Maintenance Station Service Check

The maintenance station has two functions:

•Cleans the printhead nozzles during the print operation.

•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.
2	Wiper	A worn wiper causes degraded print quality just
		after a maintenance cleaning. Check for a loose or
		worn wiper.
3	Cap	A worn cap causes the printhead nozzles to dry
		and clog. Check for a loose or worn cap.
