Document Feeding/Delivery
■
Basic Operation
After completion of stream reading on the document glass, the document is delivered to the
document delivery unit as discussed below.
Document feed/delivery
After moving past the reading position, the document is fed by the read roller 2 and delivery
reversal roller driven by the pickup/feed motor (M1) which is turning in the reverse direction.
The delivery reversal roller is normally pressurized; the Shift solenoid (SL2) turns on only
when the document is reversed for duplex printing.

Release Operation
When a document is read, the read roller 1 (lower driven rollers) are pressurized/released to
prevent the training edge of the document from swaying.
After separation of the document, the read roller 1 (lower driven rollers) are pressurized by
the Release motor (M2) during formation of a registration loop.
After lapse of the predetermined time since turning off of the document trailing edge
registration sensor, the Release motor is driven to release the read roller 1 (lower driven
rollers).
