Check description
1. Check to see if the
actuator is operative
without hinderance.
2. Check the operation of
the sensor.
3. Check if the PF paper
feed clutch rotates
following the other
component.
4. Check if the conveying
guide is twisted to be
mounted.(If the
mounting parts of the
guide is floated, the
actuator won't protrude
sufficiently.)
5. Check no wrinkles are
observed at the sluck of
paper during paper
feeding.
1. Check to see if the
actuator is operative
without hinderance.
2. Check the operation of
the motor.
Check the transmission
of the gear drive .
* : Check the convey-
ing roller rotates and
is movable in the
direction of thrust
without hinderance.
1. If paper jam occurrs at
the feedshift guide in
the rear cover assem-
bly, check if the guide is
operative without
hinderance.
2. Check if the eject
sensor does not show a
false detection.
Corrective measures
If it won't operate without hinderance, re-assemble or
replace the actuator's return spring.
If the sensor is inoperative, replace.
If stained, replace the clutch.Re-assmeble the clutch
so that it is not continuously energized. (Change of
wirings, etc.)
If the bracket is twisted to be mounted, remove the
screw fixing the conveying guide and properly mount
the bracket in the right position and fix again.
Adjust the cursors to the size of the paper.
Re-assemble or replace the actuator's return spring.
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.
If the distance between the housing and the feedshift
guide is too small for the guide to move without
hinderance, replace the rear cover assembly.
Replace the defective eject sensor or the fuserunit.
