Abstract
A fuser roll nip sheet sensing scheme detects the torque spike of a fuser roll motor when paper is entering the nip region and uses that spike to signal a speed change to the motor to thereby control the motion of the paper. The nip sheet sensing scheme is used for paper position/timing and for single pass duplex fusing.
