to the user C who has instructed execution of the upper print jobs (for example, the upper three print jobs). It can be set to send a message. Thereby, when a printed matter is lost, the confirmation work of the user B can be simplified.

  In step S3, when the number of print jobs displayed on the job history screen 201 is small, the user B does not select a print job, and the user ID displayed on the job history screen 201 is displayed. Based on the information of the print job, all users with the user ID can be regarded as the user C and can be directly confirmed with the user C. In this case, the job history screen 201 can be changed to the default screen by operating the clear button.

  As described above, in the multi-function device 1, even when a print job is lost when a plurality of users' print jobs are accumulated in the paper discharge tray 161, the user B who has lost the print product is It is easy for the user C to confirm the user B who has taken out the printed matter. Further, in the multi function device 1, unlike the conventional image forming apparatus, it is not necessary to provide a box with a cover. Therefore, the size of the device is not increased, and the installation area of the multi function device 1 can be suppressed.
