Jam 2 - Ricoh B173 Service Documentation

4.4.4 JAM 2

Description
1. Recording paper is jammed in front of or
inside the fuser.
2. Recording paper is stuck in the transfer
roller and in the fuser just after passing
through the Actuator-Feed.
Check and Cause
Exit sensor is defective if the paper is
completely fed out of the printer, but
Jam 2 occurs.
• After the paper is completely discharged,
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.
If the paper is rolled in the fuser roller:
• This occurs when a guide claw breaks away
or becomes deformed.
• It occurs when the guide spring breaks
away or becomes deformed.
• It occurs when the heat-roller or pressure-
roller gets too much toner powder.
Paper is accordion and jams in fuser.

PAPER FEEDING PROBLEMS
Solution
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 if burrs occur in the assembly part
of the actuator. Check if the actuator is
smoothly operated.
• Check if unwanted matters and wire got
caught in the actuator exit's operation.
If the paper is stuck in the fuser,
disassemble the fuser and remove the
jammed paper. Then clean the
surface of the pressure roller with dry
gauze.
Remove the jammed paper after you
disassemble the fuser: Clean the
surface of the pressure roller with dry
gauze.
• Remove the toner particles stained on
the rib.
• Check the assembly and the
performance of the exit.
