Description of Mechanisms
TRANSFER BELT CLEANER SEPARATION
The transfer belt cleaner is separated by turning on and off of the Cleaner Pressure Flapper
Solenoid (SL4) which activates rotation of the cam on the printer body.
(Driven by the main motor)
The cam driven on the printer body is brought into contact directly with the cleaner housing
to estrange the transfer belt cleaner. As the cam rotates and the belt cleaner position
detection sensor (PC9) is turned off, the transfer belt cleaner is detected to be separated.
