HP recommends that you replace the empty cartridge with a new HP cartridge. See Order ink supplies
on page 67, Remove an ink cartridge on page 48, and Insert an ink cartridge on page 50.
Although it is possible to use refilled or non-HP ink cartridges, either choice has several serious
disadvantages:
There is some risk of damaging the printer. In this case the printer warranty will not be valid for
any printer repairs that are related to the cartridge, nor for any problems due to ink
contamination.
You will invalidate the warranty of all printheads of the same color used in the printer
subsequently, unless and until the whole ink system (including ink tubes) is replaced.
Print quality may be impaired.
The printer will be unable to estimate the ink level in the cartridge, and will report it as empty.
If you decide to use refilled or non-HP ink cartridges, you will need to follow these instructions to make
the printer use a cartridge that it believes to be empty.
1.
Install the cartridge in the printer (see
Insert an ink cartridge on page 50).
2.
The front panel will complain that the cartridge is empty, and the cartridge removal process will
start. Press the Cancel key to stop this automatic process.
3.
At the front panel, select the
icon; highlight Replace ink cartridges, but do not select it.
4.
Press the Cancel key and the Up key at the same time, and hold them down for at least two
seconds.
5.
The front panel will display a series of warning messages. In response to each message, press the
Cancel key to cancel the process, or the OK key to confirm that you wish to continue.
When you have pressed OK in response to all warning messages, the front panel will give the usual ink
cartridge status display, but the refilled or non-HP cartridge will be shown as empty with a warning
sign.
Printheads
The printheads are connected to the ink cartridges. They use jet action to put ink on the paper. Each
printhead has two ink-cartridge connection points and two sets of nozzles, which means that each
printhead can print in two different colors. For example, the printhead below prints in magenta and
yellow.
The printheads are extremely durable and do not need to be replaced every time an ink cartridge is
replaced. They provide excellent results even when the ink cartridges contain a low level of ink.
