2 Wiper A worn wiper causes degraded print quality just

3 Cap A worn cap causes the printhead nozzles to dry

As the carrier moves to the right over the
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. Car rier movement to the le ft

printhead nozzl es as the carrier leav es 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 lo wer.
