Cause Solution
Poor contact of the residual media jam
detective sensor connector
Run the sensor test in the sensor monitor mode to verify which sensor detects
the media. Reconnect the following corresponding sensor connector:
●
TOP sensor (SR8): Connector (J109) on the DC controller PCA
●
Fuser delivery sensor (SR5): Intermediate connector (J95) and connector
(J123) on the DC controller PCA
●
Loop sensor 1 or 2 (SR14 and SR15): Connector (J139) on the DC
controller PCA
●
Duplex re-pickup sensor (SR22): Connector (J107) on the DC controller
PCA.
The residual media jam detective sensor is
defective.
Run the sensor test in the sensor monitor mode to verify which sensor detects
the media. Replace the following corresponding part:
●
TOP sensor (SR8): Replace the registration assembly. See
Registration
assembly on page 233.
●
Fuser delivery sensor (SR5): Replace the fuser. See
Fuser
on page 179.
●
Loop sensor 1 or 2 (SR14 and SR15): Replace the fuser. See
Fuser
on page 179.
●
Duplex re-pickup sensor (SR22): Replace the MP tray pickup assembly.

Cause Solution
The registration roller is worn or deformed. Replace the secondary-transfer unit.
The spring of the registration shutter is
unhooked.
Check the spring and place it in correct position.
Poor contact of the pickup motor drive
connector
Reconnect the connectors of the registration motor (J6), intermediate, and the
DC controller PCA (J131).
The pickup motor is defective. Execute the pickup-motor driving test in the actuator-drive mode. If the motor is
defective, replace the pickup motor. See
Pickup motor on page 253.
The cassette pickup roller is worn or
deformed.
Replace the cassette pickup roller. See Pickup roller (Tray 2) on page 180.
The cassette separation roller is worn or
deformed
Replace the cassette separation roller. See Separation roller (Tray 2)
on page 183.
Poor contact of the TOP sensor connector Reconnect the connector (J109) on the DC controller PCA.
The TOP sensor is defective. Run the sensor test in the sensor monitor mode to verify that the TOP sensor is
functioning properly. If it is not, replace the registration assembly. See
Registration assembly on page 233.
Poor contact of the cassette pickup solenoid
drive connector
Reconnect the connector (J140) on the DC controller PCA.
The cassette pickup solenoid is defective Run the solenoid drive test in the actuator drive mode to verify that the cassette
pickup solenoid is functioning properly. If it is not, replace the cassette-pickup
drive assembly. See
Cassette-pickup drive assembly on page 256.
