Paper Feed - Ricoh FT5540 Service Manual

10. PAPER FEED

Paper feeds from either the first or second feed station [A] or from the manual feed table [B].
The capacity of each cassette is 500 sheets. One of the two optional large capacity trays
(1,000 or 2,500 sheets) can be installed in the second feed station. Even more paper is
provided with the cassette bank option. The cassette bank can hold a third and a fourth
cassette [C]. These cassettes are the same as those of the first and second paper feed
stations. The maximum paper capacity with both the cassette bank and the 2,500 sheet large
capacity tray installed is 4,000 sheets.
This copier uses three rollers for paper feed: a pick-up roller [D], a feed roller [E], and a
separation roller [F]. The bottom plate [G] inside the cassette is automatically lifted up when
the cassette is inserted into the copier. It stops when the paper stack pushes up the pick-up
roller.
Rotation of the pick-up roller drives the top sheet of paper from the cassette to the feed and
the separation rollers. The feed and separation rolIers then take over the paper drive. If more
than one sheet is fed by the pick-up roller, the separation roller rotates in the opposite
direction and prevents all but the top sheet from passing through to the registration/relay
rollers.
The feed roller for the first paper feed station feeds the top sheet directly to the registration
rollers [H]. The feed roller of the second feed station, however, feeds the top sheet to a set of
relay rollers [I], which then feed the sheet to the registration rollers.
