3. Bottom Pick-Up Mode
a. Operation
When the Copy Start key is pressed while
originals are set on the originals tray, the
following takes place:
1) Pick-Up Separation
The pick-up stopper plate is brought down
to move down the paper retaining plate on
the stack of originals, and the last page of
the stack is picked up.
Note that, after pick-up, the original is
moved between the separation belt and the
feeding roller to prevent double feeding.
Caution:
The paper retaining plate is always
brought down when picking up the first
original. For the second and subsequent
originals, the retaining plate is brought
down only when pick-up fails because of
slips (of the pick-up roller) or the like
(i.e., the pick-up sensor S7 does not
detect an original within 500 msec after
the pick-up sensor has turned on) so as to
improve feeding performance.
2) Arching
The original is butted against the
registration roller so that it arches.
