Conveying sensor non
arrival jam (J1503/
J1504)
SM conveying sensor
2 stay jam (J3415,
J3416, J3417)
1. Check to see if the
actuator is operative
without hinderance.
Re-assemble or replace the actuator's return spring.
2. Perform U030 to check
the operation of the
motor.
Check the transmission
of the gear drive using
U032.
* : Check the convey-
ing roller rotates and
is movable in the
direction of thrust
without hinderance.
(see page 1-3-36)
If the roller won't rotate without hinderance, loosen
the screws for adjusting the position (at the gear train
bracket) to mount the driving gears, and tighten so
that a gap between the gears and frame is
eliminated.
Loop sensor non
arrival jam (J4101,
J4102, J4103, J4104,
J4105, J4106, J4107)
1. Check no wrinkles are
observed at the sluck of
paper during paper
feeding.
Adjust the cursors to the size of the paper.
(If paper is fed askew, perform a skew cancellation
adjustment of the width adjuster cursor.) (see page 1-
5-123)
2. Check that the paper is
entirely loaded inside
the cassette without
being skewed.
Reload paper.
Fuser eject sensor
stay jam (J421X)
Ejection-full sensor
non arrival jam
(J460X)
Inversion sensor non
arrival jam (J470X)
1. If paper jam occurrs at
the feedshift guide in
the eject unit, check if
the guide is operative
without hinderance.
If the distance between the housing and the feedshift
guide is too small for the guide to move without
hinderance, replace the eject unit.
2. Perform U031 to check
if the eject sensor does
not show a false
detection.
(see page 1-3-35)
Replace the defective eject sensor or the eject unit.
