4) Jam duplex (Jam in duplex area)
* Jam duplex occurs when printing the reverse
side of the paper during duplex printing. After
printing the front side the duplex solenoid must
operate in order to feed the paper back into the
duplex path. If the solenoid fails paper may be
stuck in the exit roller and is not fully elected
into the exit tray
* If the duplex solenoid operates paper is fed
back into the machine. If the leading edge of
the paper does not reach the feed sensor in a
certain time then Jam Duplex occurs.
- This can be cause by paper being jammed
in the duplex path area.
5) Jam MPF
* Paper could not be picked up from the MPF tray.
* After pickup, a paper has been fed, but it
doesn't reach the feed sensor in a certain time.
* Feed sensor is faulty and does not detect paper.
