Jams in the fuser and transfer area
Table 7-15 Causes and solutions for fuser delivery delay jams
Cause Solution
The lever for the loop-sensors (loop 1 and loop
2) is not set correctly.
Check the loop-sensor lever and place it in the correct position. If the jam
persists, replace the fuser. See
Fuser on page 179.
The spring of the fuser-delivery-sensor lever is
unhooked.
Check the spring of the fuser and right-door sensor levers and place them in
the correct position. If the jam persists, replace the fuser. See
Fuser
on page 179.
The fuser-delivery-sensor lever is damaged Replace the fuser. See Fuser on page 179.
Poor contact with the fuser-delivery connector Reconnect the connectors of the fuser-delivery media-feed sensor (SR5) (J45),
intermediate (J95) and the DC controller PCA (J123).
The fuser-delivery sensor is defective Check the fuser-delivery sensor with the sensor monitor mode. If the sensor is
defective, replace the sensor (SR5).
Poor contact of the fuser-motor connector
(M2)
Reconnect the connectors of the fuser motor (J15) and the DC controller PCA
(J117).
The fuser motor is defective Execute the fuser-motor driving test in the actuator-drive mode. If the motor is
defective, replace the fuser motor (M2).
The fuser pressure release sensor (SR7) is
defective.
Execute a manual sensor test to verify the sensor is working by manually
toggling the sensor. Check "H" to see if the value changes. If not, replace the
sensor. See
Manual sensor test (special-mode test) on page 325.
Table 7-16 Causes and solutions for wrapping jams
Cause Solution
The fuser roller or pressure roller is dirty Execute a fuser roller cleaning.
The guide of the fuser delivery unit is dirty Clean the guide.
The fuser roller or the pressure roller is worn
or deformed
Replace the fuser. See Fuser on page 179.
Table 7-17 Causes and solutions for fuser delivery stationary jams
Cause Solution
The fuser roller or pressure roller is worn or
deformed
Replace the fuser. See Fuser on page 179.
The fuser delivery roller is deformed
The gear of the fuser delivery roller is
damaged
The fuser delivery sensor lever is set
incorrectly or damaged
Check the sensor lever to make sure it is set correctly. If it is damaged, replace
the fuser. See
Fuser on page 179.
The spring of the fuser delivery sensor lever is
unhooked
Check the spring and place it in correct position.
