HP Designjet 4500 Printer series - Manual (Page 318)

Ink cartridges
The printer's four ink cartridges provide yellow, magenta, black, and cyan ink to the printheads. The
color 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 and
black cartridges with a capacity of 775 cm³.
NOTE The 225 cm³ and 400 cm³ cartridges are physically the same size: only the internal
capacity varies. The 775 cm³ black cartridge is longer.
Ink cartridges 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.
Replacing ink cartridges
You can highlight the icon at any time to check the ink levels of all the ink cartridges (as illustrated
below).
The front panel warns you when a cartridge's ink level is low. When a cartridge is empty, the printer
stops printing and the front panel explains why:
