Servicing the Cartridges
Service Station
The service station is based on that of the DesignJet 650C, with some differences.
D The service station is easier to access and remove, and is replaceable as one unit.
D The absence of a drop detector implies a different cartridgeĆmaintenance algorithm to
guarantee correct nozzle conditions. The plotter warms the nozzles and spits ink:
- Before each plot.
- After each cartridge change.
- While printing, depending on: cartridge, humidity, temperature, and plot ink density.
D The ventilation holes, which were located on the serviceĆstation sled on the DesignJet
650C, are now located on the ink separator to prevent them from becoming clogged.
Spittoon
A single, redesigned spittoon is located on the right side of the plotter.
Primer
The plotters feature a manual primer, based on that of the DeskJet 1200, instead of the
automatic one of the DesignJet 650C. (See ' User's Guide, w Cleaning the cartridge nozzles.)
D A bellows assembly provides a vacuum to suck ink from the nozzles. The suction tubes
have a wider diameter than those of the DesignJet 650C, to help prevent clogging.
D An ink separator isolates the bellows from the cartridges, preventing ink contamination
of the bellows.
Although the primers for the DesignJet 230/250C and DesignJet 330/350C look identical,
their characteristics are different. Installing the incorrect primer can damage the cartridges
or reduce the servicing of the cartridges. For the correct part numbers for the primers '
