3. OPERATIONS AND TIMING
H. Making Two-Sided/Overlay
Copies (copying on 2nd side)
For copying on the second side of a two-sided/
overlay copy, the paper is picked up from the
duplexing unit.
When the Copy Start key is pressed, the re-
pick up motor (M25) turns ON as soon as the re-
pick up clutch (CL6) turns ON. At this time, the
pressure on the copy paper shutter guide is
removed by the pick-up assembly releasing sole-
noid (SL8) to feed a single sheet of copy paper.

The feeding roller then moves the copy paper
as far as the registration roller.
When the original leading edge detection sig-
nal is generated, the registration roller starts to
rotate for copying on the second side.
Since the No. 1 paper deflecting plate remains
in the bottom position, copy paper after fixing is
allowed to move to the copy tray.
