Theory of operation Ver. 1.0 May 2008
(1) Fusing deceleration (low speed):
• When the media loop length is small, the actuator of the media loop sensor is pushed up
a small amount and the sensor is unblocked. When the sensor is unblocked, the fusing
speed is decelerated.
(2) Fusing acceleration (high speed):
• When the media loop length is large, the actuator of the media loop sensor is pushed up
a large amount and the sensor is blocked. When the sensor is blocked, the fusing speed
is accelerated.
