5.4 105, Close Right Cover (Feed Door)
5.4 105, Close Right Cover (Feed Door)
Description: The right cover is also referred to as the feed door. When the
feed door is closed, a magnet on the door actuates the feed door sensor and
signals the DC control board. The sensor is a mechanical switch that is closed
when actuated. Figure 5–5 shows the wiring diagram.
Troubleshooting: Test the operation of the feed-door sensor circuit. Enter
0101 to invoke the 1701 test, as shown in Section 3.1.3. To test the switch
and circuit, open and close the door or pass a magnet close to the sensor. The
contacts close when the magnet is next to the switch. Go to one of the following
steps:
• If a magnet can operate the feed-door sensor circuit, inspect the following:
1. Mechanical operation of the feeding door
2. Mounting and condition of the magnet and sensor assembly
• If the circuit fails to work, do the following:
1. Inspect the 16-pin that connects the DC control board to the wire
harness.
2. Inspect the connection and condition of the 2-pin plug that connects the
feed-door sensor from the wire harness.
3. Swap the feed-door sensor.
4. Swap the DC control board.
5. Swap the LVPSA.
