(1-2-b) Operation Under the control of the control device 20, the multi-function device A can maintain a sleep state even if a print job is requested from a client device under a certain condition. . That is, the control device 20 can prohibit the return from the sleep state to the standby state. Further, the control device 20 can cause the printing unit 14 to execute printing exceptionally with respect to a request from a specific client device. Details are described below.

[Sleep control]
First, switching between the sleep state and the standby state in the multifunction peripheral A will be described.

  The control device 20 functions as a sleep control unit, and controls the power supply unit 15 when a job using the printing unit 14 such as printing and copying is not requested for a certain period, that is, when the printing unit 14 does not operate for a certain period. The printing unit 14 is shifted to the sleep state. This fixed period is measured by a timer (not shown).

[Return prohibition setting]
FIG. 3 is a flowchart showing the flow of setting for prohibition of return.

  As shown in FIG. 3, under the control of the control device 20, the operation panel 11 accepts an administrator login (step S101). Specifically, the control device 20 causes the display panel 111a to display a login screen including fields for inputting an ID and a password. Based on the ID and password input via this screen, the control device 20 determines whether the user who is logging in is an administrator (steps S102 and S103). That is, the control device 20 compares the input ID and password with the ID and password stored in the storage device 19. If the input ID and password and the stored ID and password match each other, it is determined that the input user is an administrator, and login is permitted (Yes in S103).

  When the login is permitted, the control device 20 displays a return prohibition instruction acceptance screen on the display panel 111a in accordance with an instruction from the administrator (S104). The control device 20 receives an instruction to prohibit the return via the return prohibition instruction screen (S105). When the return prohibition instruction is input (Yes in step S105), the control device 20 turns on the return prohibition flag (step S106). Note that the control device 20 can turn off this flag when an instruction to cancel the return prohibition is given by an operation of the administrator via the operation panel 11.

  When a return prohibition instruction is input and an authorized client device is designated by the administrator via the screen, the control device 20 sets the designated client device as an authorized client device (Yes in step S107 → S108). The permitted client device will be described later with reference to FIG.

  The control device 20 can accept “individual designation” and “batch designation” via the return prohibition instruction acceptance screen. The individual designation is designation of individual client devices, and the collective designation is designation of a plurality of client devices collectively.

  In the case of individual designation, the administrator can designate an arbitrary client device. At the time of designation, the return prohibition instruction acceptance screen may include a field for accepting direct manual input of the address of the client device, or a key for allowing the administrator to select an address in the client information storage unit 19a. Also good. Information on the client device thus designated is set as permitted client information.

  If the administrator selects batch designation, the control device 20 in the client information stored in the client information storage unit 19a is in the same area as the own device (area R1 if the multifunction device A is the multifunction device A1). The address of the client device can be set as permitted client information.

[Return control]
FIG. 4 is a flowchart showing the flow of return control.

  As shown in FIG. 4, when data is transmitted from the client device, the communication unit 12 receives the data under the control of the control device 20 (step S201). If the data sent from the client device is a request for a job, it includes job data and client information. The control device 20 analyzes the received data (step S202), and determines whether the requested job is a print job or a saved job (step S203).

  If the requested job is a save job, the control device 20 saves the received image data in a box corresponding to the address of the client device that has requested the job (step S204).

  On the other hand, if the requested job is a print job, the control device 20 determines whether the power supply by the power supply unit 15 is on or off, that is, whether the printing unit 14 is in a sleep state or a standby state. Is determined (step S205).

  If the printing unit 14 is on standby (No in step S205), the control device 20 controls the printing unit 14 to execute printout of image data (step S210).

  On the other hand, if the printing unit 14 is sleeping (Yes in step S204) and the return prohibition flag is OFF (No in step S206), the control device 20 returns the printing unit 14 to execute printing (No) (step S206). Step S206 No-> S209-> S210). Specifically, in step S209, the control device 20 controls the power supply unit 15 to supply power to the heat roller of the fixing unit, and raises the temperature of the heat roller to the fixing temperature. Then, when the heat roller reaches the fixing temperature by a temperature sensor (not shown), the control device 20 controls the printing unit 14 in step S210 to print the image data included in the data received in step S201.

  If the printing unit 14 is sleeping (Yes in step S204) and the return prohibition flag is ON (Yes in step S206), the return button 112a is pressed or the client device that has requested the job. Is a permitted client device (Yes in step S207 or S208), the control device 20 returns the printing unit 14 to execute printing (S209, S210).

  Specifically, in step S208, the control device 20 compares the client information included in the data received in step S201, that is, the information of the data transmission source (job requester) with the permitted client information. If the two match, it is determined that the client device that is the client is the permitted client device.

  If the return button 112a is not pressed and the client device that is the data transmission source is not a permitted client device (No in both steps S207 and S208), the control device 20 holds the job (step S211). That is, under the control of the control device 20, the job data is stored in a box corresponding to the client device among the boxes in the box area 19b of the storage device 19. When a box is not set for the originating client device, the control device 20 may store the job data in a box specially provided in the box area 19c for holding the job, or the box area 19c. A new box may be created and job data may be saved.

  And the control apparatus 20 controls the communication part 12, and alert | reports a preservation | save destination to the client apparatus which is a data transmission origin (step S212). That is, the control device 20 realizes a function of creating a message indicating the storage destination and a function of controlling the communication unit 12 to transmit the message. The storage destination includes the name of the multifunction device in which the job is stored, the box name in the multifunction device, and the like. The notification method is not particularly limited as long as the user can recognize the job storage destination via the display of the client device, such as e-mail or pop-up.

  The job once held (the terminal “a” in the flow) is returned to the standby state when a new job is requested after the return prohibition is canceled in the MFP A holding the job ( If the return prohibition is released even during sleep (No in step S205) (No → S209 in step S206), or if the return button 112a is pressed (Yes in step S207 → S209), the control device 20 This is executed under the control of (Step S210).

  As described above, when the MFP A is once in the sleep state under the control of the control device 20, the MFP A does not return even if a print job is requested, and keeps the surroundings of the MFP A in a quiet environment. The power consumption of the own device can be kept low.

  If the printing unit 14 does not operate for a certain period of time after printing in step S210, the control device 20 turns off the power supply by the power supply unit 15 and returns the printing unit 14 to the sleep state again. .

[Example 1]
For example, it is assumed that the MFP A1 is set to prohibit the return by the process shown in the flow of FIG.

  In this case, it is assumed that a print job is requested from the client apparatus B3 when the printing unit 14 of the multifunction peripheral A1 is in the sleep state (Yes in steps S205 and S206). At this time, if the return button 112a is not pressed, the control device 20 does not return the printing unit 14 and saves the job data in the storage device 19 (No → S211 in steps S207 and S208). The communication unit 12 notifies the client device B2 of the storage destination (step S212).

  The user who sees this notification via the display of the client device B3 approaches the side of the multifunction device A1 and presses the return button 112a to cause the multifunction device A1 to resume execution of the job once suspended. Can do.

  In addition, the multifunction peripheral A1 can accept a job designation and an instruction to cancel execution of the designated job from the user via the operation panel 11. When this instruction is given, the control device 20 can delete the designated job data from the storage device 19. Since the user can know the storage destination of the pending job by the above notification, the user can easily specify the job to be canceled.

[Example 2]
Except for the client device B1 that requested the job, under the same conditions as in the first embodiment, the control device 20 of the multifunction device A1 sends a print job to the printing unit 14 even if the return button 112a is not pressed. Execute (Yes in step S208 → S209 and S210).

  As described in the first and second embodiments, the multifunction peripheral A1 can maintain a sleep state without responding to a request from a client device installed in an area other than the area where the self-machine is provided. . Therefore, a quiet state is maintained around the multi-function device A1, and it is difficult to cause discomfort to the users in the seats around the multi-function device A1 due to sudden operation sounds.

  On the other hand, when there is a request from a client device in the same area as the multi-function peripheral A1, the user himself / herself near the multi-function peripheral A1 requests the print, so that the job is more effective than the prevention of operation sound. There is no problem even if printing is executed after canceling the sleep state, giving priority to the execution of.

  Further, if the user operates the operation panel 11 in the vicinity of the multi-function device A1, the users in the surrounding seats can recognize in advance that the operation sound is generated. Therefore, when the return button 122a is pressed, there is no problem even if the sleep state is canceled and printing is performed.

  Similarly, for copy jobs, users in the seats around the multifunction peripheral A1 can predict the generation of operation sounds. Therefore, in the first embodiment, when a copy job is requested, the control device 20 returns the printing unit 14 to execute copying even if the return is prohibited.

[2] Second Embodiment The communication system of the present embodiment has substantially the same configuration as the communication system 100 of the first embodiment, except that the flow of FIG. 5 is executed in the multifunction device A instead of the processing of FIG. It is.

  As shown in FIG. 5, the return prohibiting process of the present embodiment is the same process as FIG. 4 except that steps S311 and S312 are executed instead of steps S211 and S212.

  That is, in the present embodiment, the control device 20 controls the communication unit 12 to transfer the job to another multifunction device (step S311). More specifically, the multi-function peripheral A transmits the data received in step S301 to another multi-function peripheral, thereby causing the destination multi-function peripheral to execute printout based on this data.

  The control device 20 controls the communication unit 12 to notify the client device that is the job requester of which multifunction device the job has been transferred to (step S312). For example, if the client device that requested the job is the device B2, and the requested multifunction device is the multifunction device A1, the multifunction device A1 transfers the job to the multifunction device A2, and sends the job to the client device B2 to the multifunction device A2. Notify that the job has been transferred. The notification method and the like are as described above.

  As described above, the communication unit 12 functions as a transfer unit that transfers a job and a notification unit that notifies a client device of a job transfer destination under the control of the control device 20.

  According to the present embodiment, similar to the first embodiment, there is an advantage that the environment around the multi-function peripheral that has received the job request can be kept quiet and the printed matter can be promptly provided to the user who has requested the job. . In addition, since the job transfer destination is notified to the client device that is the requester, the user can easily grasp which multifunction device to obtain the printed matter.

[3] Other Embodiments (3-1) Printing System The MFP A according to the first and second embodiments is merely an example of a printing system. That is, the printing system may include, for example, a plurality of devices provided separately.

  For example, in the first and second embodiments, part or all of the functions performed by the control device 20 of the multifunction peripheral A may be executed by the server C. More specifically, user authentication (step S102), return prohibition setting (step S106), permitted client device setting (step S108), return permission determination (steps S206 to 208) in FIG. An instruction (step S209), job suspension (step S211), notification of the storage destination to the client device (step S212), and the like may be realized by a program of the server C.

  Further, the storage device that stores the job data when the job is suspended in step S211 in FIG. 4 is not limited to the storage device in the multifunction device, but may be a device outside the multifunction device, for example, the storage device of the server C.

(3-2) Power supply unit In addition to the configurations of the first and second embodiments, the power supply unit 15 is configured by reducing the supply amount so that the temperature of the heat roller does not rise to a sufficient level for fixing. The unit 14 may be put in a sleep state, and the heat roller may be set in a standby state by raising the temperature of the heat roller to a temperature sufficient for fixing.

(3-3) Return Prohibition Period The process of FIG. 3 may further include a step of accepting and setting a return prohibition period.

  In this case, for example, the control device 20 sets a time (for example, after 3 hours) until the return prohibition is canceled with the start of the return prohibition period as the current time, or a specific daily time period (for example, 13:00 to 15:00) Return may be prohibited, or return may be prohibited every week at a specific time zone (for example, from 13:00 to 15:00 on Monday).

(3-4) Specific Return Determination Unit In the first and second embodiments, the control device 20 functions as a specific return determination unit, and determines whether the client device falls under the permitted client device as a return condition (step S208 and S308).

  However, the specific return determination unit is not limited to this, and other conditions may be adopted as return conditions. For example, the specific return determination unit may return the printing unit 14 if the priority of the job is “high”.

(3-5) Printing apparatus In the first and second embodiments, the printing unit 14 is described as the printing apparatus. However, the printing apparatus is incorporated in the multifunction peripheral. However, the printing apparatus may be implemented as a single printer other than the multifunction peripheral.

  (3-6) The technology obtained by combining different embodiments with each other is also included in the technical scope of the present invention.
