Maintenance Station Service Check
The maintenance station has three functions:
1.Wipes the printhead nozzles to clean them of dirt.
2.Provides a place for printheads to fire all nozzles, keeping them clear prior to printing.
3.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. Replace if needed. Go to the “Maintenance |
|
| Station Removal” on page |
|
| Worn wipers cause degraded print quality just after |
|
| a maintenance cleaning. Check for loose or worn |
|
| wipers. |
|
| Worn caps cause the printhead nozzles to dry and |
|
| clog. Check for loose or worn caps. |
