JP 2003-78672 A

By the way, when causing the image processing apparatus to execute some operation, such as an operation for shifting to the power saving mode, the time from the timing start time determined according to the operation to the execution of the operation is determined for each group, not the time at which the operation is performed. When the elapsed time from the start of timing reaches the set time, the operation may be executed.
In that case, the group to which the output device belongs may be changed after the elapsed time is started. Conventionally, the problem in the case where the belonging group is changed after such elapsed time has been started has not been studied.

  In this specification, when a predetermined count value of an image processing apparatus reaches a set value set in the group to which the image processing apparatus belongs, the group is assigned after the count is started when the image processing apparatus performs an operation. Disclosed is a technique for solving the problem in the case where is changed.

  The management device disclosed in this specification is a management device that manages image processing devices in groups, and includes a communication unit that communicates with the image processing device, and a processing unit, and the processing unit includes: When the predetermined count value of the image processing apparatus reaches the set value set for the group to which the image processing apparatus belongs, the set value for causing the image processing apparatus to execute a predetermined operation is set for each group. A setting value acquisition process to be acquired; an instruction reception process for receiving a change instruction for changing the group to which the image processing apparatus belongs; and when the change instruction is received by the instruction reception process, an instruction to change the belonging group is issued by the change instruction. A change process for changing a group to which the change target apparatus belonging to the image processing apparatus is assigned, and a group to which the change target apparatus belongs by the change process. The change target device executes the operation before the count value reaches the set value set in the group to which the change target device has been changed when the time point when the change is made is the starting point of the count Execution control processing.

  According to the management apparatus, when the predetermined count value of the image processing apparatus reaches the set value set in the belonging group, the belonging group is changed after the count is started when the image processing apparatus performs an operation. The problem of the case can be solved.

In addition, in the execution control process, the processing unit changes the count value of the change target device at the time of the change to a change time count value T3, and changes the setting value set to the changed group. When the set value T2, the first determination process for determining whether or not the expression 1 is satisfied is executed, and the change point count value T3 ≧ the set value T2 after the change T1
When an affirmative determination is made by the first determination process, when the change target apparatus is caused to execute the operation when a group to which the change target apparatus belongs is changed, and a negative determination is made by the first determination process When the count value when the changed time point is the starting point of counting is referred to as a post-change count value T5, when the post-change count value T5 satisfies Equation 2, the change target device executes the operation. May be.
Changed count value T5 ≧ changed set value T2−change point count value T3 Equation 2

  According to the above management device, if the count value reaches the set value of the group after the change when the group is changed, the operation is executed when the group is changed. Can be executed. Further, when the count value does not reach the changed set value of the group, the operation is executed when Expression 2 is satisfied, so that the operation can be executed at an earlier time point.

  Further, the count value may be an elapsed time from a time measurement start time determined according to the operation, and the set value may be a set time indicating a time from the time measurement start time to the execution of the operation.

  According to the above management device, the change target device is changed to the change target device before the set time set in the group to which the change target device is changed after the time when the change target device belongs is changed. The action can be executed.

The image processing apparatus is capable of transitioning between a normal state and a power saving state, and returns to the normal state when a predetermined condition is satisfied when in the power saving state, and the operation is performed by the image processing apparatus. From the normal state to the power saving state, and the count value is an elapsed time from when the normal state is restored from the power saving state, or after the image processing apparatus has returned to the normal state. When the count is reset, it is an elapsed time since the reset, and the set value is from when the image processing apparatus last transits to the normal state to when the image processing apparatus transits to the power saving state The processing unit is configured so that the state of the change target device at the time of the change is the normal state in the execution control process. A second determination process for determining whether or not there is an elapsed time when the change target device is determined to be in the normal state by the second determination process; A third determination process for determining whether or not Expression 3 is satisfied, when the change point elapsed time T3 and the set time set in the group to which the change is made are referred to as a set time after change T2.
Elapsed time T3 ≧ set time T2 after change Eq. 3
When the affirmative determination is made by the third determination process, the change target apparatus is transitioned to the power saving state when the group to which the change target apparatus belongs is changed, while the third determination process If the elapsed time when the changed time is regarded as the starting point of timekeeping is referred to as an elapsed time after change T5, the change target device is changed when the elapsed time after change T5 satisfies Expression 4. You may make a transition to the power saving state.
Elapsed time after change T5 ≧ set time after change T2−elapsed time after change T3 Equation 4

  According to the management apparatus, when the image processing apparatus is shifted from the normal state to the power saving state, the image processing apparatus can be shifted to the power saving state at an earlier time point.

In the execution control process, the processing unit is set to the affiliation group before the change when the second determination process determines that the state of the change target device is the power saving state. When the set time is referred to as pre-change set time T1, a fourth determination process is performed to determine whether or not Expression 5 is satisfied,
Set time before change T1 ≧ Set time after change T2 Equation 5
When an affirmative determination is made by the fourth determination process, the state of the change target apparatus is maintained in the power saving state, whereas when a negative determination is made by the fourth determination process, the change target apparatus is set to the normal state. The change target device may be changed to the power saving state when the post-change elapsed time T5 satisfies Expression 6.
Elapsed time after change T5 ≧ set time after change T2−set value before change T1 Equation 6

  According to the above management device, if the current group is in a power saving state when the group is changed, if the previous normal state duration is less than the set time set for the group after the change, the normal state Can be changed to the power saving state after maintaining the set time set in the group to which the change is made.

The image processing apparatus stores the print job in the storage device when receiving the print job in which the authentication information is set, and receives an instruction to print the print job stored in the storage device. Printing is performed, and the operation is an operation of deleting, from the storage device, the print job that has not been printed within a predetermined time from when it was stored in the storage device. The value is an elapsed time from the time when the print job is stored in the storage device to the time measurement start time, and the set value is the time from when the print job is stored in the storage device until the print job is deleted. A fifth determination process in which the processing unit determines whether or not a print job is stored in the change target device in the execution control process. When an affirmative determination is made in the fifth determination process, the elapsed time at the time of the change is set as the change time elapsed time T3, and the set time set in the group to which the change is made is changed as the set time T2 after change. Then, a sixth determination process for determining whether or not Expression 7 is satisfied;
Elapsed time T3 ≧ set time T2 after change Eq. 7
If the determination result is affirmative in the sixth determination process, a selection process for controlling the change target apparatus and causing the user of the change target apparatus to select whether or not to immediately delete the print job is executed. Execution control processing, and
When a selection for immediate deletion is accepted by the selection process, the change target apparatus may be caused to execute an operation for deleting the print job at an earlier time point than when a selection not to be deleted immediately is accepted.

Generally, the secure print job is an important job, and it is not preferable to delete the secure print job immediately even if the change time elapsed time T3 reaches the post-change set time T2 when the group to which the image processing apparatus belongs is changed.
According to the above management apparatus, when the change point elapsed time T3 reaches the post-change set time T2, the user is allowed to select whether or not to delete the secure print job, so whether or not to delete the secure print job immediately. The user can select.

Further, when a negative determination is made in the sixth determination process, the control unit refers to the set time before change T1 and the set time before change when the set time set for the group before change is referred to as set time T1 before change. A seventh determination process for determining whether or not the set time T2 satisfies Expression 8;
Set time before change T1 ≧ Set time after change T2 Equation 8
When it is determined by the seventh determination process that Expression 8 is satisfied, when the elapsed time when the changed time is set as the starting point of timekeeping is referred to as changed elapsed time T5, the changed elapsed time T5 is expressed by Expression 9. While the change target device executes an operation of deleting the print job when the condition is satisfied,
Elapsed time after change T5 ≧ set time after change T2−elapsed time after change T3 Equation 9
If it is determined by the seventh determination process that Expression 8 is not satisfied, the change target apparatus may be caused to execute an operation of deleting the print job when the post-change elapsed time T5 satisfies Expression 10. .
Elapsed time after change T5 ≧ set time before change T1−elapsed time T3 change time T3 Equation 10

When a secure print job is stored, the free capacity of the storage device is reduced accordingly. Therefore, it is not desirable to store a secure print job for a long time.
According to the management apparatus, when the change time elapsed time T3 has not reached the post-change set time T2, the time obtained by subtracting the change time elapsed time T3 from the post-change set time T2 and the change time from the pre-change set time T1 Since the secure print job is deleted when the shorter one of the times obtained by reducing the elapsed time T3 is reached, it is possible to prevent the free capacity of the storage device from being reduced by the secure print job.

In addition, when a negative determination is made in the sixth determination process, the processing unit determines whether or not the free capacity of the storage device is equal to or more than a reference free capacity before executing the seventh determination process. An eighth determination process is executed. If a negative determination is made in the eighth determination process, the seventh determination process is executed. If an affirmative determination is made in the eighth determination process, the eighth determination process is executed. 7 is not executed, and the change target device may be caused to execute an operation of deleting the print job when the post-change elapsed time T5 satisfies Expression 11.
Elapsed time after change T5 ≧ set time after change T2−elapsed time after change T3 Equation 11

  According to the management device, when the free space of the storage device is equal to or larger than the reference free space, the post-change elapsed time T5 is the post-change set time T2 regardless of the size of the pre-change set time T1 and the post-change set time T2. The secure print job can be stored in the image processing apparatus until reaching the time obtained by subtracting the change point elapsed time T3.

  The image processing apparatus executes a plurality of the operations, and each of the operations has a priority of execution, and the processing unit performs the operation for each of the groups in the acquisition process. In the execution control process, if two or more of the operations are affirmed in the execution control process, the higher priority among the two or more operations is determined. The change target device may be executed first.

  According to the above management device, when a change target device is caused to execute a plurality of operations when an affiliation group is changed, an operation with a higher priority can be executed first.

  The technology disclosed in this specification can be realized in various modes such as a printing system, a management method, a management program, and a recording medium on which the management program is recorded.

  According to the above management device, when the predetermined count value of the image processing device reaches the set value set in the group to which the image processing device belongs, when the image processing device performs an operation, after the count is started It is possible to solve the problem when the belonging group is changed.

<Embodiment 1>
The first embodiment will be described with reference to FIGS.
(1) Configuration of Printing System First, a printing system 1 according to the first embodiment will be described with reference to FIG. The printing system 1 includes a plurality of image processing apparatuses 3 (3a to 3e) and a management apparatus 2 that manages them. Each image processing device 3 and the management device 2 are communicably connected via a communication network 4 such as a LAN (Local Area Network) or the Internet. The management device 2 is an example of a computer.

The plurality of image processing apparatuses 3 include a single-function printer having a print function for printing a print job received from a terminal device such as a personal computer, a single-function scanner having an image reading function for reading a document and generating image data, These include a single-function FAX apparatus having a FAX function for transmitting and receiving an image by facsimile (FAX), and a multifunction machine having a plurality of functions such as a printing function and an image reading function.
Here, an example of a multifunction machine having at least a printing function and a FAX function will be described as the image processing apparatus 3.

  The management device 2 divides a plurality of multi-function devices 3 into groups, and causes the multi-function device 3 to execute the operation when the elapsed time from the timing start time determined according to the operation reaches a set time set in the group to which the management device 2 belongs It is. The elapsed time is an example of a count value, and the set time is an example of a set value.

(2) Operation of MFP Next, the operation described above will be described. Here, as an example of the operations described above, FAX retransmission, color misregistration correction processing, output of a communication management report, transition to a power saving state, and deletion of a secure print job will be described as examples. Here, these operations will be described with operation numbers attached. In the following description, the x part of the operation x is the operation number.

(Operation 1) FAX Retransmission Fax retransmission is an operation in which, when FAX transmission fails, retransmission is attempted until transmission is successful. For example, if the transmission fails when the first FAX transmission is attempted, the multifunction device 3 sets the time when the transmission fails as the timing start time, and tries to retransmit the fax when the elapsed time from the timing start time reaches the set time. .

(Operation 2) Color misregistration correction process When a color image is printed on a recording medium, color misregistration may occur due to the misalignment between the print position of one color image and the print position of another color image. The color misregistration correction process is an operation for correcting this color misregistration.

For example, the multifunction machine 3 that prints a color image by the direct transfer tandem method prints a color misregistration correction patch for each color on a conveyance belt that conveys printing paper, and detects the patch by an optical sensor to detect the amount of color misregistration. Is detected. The multifunction device 3 corrects the color misregistration by adjusting the timing of printing the image of each color based on the detected color misregistration amount.
The multi function device 3 sets the time when the previous color misregistration correction process is executed as the timing start time, and executes the color misregistration correction process when the elapsed time from the time measurement start time reaches the set time.

  Here, although the color misregistration correction process has been described as an example of the correction process, the correction process is not limited to the color misregistration correction process. For example, density correction processing or other correction processing may be used.

(Operation 3) Outputting the Communication Management Report The communication management report is output as a communication management report such as the FAX transmission time, the FAX number of the transmission destination, the success or failure of FAX transmission, the FAX reception time, the FAX number of the transmission source. Is the action. The output of the communication management report may be performed by printing, or may be performed by sending it attached to an e-mail.
The multifunction machine 3 outputs the communication management report when the elapsed time from the timing start time reaches the set time when the previous communication management report is output.

(Operation 4) Transition to the power saving state The states of the multifunction device 3 include a normal state in which the function of the multifunction device 3 can be immediately executed, and a power saving state in which power consumption is lower than that in the normal state. The multifunction machine 3 returns to the normal state when a predetermined condition is satisfied while in the power saving state. For example, when a print job is received in the power saving state, the multifunction device 3 returns to the normal state and executes printing. The predetermined condition may be that the operation unit of the multifunction machine 3 is operated. The predetermined condition can be determined as appropriate.
The multifunction machine 3 is set to the timing start point when it returns to the normal state, and transitions to the power saving state when the elapsed time from the timing start point reaches the set time.

(Operation 5) Deletion of Secure Print Job The multifunction device 3 is configured to be able to execute secure printing. With secure printing, a user who has sent a print job from an external device such as a personal computer to the multifunction device 3 moves to the multifunction device 3 to receive the print result so that others cannot see the print result. This is a printing method.

When performing secure printing, when a user transmits a print job from an external device to the multifunction machine 3, the user sets authentication information such as a password in the print job and transmits the print job. In the following description, a print job in which authentication information is set is referred to as a secure print job.
When the multifunction device 3 receives the secure print job, the multifunction device 3 stores the received secure print job in a storage device included in the multifunction device 3, and the authentication information that matches the authentication information set in the secure print job is input. Suspend execution until

The user who has transmitted the secure print job moves to the multifunction device 3, operates the operation unit of the multifunction device 3 to select a target secure print job, and inputs authentication information set in the secure print job.
If the authentication information set in the selected secure print job matches the authentication information input by the user operating the operation unit, the multi-function device 3 executes the print job assuming that the authentication is successful. Delete the secure print job. On the other hand, if they do not match, the MFP 3 does not execute the print job because the authentication has failed.

  The multifunction machine 3 deletes the secure print job stored in the storage device without being executed even when the elapsed time from the time measurement start time reaches the set time, when the secure print job is stored. .

(3) Electrical Configuration of Management Device Next, the electrical configuration of the management device 2 will be described with reference to FIG. The management device 2 is a so-called personal computer, and includes a CPU 21, a ROM 22, a RAM 23, an operation unit 24, a display unit 25, a storage unit 26, and a network interface unit (referred to as a network I / F unit in FIG. 1) 27. .

  The CPU 21 controls each unit of the management device 2 by executing a program stored in the ROM 22 or the storage unit 26. The ROM 22 stores programs executed by the CPU 21 and various data. The RAM 23 is used as a main storage device for the CPU 21 to execute various processes. The CPU 21 is an example of a processing unit.

The operation unit 24 is hardware to which an input device 51 such as a mouse or a keyboard is connected. The input device 51 is used by a user to operate a GUI (Graphical User Interface) provided by a management program 42 described later.
The display unit 25 includes hardware to which a display device 52 such as a liquid crystal display is connected, a display driving circuit, and the like.

  The storage unit 26 is a device that stores various programs and data using a non-volatile memory such as a hard disk or a flash memory. The storage unit 26 stores an operating system (referred to as OS) 41, a management program 42, a group information table 43, a set time table 44, and the like.

  The network interface unit 27 is hardware that connects the management device 2 to the communication network 4 so as to be communicable. The network interface unit 27 is an example of a communication unit.

(4) Group Information Table and Set Time Table Next, the group information table 43 and the set time table 44 will be described with reference to FIG. Information registered in these tables is set by the user operating the GUI described above.

  In the group information table 43, identification information for identifying the multifunction device 3 and the group to which the multifunction device 3 belongs are associated and registered. The identification information may be, for example, the IP address of the multifunction device 3 or may be a name or a node number assigned to each multifunction device 3.

The user can issue a change instruction to change the group to which the multifunction machine 3 belongs by operating the GUI described above. When the management apparatus 2 receives the change instruction, the management apparatus 2 rewrites the group to which the MFP 3 is instructed by the change instruction to the group to which the change instruction is instructed.
The process in which the management apparatus 2 receives a change instruction is an example of an instruction reception process. The process in which the management apparatus 2 changes the group to which the multifunction machine 3 belongs is an example of a change process. These processes are executed when the management apparatus 2 executes the management program 42.

A set time is registered in the set time table 44 for each group and for each operation.
The multifunction device 3 inquires the management device 2 about the set time of each operation when the power is turned on. When the inquiry is made, the management device 2 transmits the set time of each operation set in the group to which the multifunction device 3 belongs to the multifunction device 3. The multifunction machine 3 counts the elapsed time from the time measurement start point determined according to the operation for each operation, and executes the operation when the set time received from the management device 2 is reached.
The management device 2 may count the elapsed time and instruct the multifunction device 3 to execute the operation when the set time is reached.

(5) Outline of Execution Control Process When the management device 2 changes the group to which the multifunction machine 3 belongs, the management apparatus 2 executes the execution control process thereafter. Here, the outline will be described.
For example, it is assumed that when an affiliation group is changed, the elapsed time before the change is discarded, and the elapsed time is started again as the time measurement start time. In this case, the operation will not be executed until the elapsed time that is the sum of the elapsed time up to the time when the group is changed and the set time set for the changed group, and the time interval for executing the operation is There is a problem of becoming longer.

Therefore, the management apparatus 2 causes the multifunction device 3 to execute an operation before the elapsed time having the time point when the belonging group is changed reaches the set time set for the changed belonging group.
Hereinafter, the operations 1 to 3, the operation 4, and the operation 5 will be described separately. In the following description, the MFP 3 whose group has been changed is referred to as a change target device.

(5-1) Operations 1 to 3 (FAX retransmission, color misregistration correction processing, communication management report output)
First, operations 1 to 3 (FAX retransmission, color misregistration correction processing, and output of a communication management report) will be described with reference to FIG.
Here, the set time set for the group before the change (first group in the figure) is the set time T1 before the change, and the set time set for the group after the change (second group in the figure) Set time T2 after change, the elapsed time from the timing start time determined according to the operation to the time when the affiliated group was changed is changed time elapsed time T3, and the elapsed time after the affiliated group change time is changed to the elapsed time starting time It is assumed to be time T5.
The change time elapsed time T3 is shorter than the pre-change set time T1. The same applies to the following operations 4 and 5.

  As described above, the elapsed time is counted for each operation in each multifunction device 3. The management device 2 acquires the elapsed time at the time of changing the belonging group from the change target device, and uses the elapsed time as the change time elapsed time T3.

(5-1-1) Case A1
Case A1 is a case where the change point elapsed time T3 is less than the post-change set time T2. For example, consider the following example.
Set time before change T1 = 10 minutes Set time after change T2 = 8 minutes Change time elapsed time T3 = 5 minutes

In this case, the management device 2 “executes the operation when the elapsed time from when the operation was last executed before the change (P1 in the drawing) reaches the set time T2 after the change (P2 in the drawing)”. The change target device is instructed. In other words, the management device 2 instructs the change target device to “execute an operation when the post-change elapsed time T5 reaches a time obtained by subtracting the change time elapsed time T3 from the post-change set time T2.”
In this way, the operation can be executed earlier by the change time elapsed time T3 than when the operation is executed at the time P3 when the post-change elapsed time T5 reaches the post-change set time T2.

  The multifunction device 3 executes the operation at the time point P2 according to an instruction from the management device 2. In this case, the multi-function device 3 sets the time point P2 as the time measurement start time, and executes the next operation when the elapsed time from the time measurement start time reaches the set time T2 after the change. In other cases to be described later, similarly, the next operation is executed using the post-change set time T2.

(5-1-2) Case A2
Case A2 is a case where the change point elapsed time T3 is equal to or longer than the post-change set time T2. For example, consider the following example.
Set time before change T1 = 10 minutes Set time after change T2 = 5 minutes Change time elapsed time T3 = 8 minutes

  In this case, the management apparatus 2 instructs the change target apparatus to immediately execute the operation when the group to which the affiliation is changed. In this way, the operation is executed earlier by the post-change set time T2 than when the post-change elapsed time T5 reaches the post-change set time T2 (P4 in the figure). Can do.

(5-2) Operation 4 (Transition to power saving state)
Next, with reference to FIG. 4, operation 4 (transition to the power saving state) will be described.

(5-2-1) Case B1
Case B1 is a case where the state of the change target device at the time of changing the belonging group is a normal state, and the change point elapsed time T3 is less than the post-change set time T2.
In this case, as in the case A1 described above, the management device 2 is changed to “change to the power saving state when the post-change elapsed time T5 reaches the time obtained by subtracting the change time elapsed time T3 from the post-change set time T2”. Instruct the target device.

(5-2-2) Case B2
Case B2 is a case where the state of the change target device at the time of changing the belonging group is a normal state, and the change time elapsed time T3 is equal to or longer than the post-change set time T2.
In this case, as in the case A2 described above, the management device 2 instructs the change target device to immediately transition to the power saving state when the group to which the change target device belongs is changed.

(5-2-3) Case B3
Case B3 is a case where the state of the change target device at the time of changing the belonging group is the power saving state, and the set time T1 before change is equal to or longer than the set time T2 after change.
In this case, the management device 2 instructs the change target device to maintain the power saving state even after changing the group to which the change target device belongs.

(5-2-4) Case B4
Case B4 is a case where the state of the device to be changed at the time of changing the belonging group is a power saving state, and the pre-change set time T1 is less than the post-change set time T2.
In this case, when the management device 2 changes the group to which it belongs, the state of the change target device is temporarily returned to the normal state. This is to add the time during which the change target device is in the previous normal state and to secure the accumulated time in the normal state until the transition to the next power saving mode for the set time T2 after the change.
Then, the management device 2 instructs the change target device to “change to the power saving state when the post-change elapsed time T5 reaches a time obtained by subtracting the post-change set time T1 from the post-change set time T2.”

(5-3) Operation 5 (Delete Secure Print Job)
Next, the operation 5 (deletion of secure print job) will be described with reference to FIGS.

(5-3-1) Cases C1 (a) and C1 (b)
Cases C1 (a) and C1 (b) are cases where the change point elapsed time T3 is equal to or longer than the post-change set time T2.
Generally, the secure print job is an important job, and it is not preferable to delete the secure print job immediately even if the change time elapsed time T3 reaches the post-change set time T2 when the group is changed. Therefore, when the change time elapsed time T3 reaches the post-change set time T2, the management apparatus 2 instructs the change target apparatus to inquire the user whether or not to delete the secure print job immediately.

When the above-described instruction is given, the change target apparatus instructs the printer driver executed by the external apparatus that has transmitted the secure print job to the change target apparatus to display a selection screen for accepting the above selection.
The printer driver displays a selection screen according to the instruction and accepts the selection from the user. Then, the printer driver transmits the selection result to the multifunction device 3. The multifunction device 3 transmits the selection result received from the printer driver to the management device 2.

  The management apparatus 2 determines the user's selection from the selection result, and if the selection is to delete immediately, the management apparatus 2 instructs the change target apparatus to immediately delete the secure print job, as shown in case C1 (a). On the other hand, if it is selected not to delete immediately, the management apparatus 2 deletes the secure print job when the post-change elapsed time T5 reaches the post-change set time T2, as shown in case C1 (b). To the change target device.

  In case C1 (b), the post-change elapsed time T5 may be deleted before reaching the post-change set time T2. For example, if the pre-change set time T1 is greater than the post-change set time T2, the post-change elapsed time T5 may be deleted when the post-change set time T2 is subtracted from the pre-change set time T1. .

(5-3-2) Case C2
A case C2 illustrated in FIG. 6 is a case where the change time elapsed time T3 is less than the post-change set time T2, and the free space of the storage device of the change target device is greater than or equal to the reference free space.
When the free space is equal to or larger than the reference free space, the management apparatus 2 “deletes the secure print job when the post-change elapsed time T5 reaches the time obtained by subtracting the post-change time T3 from the post-change set time T2.” The change target device is instructed.

(5-3-3) Cases C3 (a) and C3 (b)
Cases C3 (a) and C3 (b) are cases where the change point elapsed time T3 is less than the post-change set time T2 and the free space of the storage device is less than the reference free space.
When the secure print job is stored, the free capacity of the storage device is reduced by that amount. Therefore, if the free capacity is less than the reference free capacity, it is not desirable to store the secure print job for a long time.

  Therefore, the management device 2 has reached the shorter one of the time obtained by subtracting the change time elapsed time T3 from the post-change setting time T2 and the time obtained by subtracting the change time elapsed time T3 from the pre-change time T3. Sometimes, the change target apparatus is caused to delete the secure print job.

  Case C3 (a) is a case where the pre-change set time T1 is equal to or greater than the post-change set time T2. In this case, the management apparatus 2 instructs the change target apparatus to “delete the secure print job when the post-change elapsed time T5 reaches a time obtained by subtracting the change time elapsed time T3 from the post-change set time T2.”

  Case C3 (b) is a case where the pre-change set time T1 is less than the post-change set time T2. In this case, the management apparatus 2 instructs the change target apparatus to “delete the secure print job when the post-change elapsed time T5 reaches the time obtained by subtracting the change time elapsed time T3 from the pre-change set time T1”.

In S107, the management program 42 determines whether or not the current state of the change target device is a normal state. If it is a normal state, the process proceeds to S108, and if it is a power saving state, the process proceeds to S109. S107 is an example of a second determination process.
In S108, the management program 42 executes an execution control process according to operations 1 to 3 and operation 4 (normal state). Execution control processing according to operations 1 to 3 and operation 4 (normal state) will be described later.

In S109, the management program 42 executes an execution control process according to operation 4 (power saving state). The execution control process according to operation 4 (power saving state) will be described later.
In S110, the management program 42 executes an execution control process corresponding to the operation 5. The execution control process corresponding to the operation 5 will be described later.
S108, S109, and S110 are examples of execution control processes.

In S111, the management program 42 notifies the change target device of the operation set time of the operation number M set in the group to which the change has been made. Thereafter, the change target device executes the operation of the operation number M according to the set time.
In S112, the management program 42 determines whether or not the operation number M is equal to the operation number N. If the operation number M is equal, the process is terminated. If not, the process returns to S104 to repeat the process.

(6-1) Execution control processing according to operations 1 to 3 and operation 4 (normal state) Next, referring to FIG. 8, operations 1 to 3 and operation 4 (normal operation executed in S108) The execution control process according to the (state) will be described.

In S201, the management program 42 determines whether or not the change time elapsed time T3 satisfies the following Expression 3. If satisfied, the process proceeds to S202, and if not satisfied, the process proceeds to S203. S201 is an example of a first determination process and a third determination process.

Elapsed time after change T5 = set time after change T2−elapsed time after change T3 Equation 4

(6-2) Execution Control Process According to Operation 4 (Power Saving State) Next, the execution control process according to the operation 4 (power saving state) executed in S109 will be described with reference to FIG.

In S301, the management program 42 determines whether or not the pre-change setting time T1 satisfies the following expression 5. If not, the process proceeds to S302. If satisfied, the process returns to the execution control process. S301 is an example of a fourth determination process.

In S302, the management program 42 instructs the change target device to return to the normal state.

In S303, the management program 42 instructs the change target device to transition to the power saving state when the post-change elapsed time T5 satisfies the following Expression 6.
Elapsed time after change T5 = set time after change T2−set time before change T1.

(6-3) Execution Control Process According to Operation 5 Next, the execution control process according to the operation 5 executed in S110 will be described with reference to FIG.
Here, it is assumed that the change target device is managed by assigning a job number (integer value) starting from 1 to the secure print job. For example, when a secure print job with job number 3 is executed, the job numbers after job number 4 are incremented. However, in order to facilitate understanding, it is assumed that the job number is not incremented during execution of this processing.

In S401, the management program 42 sets 1 as an initial value to the job number J which is a variable for counting the job number.
In S402, the management program 42 determines whether a secure print job with the job number J is stored in the change target device. If it is stored, the process proceeds to S403, and if not stored, the process returns to the execution control process. . S402 is an example of a fifth determination process.

In step S403, the management program 42 determines that the change point elapsed time T3, which is the elapsed time from when the secure print job with the job number J is stored in the change target device to when the change of the affiliated group is instructed, It is determined whether or not the condition is satisfied. If Expression 7 is satisfied, the process proceeds to S404. Otherwise, the process proceeds to S408. S403 is an example of a sixth determination process.
Elapsed time T3 ≧ set time T2 after change Eq. 7

In S <b> 404, the management program 42 causes the change target apparatus to execute a process of inquiring the user whether to delete the secure print job with the job number J immediately. S404 is an example of a selection process execution control process.
In S405, the management program 42 determines whether or not the user has selected to delete immediately. If the user selects to delete immediately, the process proceeds to S406. If the user selects not to delete immediately, the process proceeds to S407.

In S406, the management program 42 instructs the change target device to immediately delete the secure print job with the job number J.
In S407, the management program 42 instructs the change target device to delete the secure print job with the job number J when the post-change elapsed time T5 reaches the post-change set time T2.

In S408, the management program 42 executes a deletion process when T3 <T2. Deletion processing when T3 <T2 will be described later.
In S409, the management program 42 adds 1 to the job number J and returns to S402.

(6-4) Deletion Process When T3 <T2 Next, the deletion process when T3 <T2 executed in S408 will be described with reference to FIG.

  In S501, the management program 42 determines whether or not the free capacity of the storage device of the change target apparatus is less than the reference free capacity. If it is less than the reference free capacity, the process proceeds to S502. The process proceeds to S505. S501 is an example of an eighth determination process.

In S502, the management program 42 determines whether or not the pre-change setting time T1 and the post-change setting time T2 satisfy the following Expression 8, and if so, the process proceeds to S503, and if not, the process proceeds to S504. S502 is an example of a seventh determination process.
Set time before change T1 ≧ Set time after change T2 Equation 8

In S503, the management program 42 instructs the change target device to delete the secure print job with the job number J when the post-change elapsed time T5 satisfies the following Expression 9.
Elapsed time after change T5 = set time after change T2−elapsed time after change T3 Equation 9

In S504, the management program 42 instructs the change target device to delete the secure print job with the job number J when the post-change elapsed time T5 satisfies the following Expression 10.
Elapsed time after change T5 = set time before change T1−elapsed time T3 change time T3 Equation 10

In S505, the management program 42 instructs the change target device to delete the secure print job with the job number J when the post-change elapsed time T5 satisfies the following Expression 11.
Elapsed time after change T5 = set time after change T2−elapsed time after change T3 Equation 11

(7) Effects of the embodiment According to the management device 2 described above, the elapsed time with the time when the group to which the change target device belongs is changed as the time measurement start time is set to the group to which the change target device has been changed. Before the set time is reached, the change target device is caused to perform an operation. For this reason, the time interval for executing the operation should be shortened compared to the case where the operation is executed when the elapsed time from the change of the belonging group reaches the set time set for the new group. Can do.
Therefore, according to the management apparatus 2, when the elapsed time reaches the set time set in the group, the problem is solved when the group is changed after the time measurement is started when the multifunction device 3 performs an operation. can do.

  Furthermore, according to the management device 2, in the case of the operation 4 (transition to the power saving state), it is possible to make the transition to the power saving state at an earlier time point than in the case described above.

  Further, according to the management device 2, when the group is in the power saving state when the group is changed, if the pre-change setting time T1 is less than the post-change setting time T2, the normal state is changed to the post-change setting time T2. After maintaining the above, the power saving state can be entered.

  Further, according to the management apparatus 2, in the case of operation 5 (deletion of secure print job), when the change time elapsed time T3 reaches the set time T2 after change, the user determines whether or not to delete the secure print job immediately. Therefore, the user can select whether to delete the secure print job immediately.

  Further, according to the management device 2, when the change time elapsed time T3 has not reached the post-change set time T2, the time obtained by subtracting the change time elapsed time T3 from the post-change set time T2 and the pre-change set time T1 Since the secure print job is deleted when the shorter one of the times obtained by subtracting the change point elapsed time T3 is reached, it is possible to prevent the free space of the storage device from being reduced by the secure print job.

  Further, according to the management device 2, when the free space of the storage device is equal to or larger than the reference free space, the post-change elapsed time T5 is set after the change regardless of the size of the pre-change set time T1 and the post-change set time T2. The secure print job can be stored in the multi-function device 3 until reaching the time obtained by subtracting the change time elapsed time T3 from the time T2.

  Further, according to the management device 2, since the execution control process sequentially determines from the operation number 1, when the group to be changed is changed, when the change target device immediately executes a plurality of operations, the operation with the smaller operation number is started. To be executed. That is, the operation number is a priority set for the operation, and an operation with a higher priority, in other words, an operation with a lower operation number can be executed first.

<Embodiment 2>
Next, Embodiment 2 will be described with reference to FIG.
With reference to FIG. 12, the operation | movement 4 (transition to a power saving state) which concerns on Embodiment 2 is demonstrated. The multifunction device 3 according to the second embodiment resets the elapsed time to 0 when any function is executed or an operation is performed during the normal state.

  For example, when a print job is received and printing is performed in the normal state, the elapsed time is reset to 0 when printing is completed. That is, the multi-function device 3 is set to the timing start point whenever the elapsed time is reset, and transitions to the power saving state when the elapsed time after the reset reaches the set time. Therefore, the change point elapsed time T3 of the present embodiment is an elapsed time from when the elapsed time is reset to when the belonging group is changed.

  Case D1 is a case where the state of the change target device at the time of changing the belonging group is a normal state, and the change time elapsed time T3 that is reset to 0 at least once before changing the belonging group is This is a case where the post-change set time is less than T2. In this case, as in the case B1 described above, the management device 2 makes a transition to the power saving state when the post-change elapsed time T5 reaches the time obtained by subtracting the post-change elapsed time T3 from the post-change set time T2. Instruct the change target device.

Cases D2 to D4 are also substantially the same as cases B2 to B4 except that the time measurement start time of the change time elapsed time T3 is different from the time measurement start time in cases B2 to B4 described above. Omitted.
In cases D1 and D4, when any of the functions is executed or an operation is performed before the time obtained by subtracting the post-change elapsed time T3 from the post-change set time T2 after the affiliated group is changed. At that time, the elapsed time is reset to zero. Thereafter, the multifunction device 1 controls the transition operation to the power saving state based on the post-change setting time T2.

<Embodiment 3>
Next, Embodiment 3 will be described with reference to FIG.
With reference to FIG. 13, the operation 4 (transition to the power saving state) according to the third embodiment will be described. As in the second embodiment, the multifunction device 3 according to the third embodiment resets the elapsed time to zero at that time when any function is executed or an operation is performed during the normal state. To do.

  However, when the management apparatus 2 according to the third embodiment changes the group to which the multifunction machine 3 belongs, the management apparatus 2 changes to the change point elapsed time T3 and the pre-change set time T1 according to the second embodiment and continues in a normal state duration described below It is determined whether or not T4 is equal to or longer than the post-change set time T2.

  The normal state continuation time T4 refers to an elapsed time until the change target device finally returns to the normal state and changes to the power saving mode before changing the belonging group. As described above, when the multifunction device 3 executes a function while in the normal state or is operated, the elapsed time is reset to 0, and the elapsed time from the reset time reaches the pre-change set time T1. Therefore, the normal state continuation time T4 becomes longer than the pre-change set time T1. Therefore, the normal state continuation time T4 is equal to the accumulated time of the reset elapsed time, and is equal to or longer than the pre-change set time T1.

Therefore, when the pre-change set time T1 is equal to or longer than the post-change set time T2, the normal state duration T4 is also equal to or longer than the post-change set time T2.
Even if the pre-change set time T1 is less than the post-change set time T2, the normal state duration T4 may become equal to or greater than the post-change set time T2 by resetting the elapsed time.

  Cases E1 to E4 are substantially the same as Cases D1 to D4 described in the second embodiment except that the normal state duration T4 is used instead of the change point elapsed time T3 and the pre-change set time T1. Description is omitted.

<Other embodiments>
The present invention is not limited to the embodiments described with reference to the above description and the drawings, and for example, the following embodiments are also included in the technical scope.

  (1) In the above-described embodiment, for example, in the case of operations 1 to 3, if the change point elapsed time T3 is equal to or longer than the post-change set time T2, the change target device is configured to execute the operation immediately when the belonging group is changed. The case of instructing has been described as an example. However, the time point at which the operation is executed is not limited to this. The time at which the operation is executed may be any time as long as the post-change elapsed time T5 is before the post-change set time T2. The same applies to operations 4 and 5.

  (2) In the above embodiment, for example, in the case of operations 1 to 3, when the change time elapsed time T3 is less than the changed set time T2, the changed time elapsed T5 is changed from the changed set time T2 to the change time elapsed time T3. An example has been described in which the change target apparatus is instructed to execute an operation when the time when the time is reduced is reached. However, the time point at which the operation is executed is not limited to this. The time at which the operation is executed is an arbitrary time as long as the post-change elapsed time T5 reaches the time obtained by subtracting the change time elapsed time T3 from the post-change set time T2 and before the post-change set time T2. It's okay. The same applies to operations 4 and 5.

(3) In the above embodiment, the case where the count value is the elapsed time and the set value is the set time has been described as an example. However, the count value and the set value are not limited to these.
For example, consider a case where the color misregistration correction process is executed every time the number of printed sheets reaches a set number. In this case, the count value may be the number of printed sheets, and the set value may be the set number of sheets. In this case, when the number of printed sheets at the time of the change is referred to as the number of printed sheets at the time of change T3 and the set number of sheets set in the group to which the change has been made is referred to as the set number of changed sheets T2, it is determined whether or not Expression 1 is satisfied. Execute the first determination process;
Number of printed sheets T3 at the time of change ≧ Number of set sheets T2 after the change Expression 1

If an affirmative determination is made in the first determination process, the change target device is caused to execute a color misregistration correction process when the group to which the change target device belongs is changed. If a negative determination is made, the belonging group is changed. When the number of printed sheets whose starting point is the count is referred to as a post-change number of printed sheets T5, when the post-change number of printed sheets T5 satisfies Equation 2, the change target apparatus may be caused to execute color misregistration correction processing.
Number of printed sheets after change T5 ≧ Number of set sheets after change T2−Number of printed sheets at time of change T3 Expression 2

(4) In the above embodiment, the elapsed time is reset to 0 at the time when the group is changed, and the post-change elapsed time T5 is counted, and the post-change elapsed time T5 is changed from the post-change set time T2 to the change time elapsed time T3. An example has been described in which the change target apparatus is instructed to execute an operation before reaching the post-change set time T2 after the time when the time is reduced.
However, the elapsed time counted from before the change of the belonging group may be continuously used without resetting the elapsed time when the belonging group is changed.
For example, in case A1, the elapsed time counted from before the group is changed is continuously counted even when the group is changed, and the elapsed time reaches the set time after the change (P2 in FIG. 4). ), The operation may be executed before reaching the time (P3 in FIG. 4) obtained by adding the set time after change to the elapsed time at the time when the group is changed. Then, the elapsed time may be reset to 0 at the timing start time determined according to the operation.

  (5) In the above embodiment, operations 1 to 5 have been described as operations. However, other operations may be performed as long as the operations are executed when the count value reaches the set value.

  (6) In the above embodiment, a personal computer has been described as an example of a management apparatus. On the other hand, any one of the plurality of multifunction devices 3 may also serve as a management device.

  (7) In the above embodiment, the deletion of the secure print job has been described as the operation 5 as an example. On the other hand, the technique disclosed in this specification can also be applied to so-called storage printing. In storage printing, a print job is stored in a storage device of a multifunction peripheral, and printing is performed when a user instructs printing of the print job. Unlike secure print jobs, authentication information such as a password is not required for storage printing.

  (8) In the above embodiment, the case where S501 is executed in the process in the case of T3 <T2 has been described as an example. On the other hand, S501 may not be executed.
