(2) Items and corrective actions relating to the device that will cause paper jam

Jam types
No-paper-feed jam or
the leading edge of
paper is curled back at
the position of the
roller
(J0501,J0502,
J0503,J0504, J0509)
Check description
1. Check if the jammed
paper or the printed
paper has a tear
caused by the roller at
its leading edge.
2. Check abrasion and
paper dusts on the feed
roller and forward
rollers.
3. Perform U032 to check
the pickup roller and
paper feed roller are
rotating.
4. Check that the
conveying force of the
pickup roller is
sufficient.
5. Check the film is
sufficiently protruded in
front of approching the
feed roller and the
nip.(Too wide a gap
against the feed roller.)
6. Check the separation
roller is not disturbed as
a driving component is
in contact with the
frame during the
separation roller is in
motion.
7. Depress the release
lever to release the
pressure of the primary
feed rollers to check
that the retard holder
falls.(The pressure by
the retard roller to the
feed roller is
decreased.)
Corrective measures
Replace the paper feed roller.(Service life of rubber
roller is 150k.)
Increase the spring pressure to pinch the separation
rollers if the component is undue to its expected
life.Replace the spring.
Clean the paper feed roller and the pickup roller. Or, if
not amended, replace.
If disconnected or or stained, replace the primary
paper feed clutch.
Increase the conveying force during paper pickup by
increasing the spring load of the pickup roller.
Amount of protrusion of film in approaching (Gap: 0.2
- 0.5 mm) must be maintained after adjustment.
If it gets in contact, replace the primary paper feed
unit.
Modify mounting the retard holder fixing plate.
