2.8 FIXING UNIT/DELIVERY SYSTEM

2.8.1 Overview/Configuration

2.8.1.1 Overview

0008-0451

The fixing/delivery system consists of the fixing film unit, pressure roller, face-down delivery roller, and the like. Its rollers are driven by the main motor

(M1).

When print paper carrying a toner image arrives in the fixing assembly, the machine uses the heat from the fixing heater and the pressure from the pressure

roller to permanently fuse the toner with the fibers of the print paper before it moves out of the fixing assembly.

Once outside the fixing assembly, the print paper is delivered to the delivery tray by the work of the face-down delivery roller upon detection by the delivery

sensor (PS803).
