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 caps to rise and

 

 

seal the printheads. Carrier movement to the left

 

 

will uncap the printheads. The wipers clean the

 

 

printhead nozzles as the carrier leaves the

 

 

maintenance station. The wipers clean the

 

 

printheads 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 wipers 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 loose or

 

 

worn wiper.

 

 

 

3

Cap

A worn cap causes the printhead nozzles to dry

 

 

and clog. Check for loose or worn cap.
