3. OPERATIONS AND TIMING
F. Making Overlay Copies
(copying on 1st side)
The feeding path for copying on the first side of
an overlay copy is formed shifting up the No. 1
paper deflecting plate by a solenoid (SL3) and
pulling back the No. 2 paper deflecting plate by a
solenoid (SL2).
The No. 1 paper deflecting plate is shifted up
about 1.6 sec after copy paper reaches the pre-
registration paper sensor (Q30).
The No. 1 paper deflecting plate serves to
send copy paper to the No. 2 feeding assembly
and then to the duplexing unit.
The sub feeding roller is moved down on the
stack of copy paper each time copy paper is sent
for copying on the first side, thereby making sure
that the sheets are stacked properly.

The sub roller lowers about 1 sec after the No.
2 feeding assembly inlet sensor (Q12) detects
copy paper.
In continuous copying, the pick-up assembly
locking solenoid (SL8) is released (turned OFF)
after the first sheet of copy paper has been fed by
the sub feeding roller so that the first sheet of the
stack is fed somewhat in advance; the pick-up
assembly locking solenoid (SL8) is locked (turned
ON) to operate the shutter guide for the second
and subsequent sheets of copy paper.
The duplexing unit is capable of accommodat-
ing 50 sheets (50 sheets of A4, B5, LTR in hori-
zontal feeding; 25 sheets of thick paper).
