Image forming apparatus capable of counting consumable consumption amount, and control method and control program therefor
First Claim
1. An image forming apparatus comprising:
- an image forming device that performs an image forming process using a consumable material;
a transfer device that transfers image data to said image forming device; and
a disable device operable when the image forming process by said image forming device is interrupted during execution of a count process for counting an amount of the consumable material to be consumed based on the image data transferred by said transfer device, to disable the count process without stopping a transfer process of the image data by said transfer device.

Abstract
An image forming apparatus which is capable of accurately performing a video count process based on image data and thus maintaining the quality of images even where DMA transfer processing is used. An image forming device performs a process using a consumable material. A first controller controls the image forming device. A transfer controller provides control to transfer externally input image data to the first controller. A second controller performs a count process for counting an amount of the consumable material to be consumed based on the image data transferred by the transfer controller. The second controller disables the count process without stopping the transfer by the transfer controller when the process performed by the image forming device is interrupted.

2. A control method for an image forming apparatus comprising an image forming device that performs a process using a consumable material, and a controller that controls the image forming device, the control method comprising:
-
a transfer control step of transferring image data to the controller; and a control step of performing a count process for counting an amount of the consumable material to be consumed based on the image data transferred in said transfer control step, wherein in said control step, the count process is disabled without stopping a transfer process for transferring data to the controller when the process performed by the image forming device is interrupted. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12)

13. A control method for an image forming apparatus including an image forming device that performs an image forming process using a consumable material, the control method comprising:
-
a transfer step of transferring image data to the image forming device; and a disable step of disabling, when the image forming process by the image forming device is interrupted during execution of a count process for counting an amount of the consumable material to be consumed based on the image data transferred in said transfer step, the count process without stopping a transfer process to the image forming device.

14. A data storage device storing a computer control program executed by a second controller of an image forming system having the second controller, an image forming device that performs a process using a consumable material, and a first controller that controls the image forming device, wherein the second controller transfers image data to the first controller and performs a count process for counting an amount of the consumable material to be consumed based on the image data, the computer control program comprising:
a module for disabling the count process without stopping a transfer process for transferring data to the first controller when the process performed by the image forming device is interrupted.
-
15. A data storage device storing a computer control program executed by a supply controller of an image forming apparatus, wherein the image forming apparatus has an image forming device that performs an image forming process on image data using a consumable material, and the supply controller that supplies image data on which the image forming process is to be performed by the image forming device, the computer control program comprising:
-
a transfer module for transferring image data to the image forming device; and a disable module for disabling, when the image forming process by the image forming device is interrupted during execution of a count process for counting an amount of the consumable material to be consumed based on the image data transferred by said transfer module, the count process without stopping a transfer process to the image forming device.
