PAPER FEED AND REGISTRATION
1. OVERVIEW
Paper feeds from either the cassette [A] or from the manual feed table [B]
The capacity of the cassette is 250 sheets, and up to 50 sheets can be set
at once on the manual feed table.
This copier uses three rollers for paper feed: a pick-up roller [C], a feed
roller [D], and a reverse roller [E]. The bottom plate [F] inside the cassette
is automatically lifted up when the Start key is pressed or when the copier
changes from the warm-up condition to the ready condition. It stops when
the paper stack pushes up the feeler of the paper lift sensor.
Rotation of the pick-up roller drives the top sheet of paper from the cassette
to the feed and the reverse rollers. The feed and reverse rollers then take
over the paper drive. If more than one sheet is fed by the pick-up roller, the
reverse roller rotates in the opposite direction and prevents all but the top
sheet from passing through to the registration roller.
