291.00 Error code service check
Static jam—second scan sensor (A).
Note: Before starting this service check, make sure the second scan sensor cable is correctly installed.
FRU Action
1 ADF The media is jammed or stuck in the ADF at the second scan sensor.
Check for any signs of paper or other debris that might be present or
jammed in the ADF assembly around the second scan sensor.
2
Second scan sensor Enter the Diagnostics Menu (turn on MFP while holding 3 and 6),
select SCANNER TESTS, and select Sensor Tests. Check the
second scan sensor for correct operation.
Note: To manually activate the sensor, you can either open the jam
removal tray (it is necessary to defeat the jam tray sensor by placing
a piece of paper in the sensor to turn off the jam tray message on the
display), or you can manually feed a piece of paper through the ADF.
If the sensor fails the test, go to step 3.

Second scan sensor cable
(second scan sensor to
CN9 on the MDC card)
Check to make sure the first scan cable is correctly installed at the
sensor CN9 on the SCC (scanner control card in the ADF). If the
cable is not installed correctly, reinstall the cable. If installed correctly,
go to step 4.
4
Motor driver card Turn the power off, and disconnect CN9 on the motor driver card.
Measure the voltages in the table below:
If incorrect, replace the motor driver card. If correct, go to step 5.
