291.02 Error code service check
Second ADF scan sensor (A) jam.
Note: Before starting this service check, make sure the sensor cable is correctly installed.
FRU Action
1 ADF The second scan sensor has detected the leading edge of the sheet
but did not detect the training edge. The first scan sensor detected
the leading edge. Enter the Diagnostics Menu (turn on MFP while
holding 3 and 6), select SCANNER TESTS, and select Feed Tests.
Load several sheets through the ADF to check for any jams prior to
the second scan sensor. If the jam is persistent, go to Step 2.

ADF feed gears and
hardware
Check the ADF feed gears, pulleys, and hardware for any signs of
binding, broken, or damaged parts. If any problems are found,
replace the complete ADF assembly. See “ADF complete assembly
removal” on page 4-15.
Note: Whenever the complete ADF assembly is replaced, it is
necessary to perform scanner registration. See “Scanner
registration” on page 4-4.
Note: To help isolate a problem with the ADF feed system you can
run the Feed Test from the SCANNER TESTS in the Diagnostics
Menu. Put several sheets of media in the ADF tray, and observe the
gears, motor, belts, and other hardware for any signs of a malfunction
that might cause the media not to reach the second scan sensor.

Second scan sensor cable
(second scan sensor to
CN9 on the MDC card)
Check to make sure the second scan sensor cable is correctly
installed at the sensor at CN9 on the MDC (motor driver card in the
ADF). If the cable is not installed correctly, reinstall the cable. If
installed correctly, go to step 4.
