Jam causes and solutions
Jams in the output bin
Table 3-43 Causes and solutions for delivery delay jam
Cause Solution
The output-bin full sensor flag is damaged. Examine the output-bin full sensor flag for damage. If the flag is damaged, replace
the paper delivery assembly.
See Output-bin-full sensor (PS10) for troubleshooting information.
Poor contact of the output-bin full sensor
connector.
If the product was recently repaired, check and reconnect the connector (J181) on
the DC controller PCA and the intermediate connector (J743).
The output bin full sensor (PS10) is defective. Check the output bin full sensor (PS10) using the manual sensor test. See Output-
bin-full sensor (PS10) for troubleshooting information.
Poor contact of the fuser-motor (M4) connector. Reconnect the connectors of the fuser motor (J516), and the DC controller PCA
(J81).
The fuser motor (M4) is defective. Execute the fuser-motor driving test in the component test (see Component test ).
If the motor is defective, replace the fuser motor (M4).
Jams in the fuser and transfer area
Table 3-44 Causes and solutions for fuser delivery delay jams
Cause Solution
The fuser-output sensor connctor has a poor
connection.
Reconnect connector J131 on the DC controller PCA.
The fuser-output sensor (PS6) is defective. Check the fuser-output sensor (PS6) with the manual sensor test. See Fuser output
sensor (PS6). If the sensor is defective, replace the fuser.
Table 3-45 Causes and solutions for wrapping jams
Cause Solution
The fuser roller or pressure roller is dirty. Print a cleaning page. See Process a cleaning page.
The fuser roller or the pressure roller is worn or
deformed.
Replace the fuser.
The output bin full sensor has a poor connection. Reconnect the connector J181 on the DC controller PCA, and the intermediate
connector J743.
The output bin full sensor is defective. Run the manual sensor test to verify the output bin full sensor is functioning
properly. See Output-bin-full sensor (PS10). If not, replace the fuser gear
assembly.
