Reversal - Canon FY8-13FW-000DADF-A1 Service Manual

E. Reversal
1. Operation
Reversal is executed only in bottom pick-
up mode; it may be either from the first side to
the second side, or from the second side to the
first side. (Since the same mechanism is
involved, the discussions herein will be on
reversal from the first side to the second side.)
1) Picking Up for the 1st Side
An original is moved from the original tray
to the copyboard glass.
2) Reversal/Feeding
The feeding
counterclockwise to reverse/feed the
original on the copyboard glass.
3) Reversal/Delivery Switching
The paper deflecting solenoid (SL3) is
turned on to open the paper deflecting plate
so that the original is moved back to the
copyboard glass, reversing the original.
When the second side of the original is set
on the copyboard glass, the scanner starts
to move forward.
While the scanner is moving in reverse, the
original is reversed once again so that its
first side is set on the copyboard glass.
When the 1st side of the original has been
copied, the original is moved for delivery.
