078-104, 078-901 HCF Feed Out Sensor Fault RAP

BSD-ON: BSD 8.8 HCF Paper Transportation

078-104 Paper fed from the HCF did not actuate the HCF feed out sensor within the specified time.
078-901 The HCF feed out sensor detected paper.

Initial Actions

WARNING: Ensure that the electricity to the machine is switched off while performing tasks that do not need electricity. Refer to GP 10. Disconnect the power cord. Electricity can cause death or injury. Moving parts can cause injury.

• Check the condition of the paper in the HCF. Refer to GP 15 Paper and Media Size Specifications.
• Check for obstructions in the paper path.


Refer to the procedures that follow as necessary:

GP 6 How to Check a Motor.
GP 7 How to Check a Sensor.

1. Enter dC330 code 078-101. Manually actuate the HCF feed out sensor, PL 70.55 Item 25. The display changes. If YES, go to 3. If NO, go to 2.

2. Check the HCF feed out sensor.

3. Enter dC330 code 078-093 to run the HCF takeaway motor. The motor runs. If YES, go to 11. If NO, go to 4.

4. Check the wiring between the HCF takeaway motor (JF57) and the HCF PWB (JF06). The wiring is good. If YES, go to 6. If NO, go to 5.

5. Repair as necessary.

6. Check that the resistance through the HCF takeaway motor is approximately 0.8 ohms between:

• JF57 pin 3 to pins 1 and 2.
• JF57 pin 4 to pins 5 and 6.

The resistances are good. If YES, go to 8. If NO, go to 7.

7. Install a new HCF takeaway motor, PL 70.60 Item 7.

8. Check the voltage between JF06 pins 9 and 10 and ground. +24V is measured. If YES, go to 10. If NO, go to 9

9. Check the +24VDC circuit.

10. Install a new HCF takeaway motor, PL 70.60 Item 7. If the fault persists, install a new HCF PWB, PL 70.60 Item 9.

11. Check the HCF take away components. Install new components as necessary, PL 70.55.
