2 Developer/Paper | Check the voltages on connector CON 1 on | |||
Feed Motor | the developer/paper feed motor board. All | |||
Assembly (M2) | voltages are approximate values: |
| ||
Developer/Paper | Pin # | Voltage | Motor Running | Motor Static |
Feed Motor Cable | 1 | CS | 0 V dc | +5 V dc |
| 2 | ROIR | 0 V dc | 0 V dc |
Engine Board | 3 | GND | 0 V dc | 0 V dc |
4 | +5 V dc | +5 V dc | +5 V dc | |
| 5 | Lo | 0 V dc | +5 V dc |
| 6 | P/S | 0 V dc | +5 V dc |
| 7 | PGND | 0 V dc | 0 V dc |
| 8 | PGND | 0 V dc | 0 V dc |
| 9 | +24 V dc | +24 V dc | +24 V dc |
| 10 | +24 V dc | +24 V dc | +24 V dc |
| If the voltage on pin 4, 9 or 10 are incorrect, | |||
| check continuity of the cable. |
|
•If correct, disconnect CON 1 from the board assembly and check the voltages on the cable connector.
•If incorrect, check continuity of the cable.
•If incorrect, replace the cable.
•If correct, replace the engine board.
•If the voltages on the cable connector are correct, replace the developer/ paper feed motor assembly.
If the voltages on pins 1, 5 and 6 always measure approximately +5 V dc, replace the developer/paper feed motor assembly. If the voltages always measure approximately 0 V dc, check the continuity of the cable.
•If incorrect, replace the cable.
•If correct, replace the engine board assembly.
