Jam causes and solutions
For locations of jam sensors, see Jam detection on page 55.
Jams in the output bin
Table 3-16 Causes and solutions for delivery delay jam
Cause Solution
The output-bin full sensor flag is damaged. Replace the paper delivery assembly. See Delivery assembly on page 145.
See
Manual sensor test (special-mode test) on page 246 for troubleshooting
information.
Poor contact of the output-bin full sensor
connector.
Reconnect the connectors of the output-bin full sensor (SR6) (J47) to DCC PCA
(J123).
The output bin full sensor (SR6) is defective. Check the output bin full sensor (SR6) using the manual sensor test. See
Manual sensor test (special-mode test) on page 246. The output bin full sensor
is letter F in the sensor test. Toggle the sensor to determine if the value changes
for "F". If the value does not change, replace the sensor.
Poor contact of the fuser-motor (M2)
connector.
Reconnect the connectors of the fuser motor (J117), (J15), and the DC
controller PCA (J105).
The fuser motor (M2) is defective. Execute the fuser-motor driving test in the actuator-drive mode. If the motor is
defective, replace the fuser motor (M2).
Jams in the fuser and transfer area
Table 3-17 Causes and solutions for fuser delivery delay jams
Cause Solution
The fuser-delivery-sensor flag is damaged. Replace the fuser. See Fuser on page 85.
Poor contact with the fuser-delivery connector. Reconnect the connectors of the fuser-delivery sensor (J48) and the DC
controller PCA (J127).
The fuser-delivery sensor (SR5) is defective. Check the fuser-delivery sensor (SR5) with the manual sensor test. See
Manual sensor test (special-mode test) on page 246. If the sensor is defective,
replace the sensor.
Table 3-18 Causes and solutions for wrapping jams
Cause Solution
The fuser roller or pressure roller is dirty. Create and use a cleaning page. See Cleaning page on page 306.
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 85.
The lever for the output bin full sensor on the
face-down tray is set incorrectly or is
damaged.
Set the lever correctly. If the lever is damaged, replace the delivery assembly.
See
Delivery assembly on page 145.
The spring on the lever for the output bin full
sensor on the face-down tray is unhooked.
Reattached the spring.
