Cassette Feed; Paper Feed System - Ricoh FT2260 Service Manual

9.2 CASSETTE FEED

9.2.1 Paper Feed System

The cassette uses a feed roller and
friction pad paper feed system.
When the feed roller [A] starts turn-
ing, it forces a single sheet of paper
across the friction pad [B]. The
relay roller [C] takes over paper
feed when the paper reaches it.
When the trailing edge clears the
leading edge of the paper stack [D],
the feed roller catches on the next
sheet and starts moving it forward.
The feed roller stops turning when
the trailing edge of the first sheet
leaves the feed roller. The leading
edge of the next sheet is then held
ready for feeding between the fric-
tion pad and feed roller.
Sometimes sheets of paper tend to
stick together (due to, for example,
static electricity, poorly cut edges,
etc.). When this happens, two
sheets may feed between the feed
roller and friction pad. However, the
coefficient of friction between the
friction pad and lower sheet is much
greater than that between the two
sheets of paper. So, the top sheet
slips through while the lower sheet
is held by the pad.
The friction pad holder [E] is
mounted on one end of the swivel
plate with a swivel screw; so, it
automatically applies even pressure
against the feed roller and the copy
paper. The pressure is provided by
the pad pressure spring [F] under-
neath the swivel plate. When the
release lever is lowered the pad
pressure is released.
