Feed-In Unit Mechanism - Ricoh FT5540 Service Manual

3. 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 [A]. This causes the pick-up roller [B] to drop onto the
original(s). At the same time, the DF CPU energizes the original stopper solenoid [C] to retract
the stopper claws [D].
In ADF mode, the original stopper claws stay underneath the original feed table until all the
originals have been fed in. In SADF mode, the stopper claws rise for each original.
The DF CPU turns on the feed-in motor [E] 200 ms after energizing the solenoids. This starts
turning the feed rollers [F] and the pick-up rollers.
