ADF exit 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 the sensor open (sensor flag
activated).
If the voltages are incorrect, replace the ADF exit 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.
