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.

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. Do not wipe 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.  |
