ABSTRACT:
An image formation apparatus includes an automatic adjustment unit for automatic adjustment of the apparatus, a job queuing unit for queuing image formation jobs, a counting unit for counting the number of pages from the previous automatic adjustment for each automatic adjustment unit, and a determining unit for determining whether the number of image formation pages for automatic adjustment will be reached during the execution of the image formation queued job. In the event that the determining unit determines that the number of image formation pages for automatic adjustment will be reached during execution of the image formation job queued by the job queuing unit, automatic adjustment is performed before starting execution of the image formation queued job, even though the number of image formation pages counted by the counting unit has not reached the number for the automatic adjustment.
