4) JAM 2
Description: 1. Recording paper is jammed in front of or inside the fuser.
2. Recording paper is stuck in the discharge roller and in the fuser just after passing through the
Actuator-Feed.
2. If the paper is
rolled in the Fuser Roller:
1. If the paper is
completely fed out of the printer,
but Jam 2 occurs : Exit sensor is defective.
• After the paper is completely discharged, actuator
Exit should return to the original position to shut the
photo-sensor. Sometimes it takes longer
hour than it should and does
not return.
• This occurs when a Guide claw is broken
away or transformed.
• It occurs when the Spring of a Guide claw is broken
away or transformed.
• It occurs when the Heat-Roller or
Pressure-Roller is seriously
contaminated with
the toner.
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 matter and wire
get caught in the actuator exit's
operation.
If the paper is stuck in the fuser :
disassemble the fuser and remove
the jammed paper, and clean the
surface of the pressure roller with
dry gauze.
