Next, the operation in the first embodiment will be described.
FIG. 7 shows a maintenance member registration / cancellation process executed by the image forming apparatus 1. This processing is realized by software processing in cooperation with the CPU 24 and the maintenance member registration program stored in the program memory 25, and is processing executed before image formation.

  First, a list of members included in the image forming apparatus 1 and whether or not each member is registered as being maintainable are displayed on the operation display unit 17 (step S1). Each user selects a member that can be maintained, inputs a selection instruction or a change instruction, and registers the member as a member that can be maintained. Specifically, as shown in FIG. 3, the LCD 172 displays a list of members included in the image forming apparatus 1 and whether or not each member is registered as maintainable as an input screen, and the user can perform maintenance. And press the button of the member to be registered, put a check mark, and press the registration button. On the other hand, when canceling the registration, the user depresses the button of the member to be canceled to remove the check mark, and presses the registration button. Information on the member having a check mark when the registration button is pressed is output to the CPU 24 as maintenance member registration information, and information indicating that the member is registered / released is written in the nonvolatile memory 27 (step S3). ,finish.

Once the maintenance / registration processing of the member that can be maintained is completed, the image formation is possible.
When the image can be formed, the user selects one of the paper trays 4a to 4e that stores a desired sheet from the large capacity tray unit 3, and sets the sheet, and then causes the image forming unit to form an image. .
Specifically, based on the control from the printer control unit 331, the printing unit 332 feeds the paper used in the job from one of the selected paper trays 4a to 4e by the transport unit and is fed. Transport the paper on the transport path. In the image forming unit, the surface of the photosensitive drum 13 is charged by the charger 12 based on an instruction from the printer control unit 331, and the photosensitive drum is driven by the LD 11 based on the PWM signal input from the writing processing unit 31. An electrostatic latent image is formed by irradiating the surface 13 with laser light, and toner is attached to a region including the electrostatic latent image on the surface of the photosensitive drum 13 by the developing device 14. Then, toner is transferred to the conveyed paper by the transfer unit 15 to form an image and fixed by the fixing unit 16. The sheet on which the image has been formed is conveyed to the discharge tray 7 by the discharge roller 8.

When performing image formation in this way, the image forming apparatus 1 adds up the count value of each member for each operation, determines whether the count value exceeds the limit value, and the count value exceeds the limit value. Displays a warning message prompting maintenance.
Here, processing when the count values of the respective members are integrated and exceed the limit value will be described with reference to FIG.

  First, the program memory 25 counts up the count value according to the integration condition for each member during image formation (step S4). After the count-up, the program memory 25 compares the counter value with the limit value for each member according to the determination program. If the count value is lower than the limit value (step S5; No), the image formation is continued. On the other hand, if the count value is equal to or greater than the limit value (step S5; Yes), it is determined that the member requires maintenance, and it is determined whether or not the member is registered as capable of maintenance (step S6). When the member is registered in the maintenance member registration program (step S6; Yes), a warning message indicating that maintenance is required is displayed to the user (step S7). Then, the user presses an operation button or the like to display a confirmation screen (see FIG. 5) on the LCD 172, confirms a member whose count value exceeds the limit value, and performs maintenance of the member. Further, even if a member is determined to require maintenance, if it is determined that image formation will not be adversely affected without immediate maintenance, the original display on the LCD 172 is displayed on the original screen (see FIG. 4). ) And the image forming process may be continued.

  On the other hand, if the member is not registered as being maintainable (step S6; No), it is a member that cannot be maintained by the user, and a warning message is displayed on the LCD 172 so as to call the service person to the user (step S6). S8).

  When the maintenance is completed, as shown in FIG. 9, the user resets the displayed count value and deletes the warning message. Specifically, when the member button (step S9) and the count reset button (step S10) for resetting the count value are sequentially pressed on the display screen (see FIG. 3) on which the member list included in the image forming apparatus 1 is displayed, the CPU 24 is pressed. Displays a reset confirmation screen on the LCD 172 (see FIG. 6). Then, when the user presses the acceptance button (“Yes” in FIG. 6), the CPU 24 determines whether or not the member is registered as being maintenanceable (step S11). In the case of a member registered as capable of maintenance (step S11; Yes), counter reset instruction information by the user is output to the CPU 24, the counter of the member is reset by the reset program, and the count value becomes zero (step S12). ) And the warning message are erased (step S13), and the process ends. Here, in this embodiment, after displaying all the member lists and allowing the user to select, it is determined whether or not the member is registered as maintainable, but the member registered as maintainable. It is also possible to display a list of only and reset the count.

  As described above, according to the image forming apparatus 1, since the user can select and set a member that can be maintained and change the registered content, maintenance according to the technical level of the user can be performed. . Therefore, the user can also perform maintenance and the like that has conventionally been performed by a serviceman, and the downtime required for recovery can be reduced. In addition, since members that can be maintained are registered according to the technical level of the user, it is possible to prevent work mistakes without forcing unfamiliar maintenance to the user.

  In addition, since the degree of deterioration is integrated to determine whether maintenance is necessary, it is possible to easily know the maintenance time of the member. Since the user performs maintenance by selecting an arbitrary member from among the members displayed that the degree of deterioration exceeds the threshold, maintenance can be performed in accordance with the user's technical level. . Further, when the degree of deterioration exceeds a threshold value, the user does not need to perform maintenance immediately, and maintenance can be performed according to the stock of each member.

  Furthermore, the counter of each member registered as being maintainable can be reset, and the user can accurately know the degree of deterioration of each member by resetting the counter after performing maintenance.
