Cause Solution
Poor contact of the duplex reverse-motor
connector
Reconnect the connectors (J202 and J201) on the high-voltage power supply
(upper) PCA and connector (J113) on the DC controller PCA.
The duplex reverse motor is defective Replace the duplex drive assembly. See Duplex-drive assembly
on page 308.
Poor contact of the duplexing reverse-motor
connector
Reconnect the connectors of the duplexing reverse motor (J20) and the
duplexing driver PCA (J202).
The duplexing reverse motor is defective Replace the right door assembly. See Right-door assembly on page 194.
Table 7-22 Causes and solutions for duplex repick jams
Cause Solution
The duplex re-pickup sensor lever is set
incorrectly or damaged
Check the sensor lever to make sure it is set correctly. If it is damaged, replace
the right door assembly. See
Right-door assembly on page 194.
The spring of the duplex re-pickup sensor
lever is unhooked
Check the spring and place it in correct position.
Poor contact of the duplex re-pickup sensor
connector
Reconnect the intermediate connector (J90) and connector (J107) on the DC
controller PCA.
The duplex re-pickup sensor is defective Run the sensor test in the sensor monitor mode to verify that the duplex re-
pickup sensor is functioning properly. If it is not, replace the right door
assembly. See
Right-door assembly on page 194.
The spring of the duplex-repick-sensor lever is
unhooked
Check the spring and place it in the correct position.
The duplex-repick-sensor lever is damaged Replace the duplex repick sensor.
Poor contact of the duplex-repick-sensor
connector
Reconnect the intermediate connector (J90) and connector (J107) on the DC
controller PCA. If the problem persist, replace duplex repick sensor.
The duplex-repick sensor is defective Check the duplexing media-repickup sensor by the sensor monitor mode. If the
sensor is defective, replace the duplexing repick sensor.
Poor contact of the duplex reverse connector Reconnect the connectors of the duplex repick motor (J20), intermediate (J202
and J201) and the duplex driver PCA (J113).
The duplex-repick motor is defective Replace the duplex drive assembly. See Duplex-drive assembly
on page 308.
Table 7-23 Causes and solutions for residual media jams
Cause Solution
Poor contact of the loop-sensor connector and
loop sensor 1 and 2
Reconnect the connectors of the loop 1 sensor (1 and 2):
●
Loop 1 (J11, J352, J350, J50) and the DC controller (J139)
●
Loop 2 (J10, J352, J350, J50) and the DC controller (J139)
The loop sensor is defective Check the loop sensor via the sensor monitor mode. If the sensor is defective,
replace 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 and place it in the correct position.
