Summary:A fuser assembly includes a heated member and a backup member defining a fusing nip. Toner fuses to media in the nip at a fusing temperature and process speed during an imaging operation. Upon receipt of a command to commence imaging, a controller operates a heater to heat the fuser assembly to a first temperature less than the fusing temperature and operates a motor to rotate the fuser assembly at a speed lower than the process speed to prevent overheating the heated and backup members. Before a first media reaches the fusing nip, a speed of the motor is increased to the process speed to properly advance the media through the nip at the process speed. Upon the first media arriving at the fusing nip, the controller increases the temperature of the heater to a second temperature greater than the first temperature to prevent cold offset.
