Ink Cartridges
Each ink cartridge contains 30 grams of liquid ink, and is rated for as
much as 700 pages of text.
Each color cartridge is physically coded to fit in its own color slot.
Also, the ink cartridge has an electronic label which is sensed by the
cartridge sensor. The ink is nontoxic, but contains isopropyl alcohol
and should not be swallowed or gotten in the eyes. It will perma-
nently stain clothing.
To prevent ink leaks, always ship the printer with the ink cartridges
installed, and with the carriage locked in place.
Also make sure the four printheads are capped before switching the
printer off. A star (*) is displayed when the heads are automatically
capped.
