Description:
There is an accordian jam in front of or inside the
fuser.
There is an accordian jam stuck in the discharge
roller and in the fuser, just after passing the feed

exit sensor is defective:
■
After paper passes the exit sensor, the flag should
return to its normal position. The flag may stick or
return too slowly due to contamination or foreign
objects obstructing its path.

■
The guide claw is damaged.
■
The spring on the guide is damaged.
