ADF exit jam sensor (A) off.
Note: Before starting this service check, make sure the sensor cable is installed correctly.
FRU Action
1 ADF—jammed media Check for any signs of media or other debris that might be present in
the ADF assembly around the exit sensor flag. Remove any media or
debris. If nothing is found, go to step 2.

ADF exit sensor flag Check the exit sensor flag to make sure it operates freely and does
not hang or bind. If the flag does not operate correctly and cannot be
made to operate correctly, 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.
If the flag operates correctly, go to step 3.

ADF exit sensor Enter the Diagnostics Menu (turn on MFP while holding 3 and 6),
select SCANNER TESTS, and select Sensor Tests. Check the ADF
exit sensor for correct operation.
Note: You can check the ADF exit sensor by moving the exit sensor
flag or by manually feeding a sheet of paper through the ADF.
If the sensor fails the test, go to step 4.
