  Further, the detection results Rd of the printing material remaining amount detection unit 42a, the paper remaining amount detection unit 43a, the staple remaining amount detection unit 44a, and the punch waste storage remaining amount detection unit 45a acquired by the print allowable amount monitoring unit 54 are, for example, As shown in FIG. FIG. 5 is a conceptual diagram illustrating an example of a monitoring result by the print allowable amount monitoring unit 54 in the image forming apparatus 1. The remaining amounts of the printing resources “paper (A4)” and “paper (A3)” in this example correspond to the detection results of the remaining paper amount detection unit 43a, and the remaining amount of the printing resource “toner (K)” is This corresponds to the detection result of the remaining printing material detection unit 42a. Further, the remaining amount of the printing resource “staple” corresponds to the detection result of the remaining staple amount detecting unit 44a, and the printing resource “punching waste” corresponds to the detection result of the remaining punch waste remaining amount detecting unit 45a. Although punch scraps are not printing resources, in the example shown in FIG. 5, they are called printing resources for convenience.

  The replenishment necessity determination unit 52 obtains the quantity of each of the printing material, printing paper, and staples necessary for executing the reserved print job, and the remaining amount of punch waste necessary for executing the reserved print job, for example, FIG. As shown in FIG. 6, these quantities are compared with the detection result Rd, and it is determined whether it is necessary to replenish print resources or discard punch scraps during the execution of the reserved print job. FIG. 6 is a conceptual diagram illustrating an example of data comparison when the replenishment necessity determination unit 52 of the image forming apparatus 1 determines whether or not a print resource needs to be replenished. In this example, 100 sheets of “paper (A4)” are insufficient during execution of the reserved print job, so the replenishment necessity determination unit 52 needs to supply 100 sheets of “paper (A4)”. Judge.

  The determination result D of the replenishment necessity determination unit 52 in the above-described replenishment necessity determination step S4 is sent to the determination result notification unit 6 as shown in FIG. The determination result notifying unit 6 that has received the determination result D performs notification processing step S5 for creating predetermined notification data Ad corresponding to the determination result D, and sends the notification data Ad to the input / output unit 2.

  The input / output unit 2 that has received the notification data Ad transmits the notification data Ad from the communication unit 22 to a predetermined user, that is, a user specified by the address information in the reserved print job data. For example, a notification screen AS shown in FIG. 7 is displayed on the node of the user who has received the notification data. The notification screen AS displays a message M1 that notifies the replenishment necessity determining unit 52 that replenishment is necessary, a message M1 that notifies the replenishment amount, and a message M2 that prompts replenishment of the print resource. FIG. 7 is a schematic diagram illustrating an example of a notification screen indicating the determination result of the replenishment necessity determination unit 52 in the image forming apparatus 1. Of course, when the replenishment necessity determination unit 52 determines that staple replenishment is necessary, a message for notifying the staple replenishment amount and a message for prompting staple replenishment are displayed on the notification screen AS. In addition, when the replenishment necessity determination unit 52 determines that it is necessary to discard punch scraps, a message for notifying punch scraps is displayed on the notification screen AS.

  In the sequence shown in FIG. 2, the reservation print job received by the communication unit 22 (see FIG. 1) is received by the input / output unit 2 and sent to the job registration processing unit 51. The part 41 (refer FIG. 1) may acquire. In this case, the contents of the reserved print job (excluding image data) are input from the input unit 21 and received by the input / output unit 2, for example. The reserved print job is stored in the job data storage unit 32 by the job control unit 47 (see FIG. 1), and the reserved print job is stored in the job data storage unit 32 by, for example, the job registration processing unit 51. The notification screen indicating the determination result of the replenishment necessity determination unit 52 is displayed on the display unit 23 (see FIG. 1), for example.

  As shown in FIG. 8, when “print resource confirmation time” information corresponding to the determination time designation information for designating the determination time for necessity of replenishment of print resources is included in the reserved print job data, for example, FIG. In the sequence shown in FIG. 9, the image forming apparatus 1 performs operations from setting a reserved print job to notifying / displaying the result of determining whether or not to replenish printing resources and discard punch scraps. FIG. 8 is a conceptual diagram illustrating another example of reserved print job data stored in the job data storage unit 32 of the image forming apparatus 1. FIG. 9 is a sequence diagram illustrating an example of the operation of the image forming apparatus 1 when the reserved print job data includes information Ta that designates a determination time for determining whether or not to supplement a print resource.

  As is clear from the comparison between FIG. 8 and FIG. 3, in the reserved print job data PJ2 shown in FIG. 8, the value “17:00” is set in the “print resource confirmation time” corresponding to the determination time designation information Ta. The contents are the same as those of the reserved print job data PJ shown in FIG. Since the determination print designation data Ta is included in the contents of the reserved print job data PJ2, the necessity determination request unit 53 that monitors the contents of the reserved print job data PJ2 determines the time (determination) corresponding to the determination print designation data Ta. The time confirmation step S11 for determining whether or not the time has come is repeated. When it is determined that the determination time has come, the necessity determination request unit 53 sends a replenishment necessity confirmation request Ra to the replenishment necessity determination unit 52.

  Therefore, even if the replenishment necessity confirmation step S3 shown in FIG. 2 is omitted, whether or not replenishment of printing resources or disposal of punch waste is necessary during execution of the reserved print job is determined. And a notification screen indicating the determination result is displayed on the user's node. Of course, the replenishment necessity confirmation step S3 shown in FIG. 2 can be performed at a desired time.

  The determination time designation information Ta may be already included in the contents of the reserved print job Pa when the job registration processing unit 51 stores the reserved print job Pa in the job data storage unit 32, or may be added thereafter. Good. For example, when the input unit 21 receives an input permission request for permission to input the determination time designation information Ta, an input screen for inputting the determination time designation information Ta is displayed on the user node or the display unit 23. Alternatively, the image forming apparatus 1 may be configured. In this case, the input / output unit 2 that has received the input permission request sends a predetermined signal to the job registration processing unit 51, and the job registration processing unit 51 that has received the signal receives all the reservations from the job data storage unit 32. The print job data is read out, and information relating to the setting status of the job identification information and determination time designation information Ta of each reserved print job is sent to the input / output unit 2 as screen display information. The input / output unit 2 that has received the screen display information transmits the screen display information to the user's node or causes the display unit 23 to display the input screen using the screen display information.

  FIG. 10 is a schematic diagram illustrating an example of an input screen for inputting the determination time designation information Ta to the image forming apparatus 1. In the input screen ES2 shown in FIG. 10, based on the reserved print job data stored in the job data storage unit 32, “reserved print job name” corresponding to job identification information and “confirmation time” corresponding to determination time designation information. "Is displayed for each reserved print job, and a guide message GM2 indicating how to operate is displayed. The “confirmation time” column of the reserved print job for which the determination time is not specified is blank. When a desired reserved print job name is designated and its “confirmation time” is input, information on the designated reserved print job name and determination time designation information Ta corresponding to the inputted “confirmation time” are input / output unit 2. Is sent to the job registration processing unit 51. The job registration processing unit 51 that has received the information adds the determination time designation information Ta to the reserved print job data corresponding to the reserved print job name designated by the user. From the input screen ES2, it is also possible to input one determination time designation information Ta for all the reserved print jobs at once.

  In addition, when user identification information, user schedule information, and replenishment person identification information are stored in the schedule information storage unit 34 (see FIG. 1), the job registration that has received a predetermined instruction signal from the input / output unit 2 The image forming apparatus 1 may be configured such that the processing unit 51 reads out such information, selects a predetermined time, and adds determination time designation information Ta corresponding to this time to the reserved print job data. In this case, based on the user schedule information of the user specified by the replenishment person identification information, the job registration processing unit 51 determines a predetermined final time at which the user can replenish print resources or discard punch scraps. The time before the time is selected as the determination time for necessity confirmation. The time before the last time is set as the determination time by the control program of the job registration processing unit 51 in advance.

  FIG. 11 is a conceptual diagram showing an example of the user schedule information used in the image forming apparatus 1. As shown in FIG. 11, the user schedule information includes “date” that is date information, “user” that is user identification information, and “company time” that is information on the scheduled office time for each user. In addition, each item of “leaving time”, which is information of the scheduled leaving time for each user, can be included, and the input information for each item of “leaving time” and “leaving time” is information indicating that the user does not go to work. A “rest” can be included.

  FIG. 12 is a conceptual diagram illustrating an example of replenishment person identification information used in the image forming apparatus 1. As shown in FIG. 12, the replenishment person identification information includes “name” that is user identification information, and replenishment of print resources on behalf of the user who reserved the reserved print job on the above-mentioned “rest”. In addition, each item of “agent”, which is user identification information of other users who are responsible for disposal of punch scraps, can be included.

  In the image forming apparatus 1, a plurality of reserved print jobs are stored in the job data storage unit 32, and a reserved print job whose execution order is earlier than the reserved print job to which the necessity confirmation request Ra is sent. In some cases, the total print resource consumption and the total amount of punch scrap generated in the reserved print job to which the necessity confirmation request Ra is sent and all the reserved print jobs whose execution order is earlier than the reserved print job are taken into account. The replenishment necessity determination unit 52 can also determine whether or not it is necessary to replenish printing resources or discard punch scraps.

  FIG. 13 shows whether or not it is necessary to replenish print resources or discard punch scraps during execution of one reserved print job in the image forming apparatus 1, according to the execution order of the reserved print job and the reserved print job. It is a flowchart which shows an example of the judgment procedure when the replenishment necessity confirmation part 52 judges considering the total consumption of the printing resource in all the previous reserved print jobs, and the total generation amount of punch waste. In this example, the replenishment necessity determination unit 52 performs steps S21 to S25.

  Step S21 is started when the necessity confirmation request Ra for one reserved print job is sent. In this step S 21, the replenishment necessity confirmation unit 52 acquires information on the execution start time of the reserved print job, which is a determination target of whether or not it is necessary to replenish printing resources or discard punch scraps, from the job data storage unit 32.

  In step S22, the replenishment necessity confirmation unit 52 accesses the job data storage unit 32, and the reserved print job having the execution start time set before the time corresponding to the information of the execution start time acquired in step S21. Search for.

  In step S23, the replenishment necessity determination unit 52 determines whether there is a corresponding reserved print job as a result of the search in step S22. When it is determined that there is no corresponding reserved print job, the process proceeds to step S24, and when it is determined that there is a corresponding reserved print job, the process proceeds to step S25.

  In step S24, the necessity of replenishment of the print resource, the replenishment amount of the print resource, based on the print resource amount necessary for execution of the reserved print job to which the necessity confirmation request Ra is sent and the remaining amount of punch waste, And the replenishment necessity judgment part 52 judges the necessity of discard of punch waste.

  In step S25, the total print resource consumption and the total amount of punch waste generated in the reserved print job to which the necessity confirmation request Ra is sent, all the reserved print jobs whose execution order is earlier than the print job are determined. The replenishment necessity determination unit 52 calculates and determines the total print resource amount and the total remaining amount of punch waste required to execute these reserved print jobs. Then, based on these calculation results, the current print resource amount, and the remaining amount of punch waste, replenishment of print resources and disposal of punch waste during execution of the reserved print job to which the necessity confirmation request Ra is sent. The replenishment necessity determination unit 52 determines whether or not it is necessary.

  In the image forming apparatus 1, a plurality of reserved print jobs are stored in the job data storage unit 32, and the execution order is higher than that of the reserved print job determined by the replenishment necessity confirmation unit 52 that the replenishment necessity confirmation unit 52 determines that the replenishment of print resources is necessary. When there is a later reserved print job, the replenishment necessity confirmation unit 52 may automatically determine that it is necessary to replenish print resources even for a reserved print job whose execution order is later. When configured in this way, the input / output unit 2 is directed to the setting user of each reserved print job determined by the replenishment necessity determination unit 52 that the replenishment of print resources is necessary. The determination result is output from the communication unit 22.

  Since the image forming apparatus 1 configured as described above does not reserve the print resources necessary for executing the reserved print job in advance, the non-reserved print job is executed even when the reserved print job is set. When there are sufficient print resources in the job execution unit 4 and the remaining amount of punch waste is sufficient, the non-reserved print job can be executed without replenishing the print resources and discarding the punch waste.

  In the image forming apparatus 1, the replenishment necessity determination unit 52 determines whether or not it is necessary to replenish printing resources or discard punch scraps during execution of the reserved print job, and this determination result is the input / output unit 2. Therefore, when it is necessary to replenish printing resources and discard punch scraps when executing a reserved print job, it is possible to prompt the user to replenish or discard the reserved print job before the execution start time of the reserved print job. Therefore, according to the image forming apparatus 1, both the reserved print job and the non-reserved print job can be smoothly performed.

  The image forming apparatus and the program thereof according to the present invention have been described with reference to the embodiment. However, as described above, the present invention is not limited to the above embodiment. For example, the image forming apparatus of the present invention is not limited to one that can be shared by a plurality of users, and may be dedicated to one user.

It may be. Whether or not to add a network connection function to the image forming apparatus of the present invention can be appropriately selected. Also, whether or not to add a document storage function to the image forming apparatus of the present invention can be selected as appropriate.

  Furthermore, whether or not a stapling part or a punching part is provided in the image forming apparatus of the present invention can be selected as appropriate. The printing unit may have at least one inkjet nozzle and an ink supply unit that supplies ink to the nozzle instead of the photosensitive drum and the toner. In this case, the printing material remaining amount detection unit The remaining amount of ink is detected based on the change in mass of the supply unit, the number of printed sheets in the printing unit, and the like.

  The replenishment necessity determination unit only needs to be able to determine whether or not replenishment of printing resources is necessary during execution of a reserved print job, and has a replenishment function for determining whether or not punch scraps need to be discarded. Whether or not to add to the refusal determination unit can be selected as appropriate. When a reserved print job is set via the communication unit of the input / output unit, the determination result of the replenishment necessity determining unit is displayed on both the user node that has set the reserved print job and the display unit of the input / output unit. It may be displayed. Whether or not to make the replenishment necessity determination unit determine the replenishment amount of the printing resource can be selected as appropriate.

  Also, whether or not to include staples in the print resource can be selected as appropriate. Therefore, the allowable printing amount monitoring unit may be any unit that monitors at least the detection results of the remaining printing material detection unit and the remaining sheet detection unit.

  The necessity determination request unit can be an arbitrary component. However, in order to make the replenishment necessity determination unit surely determine whether or not the replenishment of printing resources is required at a desired time, it is preferable to provide a necessity determination request unit. The schedule registration processing unit can also be an arbitrary component, and accordingly, the schedule information storage unit can also be an arbitrary component.

  Even when the schedule registration processing unit and the schedule information storage unit are constituent elements, user identification information and user schedule information stored in the schedule information storage unit only when a predetermined operation mode is set from the input / output unit In addition, the image forming apparatus can be configured such that the job registration processing unit adds the determination time designation information to the reserved print job data based on the replenishment person identification information. The image forming apparatus and the program of the present invention can be variously modified, decorated, combined and the like in addition to the above.
