Maintaining the printheads
The printheads require very little maintenance. You can print up to
16,000 black and white pages and 24,000 color pages before you need
to replace a printhead. When a printhead needs to be replaced, the
LCD displays an alert message.
Cleaning the printheads
If the printed characters are incomplete, or if dots or lines are missing
from the printouts, you might need to clean the printheads. This is a
symptom of clogged ink nozzles, which are a result of prolonged
exposure to air.
If you have the Toolbox installed, you can clean the printheads from the
Toolbox. Open the Toolbox, click the Printer Services tab, and then
click Clean Printheads. If you do not have the Toolbox installed, or if
you use an Apple computer with a Macintosh operating system, follow
the procedure below for cleaning the printheads from the LCD panel.
There are three cleaning levels available. Level 1 cleaning is the
quickest and uses the least amount of ink. You should run the level 2
cleaning only if the level 1 cleaning was insufficient. The level 3
cleaning is the most thorough and consumes the most ink and time.
After each cleaning, the printer prints a test page so that you can check
the print quality.
To perform a level 1 printhead cleaning
1 Press and hold down the POWER button.
2 While holding down the POWER button, press the CANCEL button
twice.
3 Release the POWER button. The printer begins the printhead
cleaning process.
To perform a level 2 printhead cleaning
1 Press and hold down the POWER button.
2 While holding down the POWER button, press the CANCEL button
twice and then press the RESUME button once.
HP is not responsible for damage to the printer that results from
modifying the printheads.
Do not clean the printheads unless necessary; cleaning the printheads
wastes ink and shortens the life of the printheads.
