292.00 Error code service check
ADF cover open jam.
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.
5
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
operations (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.
