FRU 1 ADF 2 Interval sensor 3 Interval sensor cable (interval sensor to CN10 on the MDC card) 4 Motor driver card Action Check for any signs of paper or other debris that might be present in the ADF assembly over the interval sensor. If nothing found, go to step 2. Enter the Diagnostic Menu (turn on MFP while holding 3 and 6), select SCANNER TESTS and then select Sensor Tests. Check the interval sensor for correct operation. Note: You can check the interval sensor by putting a sheet of paper over the sensor. This is easier to perform by first removing the pick arm assembly. If the sensor fails the test, go to step 3. Check to make sure the interval sensor cable is correctly installed at the sensor and atCN10 on the motor driver card. If the cable is not installed correctly, reinstall the cable. If installed correctly, go to step 4. Turn the power off and disconnect CN10 on the motor driver card. Measure the voltages at the board: Interval sensor-reflective type (normally closed) Connector CN10 (motor driver card) CN10-Pin 7 0 V dc CN10-Pin 8 +5.0 V dc CN10-Pin 9 +5.0 V dc Note: All voltages are approximate values. If incorrect, replace the motor driver card. If correct go to step 5. 2-96 Service Manual
