Theory of Operation
Note
When servicing a printer, it’s recommended that you replace and clean
the wiper. Be careful not to scratch it when you install it.
Maintenance station cam
A special cam on the end of the drum has two tracks used to control the locking
of the waste bin and positioning of the maintenance station. The left-side raised
track is used to control the waste bin lock. When the drum is rotated
counterclockwise more than one revolution, the waste bin lever is forced out of
the center of the track which lifts the lever and unlocks the waste bin. Rotating
the drum clockwise locks the waste bin drawer. The right-side track is used by
the maintenance station’s cam pin to position the maintenance station against or
away from the printhead, as well as operate the air valve.
