PAPER JAM
Problem
Type of jam
Cause
Temp measure
Jam at power on
Paper stuck
Paper feed sensor or
paper eject sensor is
turned on.
Remove the paper inside
the printer. If there is no
paper, check the
suspect sensors
referring to note and
clear the problem.
Top of paper stopped
at 20mm from the
fixing unit.
Paper feed roller
rotated twice.
No paper
Paper feed sensor is
not turned on.
Check paper feed
sensor motion referring
to note and clear the
problem.
Top of paper stopped
at 250mm from the
fixing unit.
Next paper is not fed.
Jam caused by paper
length detected as
longer than 400mm (16
inches).
Paper feed sensor is
not returning properly,
and is not turned off.
Check paper feed
sensor motion referring
to note and clear the
problem.
Top paper stopped
between the paper
feed roller and the
pick-up roller.
Jam caused by paper
length detected as
shorter than 80mm.
Paper feed sensor
was turned off early.
Malfunction of
actuator or hardware
noise.
Check sensors referring
to note and clear the
cause of the problem.
Paper was fed approx.
20mm from the pick-
up roller.
Jam caused by a paper
feed delay.
Due to paper dust or
rubber of the pick-up
roller wear, paper was
not fed in at the
proper timing.
Remove the paper dust
attached to the pick-up
roller. If the rubber is
worn out, replace it with
new one.
Top of paper stopped
at 17mm from the
contact point of the
heat roller and
pressure roller.
Jam caused by the
paper sensed as not
being ejected from the
paper eject sensor.
Paper eject sensor
does not work
properly and is not
turned off.
(single printing)
Check the sensor motion
referring to note and
clear the problem.
Jam occurred after
ejecting paper.
Same as above.
Same as above.
(continuous printing)
Same as above.
Top of paper stopped
at 20mm from the
fixing unit.
1. Cover open
2. Bug
1. Cover is not closed
properly.
2. Bug
1. Check if the drum unit
is installed correctly.
2. Please inform BIL.
Note: How to check the sensors
(1) Open the cover.
(2) Power on the printer while pressing the panel switch.
(3) Release the panel switch.
(4) Press and release the panel switch.
Results:
*Alarm Lamp is ON = Paper feed sensor is turned ON
*Drum Lamp is ON = Paper eject sensor is turned ON
