2 UNIT EXPLANATION
c) ADU paper conveyance
In the two-sided copy mode, the paper finished
with printing on the front side is fed, through the
path under the paper gate, into the paper
reverse/exit section just like paper reverse/exit
operation. Then, the paper is fed to the ADU unit
by paper reverse and eject rollers 1-3. These roll-
ers do not rotate in the opposite direction even
when PS57 detects the trailing edge of the paper,
allowing the paper to be fed to the ADU paper
reversal roller.

tion by paper reverse/exit roller rotation knob
When a jam occurs in the paper reverse/exit sec-
tion, the jammed paper can be removed by open-
