HP recommends that you replace the empty cartridge with a new HP cartridge. See Order ink supplies
on page 79, Remove an ink cartridge on page 59, and Insert an ink cartridge on page 61.
The use of refilled or non-HP ink cartridges 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.
To force the printer to accept cartridges that it believes to be empty, follow these instructions:
1. Install the cartridge in the printer (see
Insert an ink cartridge on page 61).
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.
4. Highlight Replace ink cartridges, but do not select it.
5. Press the Cancel key and the Up key at the same time, and hold them down for at least two seconds.
6. The front panel displays 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 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
prints 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.
To maintain optimum print quality, the printheads are automatically tested at regular intervals, and
automatically serviced when necessary. This takes a little time and can occasionally delay printing.
When a printhead eventually needs to be replaced, the front panel will display a message.
