Document Reversing
■
Basic Operation
There are two types of document reversal operation: one that is performed from the top to the
reverse side of the document and the other that is performed from the reverse side to the top
of the document.
Since the basic operation methods are identical, only the reversal operation performed from
the reverse side to the top is discussed below.
Top side pickup
The pickup/feed motor (M1) drives the read roller 1 and platen roller to scan the surface of
the document.
After completion of scanning, the read roller 2 and delivery reversal roller feed the document
to the delivery unit.

Reversal/feed 1
When the trailing edge of the fed document moves past the delivery reversal sensor (SR3),
the pickup/feed motor stops. Immediately after this, the pickup/feed motor starts turning in the
reverse direction to feed the document to the registration roller, then it stops. At this time, the
pressurization solenoid (SL2) turns on to release the delivery reversal roller.

Reversal/feed 2
The pickup/feed motor turns to feed the document to the reading wait point and stops.
Thus, the document has been reversed. Next, the document is picked up again and its
reverse side is read, turning off the pressurization solenoid. After this, the
document is reversed again, fed, and then delivered.
