Arch Control - Canon MF735C Series Service Manual

Arch Control

Description
Arch control keeps the appropriate slack on paper to prevent image failure and feed failure.
• If the rotation speed of the Fixing Motor is slower than the rotation speed of the Drum Motor, the slack on the paper becomes
larger.
• If the rotation speed of the Fixing Motor is faster than the rotation speed of the Drum Motor, the slack on the paper becomes
smaller.
The DC Controller detects the slack on paper by the Loop Sensor (SR2), and controls the rotation speed of the Fixing Motor.
Fixing Motor rotates slower
than Drum Motor.
