What are Ink Supplies?
For each of the four ink colors used in the printer, there are three separate
components. The Printhead and the Printhead Cleaner are supplied together,
and the Ink Cartridge is supplied separately. All of these components are
called Ink Supplies.
Ink Cartridges
The printer's four Ink Cartridges provide yellow, magenta, black, and cyan
ink to the Printheads. The color Ink Cartridges supplied with the printer have
a capacity of 225 cm³, and the black cartridge has a capacity of 400 cm³. It
is also possible to buy and use color cartridges with a capacity of 400 cm³.
All these Ink cartridges are physically the same size, only the
internal capacity varies.
The Ink Cartridges for the hp designjet 4000 series printers require no
maintenance or cleaning. As long as each Ink Cartridge is inserted correctly
into its slot, the ink will flow to the Printheads. Because the Printheads control
the amount of ink transferred to the page, you will continue to see high-
quality printing results even when the ink levels are getting low.
The front panel displays the status of the Ink Cartridge. Using the front panel,
detailed information can be checked on the Ink Cartridges.
