Cleaning Mechanism - Ricoh G147 Service Manual

6.13.7 CLEANING MECHANISM

The cleaning roller [A], in constant contact with the pressure roller [B], collects toner and
paper dust from the surface of the pressure roller. Because the cleaning roller is metal, it can
collect adhering matter better than the pressure roller, which is coated with Teflon.
6.13.8 FUSING TEMPERATURE
Fusing Temperature Components
The fusing unit has two fusing lamps: the first fusing lamp (center: 650W) [A] heats the
center of the fusing roller, and the second fusing lamp (ends: 550W) [B] heats both ends of
the hot roller. This arrangement ensures even heat on all surfaces of the roller.
In order to control the temperature of the roller, two high response thermistors are attached
to the unit, one near the center [C] and one at the end [D] of the hot roller.
