When to Replace
When to change your HP No. 81/HP No. 83 supplies is mostly determined by you with guidance from the front
panel. In conjunction with the messages displayed in the front panel and the message explanations in
Message
Descriptions , you will be able to choose for yourself when is the right time (for your particular case) to change
the HP No. 81/HP No. 83 supplies.
The front panel will also display the ink level and will tell you when your ink supply is low, very low or empty.
This means you have constantly updated information about your HP No. 81/HP No. 83 supplies.
Printhead life is warranted to 700ml of ink consumed. However, on average the anticipated life expectancy of
the printheads is two or three times this. This is provided that the printhead is used under normal operating
conditions (using HP ink cartridges only) and its “install before date” has not lapsed. However results vary
depending on the print mode setting you use.
When you replace the printhead always replace the corresponding printhead cleaner.
