HP Designjet 4500 Printer series - Manual (Page 319)

You are recommended to replace the empty cartridge with a new HP cartridge: see Remove an ink
cartridge and Insert an ink cartridge.
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).
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 will display a series of warning messages. In response to each message, press
the Cancel key to cancel the process, or the Select key to confirm that you wish to continue.
When you have pressed Select 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
In order to increase printing speed, two printheads are connected to each ink cartridge, giving eight
printheads in total.
The printheads are extremely durable and do not need to be replaced every time an ink cartridge is
replaced. They will continue giving excellent results even if the ink cartridges are low in ink.
