Single-Sided Original Feed - Ricoh FT5540 Service Manual

2.2 SINGLE-SIDED ORIGINAL FEED

- Feed-in -
The DF CPU energizes the stopper and pick-up solenoids, and then turns on the feed-in
motor. The feed [A] and friction rollers [B] separate and feed an original to the registration
rollers [C].
A short time after the original reaches the registration rollers, the DF CPU turns on the belt
motor and energizes the registration solenoid. Original skew is corrected by the time lag. The
belt [D] then feeds the original to the exposure glass, while the CPU counts the pulses of the
belt motor encoder. At the proper time, the CPU stops the belt motor.
- Feed-out -
When the DF CPU receives the feed-out signal from the copier, it turns on the feed-out motor.
When the exit sensor [E] is deactuated by the trailing edge of the original, the CPU reduces
the speed of the feed-out motor to feed the original out completely. This stacks the originals
neatly.
