Elevator Assembly; Axis Assembly; Electronics Module - HP DesignJet 2500CP Service Manual

Elevator Assembly

The Elevator Assembly is located under the Refill Assembly. Its function is to
raise and lower the four ink cartridges. The Elevator Assembly is raised and
lowered by three cams and a stepper motor.
When the Elevator is in the up position it causes negative air pressure in
D
the Refill Assembly. This has the effect of drawing ink from the ink
cartridges into the printheads.
When the Elevator is in the down position the air pressure is stabilized.
D
The middle position enables the removal and installation of the four ink
D
cartridges.
X Axis Assembly

a dc motor. This turns the drive roller via a worm drive and a helical gear.
