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.

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 4-17.

 

 

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.
