Maintenance Station Service Check
The maintenance station has two functions:
•Cleans the printhead nozzles during the print operation.
•Seals the printhead when it is not being used to prevent the nozzles from drying.
| FRU | Action |
|
|
|
1 | Maintenance | As the carrier moves to the right over the |
| Station Assembly | maintenance station, a slot on the bottom of the |
|
| carrier engages a tab on the sled of the |
|
| maintenance station causing the cap to rise and |
|
| seal the printhead. Carrier movement to the left |
|
| uncaps the printhead. The wiper cleans the |
|
| printhead nozzles as the carrier leaves the |
|
| maintenance station. The wiper cleans the |
|
| printhead only when the carrier is moving to the |
|
| left. There should be no wiping action of the |
|
| printhead nozzles when the carrier is moving to |
|
| the right. After the cleaning operation is complete, |
|
| a tab on the maintenance station engages a tab on |
|
| the carrier, causing the wiper to lower. |
|
| Check the maintenance station for worn or broken |
|
| parts. |
|
|
|
2 | Wiper | A worn wiper causes degraded print quality just |
|
| after a maintenance cleaning. Check for a loose or |
|
| worn wiper. |
|
|
|
3 | Cap | A worn cap causes the printhead nozzles to dry |
|
| and clog. Check for a loose or worn cap. |
