摘要:
An image formation device, such as a printer, forms an image in a transfer format. The image formation device is configured to execute a predetermined down sequence to prepare the device for the next image formation operation after completion of an image formation operation. Alternatively, when a predetermined condition is satisfied, the device is configured to execute a blank rotation sequence instead of executing the down sequence after completion of an image formation operation. The device may have the ability to form an image from different image generation sources. A determination of whether an image formation operation switches from one image generation source to using another image generation source may be based on whether the predetermined condition is satisfied. The predetermined condition may be that the sizes of the images formed using each image generation source are equal. The down sequence may include a density control for stabilizing a cleaning operation inside the device and an output density of the device. The blank rotation sequence may not include the density control. The device may also be configured to restart an image formation operation after the blank rotation sequence.
