Abstract:
An image forming apparatus for forming an image on a photoconductor by scanning light on the photoconductor, the apparatus comprising;a printer engine configured to form the image, the printer engine including a polygon motor configured to revolve at an arbitrary rate of revolution, a deflector driven by the polygon motor and configured to rotate to deflect the light, and a motor control configured to control the revolution of the polygon motor; and a controller configured to control the apparatus, configured to cause the polygon motor to stop revolving when the apparatus is in a waiting status, and configured to output to the printer engine, when the apparatus is set to form the image with a single picture element resolution, (1) a revolution request to revolve the polygon motor immediately after receiving a printing instruction to form the image from a host computer coupled to the apparatus and (2) a printing request to form the image after completing image processing for forming the image, said printing request being different from the printing instruction; wherein the printer engine is configured to stop the revolution of the polygon motor when the printer engine does not receive the printing request from the controller within a predetermined time after receiving the revolution request from the controller.
