Maintenance Station Service Check
The maintenance station has three functions:
1. Wipes the printhead nozzles to clear them of dirt.
2. Provides a place for the printheads to spit all nozzles keeping
them clear prior to printing.
3. Seals the printheads when not in use to prevent the nozzles
from drying.

Action
As the carrier moves to the right over the
maintenance station, a tab on the bottom of the
carrier engages a tab on the sled of the
maintenance station causing the caps to rise and
seal the printhead. Carrier movement to the left
uncaps 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 printheads are wiped, a tab on
the carrier engages a tab on the maintenance
station and wipers are lowered. The carrier will
then move to the right over the felt pad where they
will spit all nozzles.
Check the maintenance station for worn or broken
parts.
Worn wipers cause degraded print quality just after
a printhead maintenance cleaning. Check for loose
or worn wipers.
Worn caps cause the printhead nozzles to dry and
clog. Check for loose or worn caps.
