Abstract: 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.

Abstract: An improved laser printer is provided that keeps its fuser at a standby temperature that is somewhat raised above the ambient temperature, which allows the printer to operate more quickly (to begin printing the first page) when a print job arrives at the printer. The time needed to raise the fuser's temperature is minimized, so that other printer operations become the determining factor in the time to first print parameter. The electrical energy that energizes the fuser is provided in a form that prevents light flicker, by use of AC waveform phase control, or by use of integer half cycle control. The present invention uses closed-loop feedback control, and the type of controller is a PID controller.
