Feed-In Unit Mechanism - Ricoh FT4430 Service Manual

FEED-IN UNIT MECHANISM

After an original is inserted into the feed-in unit and the Start key is pressed,
the DF CPU energizes the pick-up solenoid [S01-7] and the pick-up roller [A]
drops onto the top of the original(s). At the same time, the DF CPU energizes
the original stopper solenoid [Sol-1 O] to retract the stopper claws [B].
In ADF mode, the original stopper claws stay underneath the original feed
table until all the originals have been fed. In SADF mode, the stopper claws
rise up for each original.
200 ms after energizing the solenoids, the DF CPU turns on the feed-in motor
[M-14] which rotates the feed and pick-up rollers.
