8.1.7 PAPER MISFEED - JAM: TRAY 2 (J003)
SERVICE CENTER CALL RESPONSE
Transport jam occurred. (Tray 2)
When the paper was feed from Tray 2, the
registration sensor detected the leading edge, but
the trailing edge sensor did not detect the trailing
edge because the stopped in the paper path.
Ask the operator to try the following procedures
to remove and prevent paper transport jams when
feeding from Tray 2. Also, check inside the printer
and Tray 2 for paper. If you find paper inside the
printer or tray, remove it, and then press the
[Paper Feed] key.
(1) Check for paper inside the printer. Paper
inside the printer can cause double feeding.
Switching to a different type of paper and
changes in the environment can also cause
double-feeding. Do not use continuous form
feed paper; if you use such paper separate
each sheet before loading. The printer is
guaranteed for fewer than 1 jam per 1,000
sheets when using approved paper.
(2) Check the type and condition of the paper,
then do the following procedures.
