|
| |
1 | Carrier | Verify the carrier motor connector is connected | |
|
| to the logic board at CN2. If the carrier motor | |
|
| connector is connected properly, check the | |
|
| carrier belt and the ribbon cartridge for wear or | |
|
| damage. Check the belt and pulley | |
|
| engagement. | |
|
| Manually move the carrier the full length of the | |
|
| carriage to check for binds and to be sure the | |
|
| ribbon advances when the carriage moves in | |
|
| either direction. | |
|
| If the carrier binds check the following: | |
|
| • | Correct |

|
| • | Clean and lubricated carrier shaft. |
|
| • | Idler pulley not binding. |
|
| • Ribbon drive rack gear teeth not damaged. | |
|
| If the carrier still binds: | |
|
| Remove the belt and move the carrier again. | |
|
| • | If the bind is gone, replace the carrier motor. |
|
| If the bind remains, replace the carrier. | |
|
| After replacing the logic board or any parts | |
|
| affecting the carrier, perform the bidirectional | |
|
| print adjustment. See “Bidirectional Print | |
|
| Adjustment” on page | |
|
|
| |
2 | Home Position | If the carrier moves manually without binding, | |
| Sensor | but the home position error still occurs, verify | |
|
| that the logic board is receiving +40 V dc on | |
|
| pin | |
|
| position sensor signal is reaching the logic | |
|
| board. | |
|
| Replace the sensor, or the short flexible cable | |
|
| as necessary. | |
