15.3.3 Reversal exit operation
In the double-sided copy mode, the reversal exit operation is carried out when the second side is output
if the following conditions are met:
Conditions: The 1st of several copies of two or more odd-numbered originals made in the one-sided and
double-sided modes using the ADF. Or, when one copy is made.
By the reversal exit operation, the double-sided copy sheets are detected by the body aligning switch
when the sheets arrive at the aligning roller on the copier, and the ADU/exit switching gate are positioned
in the direction of the paper stack section by solenoid. Next, the double-sided copy sheets are fed inside
the ADU inlet guide by During this operation, the leading edge of the paper is detected by the reversal
switch, and the inlet/reversal roller rotates in the forward direction to transfer the paper to the ADU stack
section.
When the paper passes through the reversal gate, and the trailing edge of the paper passes the reversal
switch, the inlet/reversal roller rotates in the reverse direction by the reverse direction clutch, and the
paper is guided to the reversal guide section by the reversal gate. After the paper is guided to the
reversal guide section, it is output to the copy tray by the exit roller.
1) The reversal switch detects the leading and trailing edges of the paper passing through the reversal
gate. It is also used for detecting paper jams.
