Check and Cause
Solution
1. If the paper is completely fed out of
the printer, but Jam 2 occurs
: Exit sensor is defective.
• After the paper is completely dis
-
charged, actuator Exit should return
to the original position to shut off the
photo-sensor. Sometimes it takes
longer than it should and
does not
return.
2. If the paper is rolled in the Fuser Roller:
• This occurs when a Guide claw is
broken away or transformed.
• It occurs when the Guide slaw spring
is broken away or transformed.
•
It occurs when the Heat-Roller or
Pressure-Roller is seriously contami -
nated with toner powder.
3. Paper is accordion jammed in fuser.
1. Check if the exit sensor actuator is
defective.
• Check if the actuator exit is deformed
(Check if the lever part is deformed
in shape).
• Check whether burrs occur in the
assembly part of the actuator exit or
not and if the actuator is smoothly
operated.
• Check if foreign matters and wire get
caught in the actuator exit's operation.
2. If the paper is stuck in the fuser : dis -
assemble the fuser and remove the
jammed paper, and clean the surface
of the pressure roller with dry gauze.
3. Remove the jammed paper after disas-
sembling the fuser : Clean the surface
of the pressure roller with dry gauze.
• Remove the toner particles stained
on the rib.
• Check the assemblage and perfor -
mance of the exit.
