Troubleshooting and parts
1. Make sure that there are no residual pieces of paper are in the paper path that could cause the
paper to jam in this area.
2. Make sure that the media meets specification in both type and size for duplexing. Minimum paper
size is 210 x 280 mm (8.27 x 11 inches)to 216 x 356 mm (8.5 x 14 inches).
3. Perform a paper sensor test and confirm correct operation of all sensors. In particular, check the
Duplexer Paper Sensor in the following manner:
a. At the start of the Paper Sensor Test, the duplexer sensor (third digit of the four in the upper
left of the display) should be “0” (at the start of the test, all four digits should be “0”.)
b. Remove the cassette and release the duplexer pan, when in the pan is in its full down
position, the duplexer sensor digit should be “1”.
c. If the sensor flag is manually moved, it the digit should show a “1” when the flag is in the full
down position, a “0’ as the flag moves to the middle position and a “1” when the flag is in
the full up position.
d. If the sensor does not respond as described above, replace the HVPS assembly
(RM1-6280-000CN).
e. If the sensor is working properly, the error only happens on a duplex job, and the media is
jammed in the rear door or in the fuser with only one side printed, replace the pendulum
assembly (RM1-6598-000CN).
f. If the error persists, replace the lower paper feed guide (P/N RM1-6263-000CN).
