Duplex Stacking - Ricoh FT4220 Service Training Manual

5. BASIC OPERATION
5.1 FIRST SIDE COPY
When the registration clutch turns on, the duplex gate [A] rotates up to direct
the copy to the duplex unit. The entrance rollers [B] and duplex feed roller [C]
then start to rotate. At the same time, the duplex bottom plate [D] lowers.
5.2

DUPLEX STACKING

After the copy is delivered to the duplex tray [E], the jogger fences [F] move
inward to square the copy stack, then move back 10 mm. After the final copy
is delivered to the tray, the jogger fences remain against the paper stack.
5.3 SECOND SIDE COPY
Soon after the final copy is squared by the jogger fences, the duplex bottom
plate raises up to the final position and the duplex feed rollers start rotating
counterclockwise (front view) to feed the copy to the relay rollers [G]. Second
side copying is then done with the copy following the second feed station
paper path.
