Second scan sensor—
electrical checks
Turn the power off, and reconnect CN9 to the motor driver card.
Measure the voltages in the table below with the sensor in normal
operation (sensor closed) and with the sensor open (sensor flag
activated).
If the voltages are incorrect, replace the second scan sensor. If this
does not fix the problem, 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.
FRU Action
1 ADF The leading edge of the media was detected by the first scan sensor,
but never detected by the trailing edge.
Clear any media that may be in the ADF. Enter Diagnostics Menu
(turn on MFP while holding 3 and 6), select SCANNER TESTS, load
some sheets of paper in the ADF paper tray, and select Feed Tests.
If the error continues at or near the same point, go to step 2.

Area around the first scan
sensor
Check the area around the first scan sensor for anything that might
cause the stop or jam prior to exiting the first scan sensor. If the
problem continues and you cannot find anything causing this jam,
replace the complete ADF assembly.
Note: Whenever the complete ADF assembly is replaced, it is
necessary to perform scanner registration. See “Scanner
registration” on page 4-4.
