Paper feed pick assembly does not feed, paper feed pick motor does not turn
Note: A noisy or chattering motor or a motor that fails to turn can be caused by:
| • | A defective motor | |
| • A bind in the paper feed mechanism | ||
| • | Defective gears |
|
| • | Defective engine board | |
| • | Defective power supply | |

1 | Power Supply | Check the power supply. See the “Power Supply | |
|
|
| Service Check” on page |
|
|
| voltage is incorrect, replace the power supply. |
|
|
| |
2 | Engine Board | Disconnect (J6) from the engine board. With the | |
|
|
| power on, check the voltage between pins 6, 10, |
|
|
| and ground. The voltage at pin 6 should be |
|
|
| approximately +35 V dc. The voltage at pin 10 |
|
|
| should be approximately +5 V dc. If either of these |
|
|
| readings are incorrect, replace the engine board. |
|
|
| Check continuity between (J2) on the RIP card |
|
|
| and (J14) on the engine board. If correct, replace |
|
|
| the engine board. If incorrect, go to step 3. |
|
|
| |
3 | Paper Feed Pick | Disconnect (J6). Check between 6 and 7 on the | |
| Motor | connector for approximately 27.8 ohms. If reading | |
|
|
| is incorrect, replace the paper feed pick motor |
|
|
| assembly. If reading is correct, check the |
|
|
| continuity between each 6 and 7 to the motor |
|
|
| case. If continuity exists, replace the paper feed |
|
|
| pick motor assembly. |
| Index Motor | Check the index motor connector J16 pin 2 to | |
| ground for approximately 27 volts. If voltage is | ||
|
|
| incorrect, replace the system board. If reading is |
|
|
| correct, check the continuity. See “Index Motor |
|
|
| Service Check” on page |
|
|
| remains, go to step 4. |
|
|
| Note: If a short exists in the paper feed motor, |
|
|
| damage to the engine board drivers and power |
|
|
| supply may occur. |
