2.8.1.3 Overview

0025-1175

LBP6000 / LBP6000B

Fixing/delivery system consists of the fixing film unit, pressure roller and delivery roller etc.
These rollers are driven by the main motor (M1).
Toner is transferred on the paper and fused by the heat of the fixing heater on the fixing assembly and by the pressure from the pressure roller, then the paper is
delivered from the fixing assembly.
The paper is detected by the delivery sensor (PS701) and the paper width sensor (PS702), and then delivered to the delivery tray by the delivery roller.

LBP6000 / LBP6000B

Main parts configuration and its purposes inside the fixing assembly are described below.

[5] Fixing film unit

[6] Fixing assembly

- Fixing heater:

This fixing assembly is equipped with 1 heater.

Fixing heater (H1): For heating the fixing film (ceramic heater)

- Thermistor:

This fixing assembly is equipped with 1 thermistor.

Main thermistor (TH1): For controlling the fixing heater temperature (contact type thermistor)

- Temperature fuse:

This fixing assembly is equipped with 1 temperature fuse.

Temperature fuse (TP1): For detecting the fixing heater overheat (non-contact type fuse)

When the heater overheats, the fuse melts to cut the power supply to the heater.
