Abstract
An image forming apparatus is capable of minimizing the deterioration of image quality by suspending a calibrating process in a predetermined case while improving user convenience. While in the suspended state, when a predetermined condition is satisfied, the multifunction machine can force the calibrating process in the print job, and when the predetermined condition is not satisfied, the calibrating process is not forced in the print job.
Claims5
An image-forming apparatus comprising:
- means for printing a print job;
- means for suspending a calibrating process during printing of the print job if at least one of the following suspension conditions (A) and (B) is satisfied:
- (A) an instruction to suspend the calibrating process is done by a user, the calibrating process being to amend image density of the print job;
- (B) the print job is for a copy function;
- means for executing the calibrating process when either of the two suspension conditions is not satisfied and an operating amount of the printing means reaches a normal threshold;
- and
- means for forcing the calibrating process in the print job, wherein, while one of the suspension conditions is satisfied and the calibrating process is suspended,
- when the operating amount of the printing means reaches a suspension threshold larger than the normal threshold, the calibrating process is forced in the print job, and
- when the operating amount of the printing means does not reach a suspension threshold, the calibrating process is not forced in the print job.
