Table 2-38 Causes and solutions for residual paper jams (continued)
Cause Solution
The sensor detecting a residual media jam is
set incorrectly or damaged.
Run the sensor test to verify which sensor detects the paper. Check the sensor
lever to make sure it is set correctly. If it is damaged, replace the following
corresponding part:
●
Registration sensor (SR8): Replace the registration assembly.
●
Fuser output sensor (SR5): Replace the fuser.
●
Fuser loop sensor 1 or 2 (SR14 and SR15): Replace the fuser.
●
Duplexer re-feed sensor (SR22): Replace the MP tray pickup assembly.
The spring of the residual media jam detective
sensor lever is unhooked.
Run the sensor test to verify which sensor detects the paper. Check the spring
of the sensor lever to make sure it is set correctly.
Poor contact of the residual media jam
detective sensor connector.
Run the sensor test to verify which sensor detects the paper. Reconnect the
following corresponding sensor connector:
●
Registration sensor (SR8): Connector (J109) on the DC controller PCA.
●
Fuser output sensor (SR5): Intermediate connector (J95) and connector
(J123) on the DC controller PCA.
●
Fuser loop sensor 1 or 2 (SR14 and SR15): Connector (J139) on the DC
controller PCA.
●
Duplexer re-feed sensor (SR22): Connector (J107) on the DC controller
PCA.
The residual media jam detective sensor is
defective.
Run the sensor test to verify which sensor detects the paper. Replace the
following corresponding part:
●
Registration sensor (SR8): Replace the registration assembly.
●
Fuser output sensor (SR5): Replace the fuser.
●
Fuser loop sensor 1 or 2 (SR14 and SR15): Replace the fuser.
●
Duplexer re-feed 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 (M13)
drive connector.
Reconnect the connectors of the registration motor (J6), intermediate, and the
DC controller PCA (J131).
The pickup motor (M13) is defective. Execute the pickup-motor driving test in the actuator-drive mode. If the motor is
defective, replace the pickup motor.
The cassette pickup roller is worn or
deformed.
Replace the tray pickup roller.
