What are the Supplies?
For each of the six ink colors used in the printer, there
are three separate components. The printhead and the
printhead cleaner are supplied together, the ink
cartridge is supplied separately. Two types of ink
supplies are available, dye based ink and pigment-
based UV ink. The components of the normal dye
based ink are called the HP No. 81 Supplies and the
components of the pigment-based UV ink are called
the
. The ink supplies are
coded with an HP No. 81/HP No. 83 selection number
to help you reorder the correct replacement supplies.
They also each have a distinctive icon to aid
identification. See
Ink Cartridges
The ink cartridges for your printer 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 notifies you when an ink
cartridge’s ink level is low. You can also
check the ink levels of all the ink cartridges to
determine if an ink cartridge needs to be
replaced, see
. If the ink
cartridge is empty, the printer stops printing. See
Printheads
The printheads are extremely durable and do not need
to be replaced every time an ink cartridge is replaced.
They are independent of the ink cartridges and will
continue giving excellent image quality results even if
the ink cartridges are low in ink. See
If you notice a decline in print quality, refer to
located in the “Solutions” tab.
Printhead Cleaners
The printhead cleaners keep the printheads in good
condition and they prevent them from being damaged
when the printer is not active. They service the
printhead, making sure it is always ready to be used
and prevent them from drying out when not in use.
Printhead cleaners come with the printheads when you
purchase them. When you replace a
printhead always replace the printhead
cleaner. Leaving the old printhead cleaner in
the printer will shorten the new printhead’s
life and possibly damage the printer.
