III. CONTROLLING THE REGISTRATION ROLLER
A. Outline
The registration roller rotates when the registration cam found under the copyboard
glass pushes the lever* while the copyboard is moving forward; see Table 3-2 and
Figure 3-28.
* Frees the claw that holds the control ring.
The registration roller stops when the pick-up solenoid (PC420/430/FC220) or the
registration solenoid (PC400/FC200) goes ON to set the claw to the control ring.
