Delivery; Expansion Paper Feeder; Duplex Unit - Lexmark C920 Service Manual

Delivery

After completing the fusing process, paper is discharged from the printer. The delivery sensor detects the paper
condition, and the FU/FD deflector switches between the face-up and face-down paper delivery. The paper from
the fuser pulls down the sensing lever turning on the delivery sensor (photo interrupter). If the delivery unit
remains on longer than specified, the printer controller determines that the printer is jammed, and the paper
delivery flap lever switches to either face down or face up.

Expansion paper feeder

The optional expansion paper feeder can be installed at the lower part of the main unit. Including the main unit,
up to five layers of cassettes can be used for cassette paper feeding.

Duplex unit

A duplex unit can be installed into the printer to allow two-sided printing.
Once the media has exited the fuser and is partly out of the top exit rollers, feeding is stopped and then reversed,
and the media is directed into the duplex unit.
Paper fed into the duplex unit stops and synchronizes while the center position of the media is corrected by the
operation of the side guide plate. Paper is then re-fed and is delivered to the normal feeding path on the right
side of the printer.
