Abstract
Heatset of a fusing roller in a fuser in which the rollers are not separated during standby is prevented by periodically rotating the rollers. To prevent a temperature surge caused by elimination of heat-absorbing sheets between the rollers during standby, the rollers are rotated at a reduced speed for a short time at the beginning of the standby period after a run. To also prevent temperature fluctuations due to the periodic rotation during standby, that rotation is controlled to a small amount to prevent the sensor from contacting an entirely new portion of the fusing roller surface with each periodic rotation.
