Abstract
Provided is an image forming apparatus for performing an image adjustment in a monochrome image formation mode. In a case where color information for subsequent images includes a color image, the image forming apparatus does not perform an image adjustment in the monochrome image formation mode. Rather, image forming apparatus performs the image adjustment in a color image formation mode in a case where a subsequent color image is formed.
Claims7
An image forming apparatus configured to operate a color image formation mode and a monochrome image formation mode, the image forming apparatus comprising:
- a controller configured to:
- perform a first count of sheets on which an image is formed in the color image formation mode;
- perform a second count of sheets on which an image is formed in the monochrome image formation mode;
- acquire an image forming job;
- in a case where the first count exceeds a first threshold in the color image formation mode, perform an image adjustment in the color image formation mode;
- in a case where the second count exceeds a second threshold and at least one subsequent image in the acquired image forming job does not include an image to be formed in the color image formation mode, perform an image adjustment in the monochrome image formation mode;
- and
- in a case where at least one subsequent image in the acquired image forming job includes an image to be formed in the color image formation mode, the second count exceeds the second threshold and the first count exceeds the first threshold at a timing when the at least one subsequent image is formed in the color image formation mode, perform an image adjustment in the color image formation mode without performing an image adjustment in the monochrome image formation mode.
A method of controlling an image forming apparatus configured to operate a color image formation mode and a monochrome image formation mode, the method comprising:
- performing a first count of sheets on which an image is formed in the color image formation mode;
- performing a second count of sheets on which an image is formed in the monochrome image formation mode;
- acquiring an image forming job;
- in a case where the first count exceeds a first threshold in the color image formation mode, performing an image adjustment in the color image formation mode;
- in a case where the second count exceeds a second threshold and at least one subsequent image in the acquired image forming job does not include an image to be formed in the color image formation mode, performing an image adjustment in the monochrome image formation mode;
- and
- in a case where at least one subsequent image in the acquired image forming job includes an image to be formed in the color image formation mode, the second count exceeds the second threshold and the first count exceeds the first threshold at a timing when the at least one subsequent image is formed in the color image formation mode, performing an image adjustment in the color image formation mode without performing an image adjustment in the monochrome image formation mode.
A non-transitory computer readable storage medium including a program causing an image forming apparatus configured to operate a color image formation mode and a monochrome image formation mode to:
- performing a first count of sheets on which an image is formed in the color image formation mode;
- performing a second count of sheets on which an image is formed in the monochrome image formation mode;
- acquiring an image forming job;
- in a case where the first count exceeds a first threshold in the color image formation mode, performing an image adjustment in the color image formation mode;
- in a case where the second count exceeds a second threshold and at least one subsequent image in the acquired image forming job does not include an image to be formed in the color image formation mode, performing an image adjustment in the monochrome image formation mode;
- and
- in a case where at least one subsequent image in the acquired image forming job includes an image to be formed in the color image formation mode, the second count exceeds the second threshold and the first count exceeds the first threshold at a timing when the at least one subsequent image is formed in the color image formation mode, performing an image adjustment in the color image formation mode without performing an image adjustment in the monochrome image formation mode.
