Abstract
A processor places a printer apparatus in a reduced activity mode after printing requests have not been received for an “inactivity” time period. A belt support device rotates a photoreceptor belt at a reduced speed when the printer apparatus enters the reduced activity mode and for a “delay” time period after the printer apparatus enters the reduced activity mode. The belt support device returns the rotational speed of the photoreceptor belt to the original speed if a new printing request is received during the delay time period. However, the belt support device stops rotation of the photoreceptor belt and reduces the belt tension if the delay time period expires without receiving a new printing request.
