This copier uses an FRR paper feed system using three rollers.
Pick-up Roller
The pick-up roller [A] is not in contact with the paper stack before it starts feeding
paper. Shortly after the Start key is pressed, the pick-up roller drops down and
feeds the top sheet between the feed [B] and the separation rollers [C]. At almost
the same time that the leading edge of the paper arrives at the feed roller, the pick-
up roller lifts off the paper stack so that it does not interfere with the operation of
the feed and separation rollers. The feed and separation rollers then take over the
paper feed process.
Feed and Separation Rollers
There is a one-way bearing inside the feed roller so it can turn only in one direction.
The separation roller turns in the opposite direction of the feed roller. The
separation roller, however, has a slip clutch (torque limiter clutch), which allows it to
turn in either direction depending on the friction between the rollers. The separation
roller solenoid keeps the separation roller in contact with the feed roller.
