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.
