Overview
Fixing/delivery system consists of the xing lm unit, pressure roller and delivery roller etc.
These rollers are driven by the main motor (M1).
The paper that toner is transferred to are heated by the xing heater of the xing lm unit and
pressured by the pressure roller.
The paper that toner is fused on is delivered from the xing assembly, detected by the xing
delivery sensor (PS701) and the paper width sensor (PS702), and then delivered to the
delivery tray by the delivery roller.
