Abstract

According to one embodiment, an image forming apparatus includes a plurality of parts, an acquisition unit, and a control unit. The plurality of parts are used in the image forming process and are replaced according to the degree of use. The acquisition unit acquires, for each of the parts, use-related information that is information indicating the degree of use of the plurality of parts. The control unit determines the replacement timing of the part using the plurality of pieces of use-related information acquired by the acquisition unit and the determination condition regarding the replacement timing of the part.

Claims (50)

1. An image forming apparatus, comprising:

a plurality of consumable items used for an image forming process and replaced according to a degree of use; and

a processor that performs, for each consumable item of the plurality of consumable items, one or more operations stored in a computer-readable memory, such one or more operations comprising:

acquiring a plurality of use-related information indicating the degree of use of the consumable item;

determining a replacement timing of the consumable item based on the plurality of use-related information and a determination condition regarding the replacement timing of the consumable item; and

evaluating whether or not the determination condition is satisfied by any of the plurality of use-related information;

wherein, if the processor concludes that the determination condition is satisfied by any of the plurality of use-related information, the processor performs a determination process, which includes determining whether or not the replacement timing of the consumable item is reached via a learned model, wherein the learned model is acquired by performing a learning process in advance based on the plurality of use-related information and information indicating whether or not the consumable item needs to be replaced when the plurality of use-related information is acquired; and

wherein, if the processor concludes that the determination condition is not satisfied by any of the plurality of use-related information, the processor refrains from performing the determination process.

2. The apparatus according to claim 1 , further comprising:

a display, wherein

the processor displays on the display a replacement alert urging replacement of the consumable item, when the replacement timing is reached.

3. The apparatus according to claim 1 , wherein

the processor initializes the use-related information when the consumable item is replaced.

4. The apparatus according to claim 1 , wherein

the processor updates the replacement timing when the replacement timing is not reached.

5. The apparatus according to claim 1 , wherein

the replacement timing comprises a number-of-sheets replacement timing or a number-of-rotations replacement timing.

6. The apparatus according to claim 1 , wherein

the use-related information comprises a cumulative number of rotations of a motor, a cumulative drive time of the motor, or a cumulative traveling distance of the motor.

7. A control method of an image forming apparatus that includes a plurality of consumable items used for an image forming process and replaced according to a degree of use, the method comprising:

acquiring, by a processor and for each consumable item of the plurality of consumable items, a plurality of use-related information indicating the degree of use of the consumable item;

determining, by the processor, a replacement timing of the consumable item, based on the plurality of use-related information and a determination condition regarding the replacement timing of the consumable item; and

evaluating, by the processor, whether or not the determination condition is satisfied by any of the plurality of use-related information;

wherein, if the processor concludes that the determination condition is satisfied by any of the plurality of use-related information, the processor performs a determination process, which includes determining whether or not the replacement timing of the consumable item is reached via a learned model, wherein the learned model is acquired by performing a learning process in advance based on the plurality of use-related information and information indicating whether or not the consumable item needs to be replaced when the plurality of use-related information is acquired; and

wherein, if the processor concludes that the determination condition is not satisfied by any of the plurality of use-related information, the processor refrains from performing the determination process.

8. The method according to claim 7 , further comprising:

displaying, by the processor, a replacement alert urging the replacement of the consumable item on a display when the replacement timing is reached.

9. The method according to claim 7 , further comprising:

initializing, by the processor, the use-related information when the consumable item is replaced.

10. The method according to claim 7 , further comprising:

updating, by the processor, the replacement timing when the replacement timing is not reached.

11. The method according to claim 7 , wherein

the replacement timing comprises a number-of-sheets replacement timing or a number-of-rotations replacement timing.

12. The method according to claim 7 , wherein

the use-related information comprises a cumulative number of rotations of a motor, a cumulative drive time of the motor, or a cumulative traveling distance of the motor.

13. A replacement notification system, comprising:

a processor that performs one or more operations stored in a computer-readable memory, such one or more operations comprising:

acquiring, for each consumable item of a plurality of consumable items used for an image forming process and replaced according to a degree of use, a plurality of use-related information indicating the degree of use of the consumable item;

determining a replacement timing of the consumable item based on the plurality of use-related information and a determination condition regarding the replacement timing of the consumable item; and

evaluating whether or not the determination condition is satisfied by any of the plurality of use-related information;

wherein, if the processor concludes that the determination condition is satisfied by any of the plurality of use-related information, the processor performs a determination process and a display process, wherein the determination process includes determining whether or not the replacement timing of the consumable item is reached via a learned model, wherein the learned model is acquired by performing a learning process in advance based on the plurality of use-related information and information indicating whether or not the consumable item needs to be replaced when the plurality of use-related information is acquired, and wherein the display process includes displaying on a display a replacement alert urging the replacement of the consumable item when the replacement timing is reached; and

wherein, if the processor concludes that the determination condition is not satisfied by any of the plurality of use-related information, the processor refrains from performing the determination process and the display process.

14. The apparatus according to claim 13 , wherein

the processor initializes the use-related information when the consumable item is replaced.

15. The apparatus according to claim 13 , wherein

the processor updates the replacement timing when the replacement timing is not reached.

16. The apparatus according to claim 13 , wherein

the replacement timing comprises a number-of-sheets replacement timing or a number-of-rotations replacement timing.

17. The apparatus according to claim 13 , wherein

the use-related information comprises a cumulative number of rotations of a motor, a cumulative drive time of the motor, or a cumulative traveling distance of the motor.
