ABSTRACT:
Disclosed are methods of controlling a speed of a fuser cleaner web in a fuser apparatus, and the corresponding fuser apparatus. The method utilizes a fuser cleaner web for cleaning a fuser roll and being disposed between the fuser roll and a web nip roll, the fuser cleaner web being unwound from a web supply roll and wound onto a take up roll, the take up roll being driven by a motor. The method determines an angular displacement of the motor from a start of the fuser cleaner web being unwound from the web supply roll, and controls a speed of the motor to maintain a substantially constant fuser cleaner web speed, wherein the speed of the motor is controlled based on the determined angular displacement of the motor and a changing diameter of the take up roll.
