Transfer Belt Drive Mechanism
After the main motor switches on during printing, the transfer belt contact clutch [A] switches on after a
specified interval and the cam [F] makes a half-turn to raise the contact lever [E] and bring the transfer belt
[D] into contact with the drum.
The actuator [C], on the same axis as the cam, and the transfer belt position sensor [B] detect whether the
drum and transfer belt are in contact.
When the main motor is off, or when the ID sensor pattern is being measured, the transfer belt unit separates
from the drum. The ID sensor pattern must not be transferred to the belt. Also, the transfer belt and drum
must not remain in contact for too long, to prevent contamination of the drum with oil or other foreign
material from the transfer belt.
