Maintaining ink cartridges and printheads
The ink cartridges should not require maintenance except for replacing them when the ink 
runs out. The printheads require very little maintenance. 
Replacing ink cartridges
CAUTIONThe ink in HP ink cartridges has been formulated to ensure superior print quality and 
compatibility with your printer. Damage to the printer that results from modifying or refilling the 
ink cartridges, or from using non-HP ink cartridges, is not covered under the warranty.
You do not have to replace all four ink cartridges when one runs out. Only replace the ink 
cartridge for the color that is low or out.
You can check the ink levels from the Toolbox. You can also check the printer control panel to 
see if an ink cartridge is low, as shown here. 
The ink cartridge is low on ink when the Ink 
Cartridge light blinks, and one or more of the 
color indicator lights is on.
You can press the   (resume button) to 
continue printing.
The ink cartridge is out of ink when the Ink 
Cartridge light, one or more of the color indicator 
lights, and the Resume light are on. 
You must replace the ink cartridge to continue 
printing.

Checking the printheads
If the Toolbox is installed on a computer running Windows, you can check the health of the 
printheads. Replace the printheads when print quality degrades. You can also check the 
quality by printing a printer configuration page. See “Printing a configuration page”.
To check the printheads from the Toolbox
1Open the Toolbox.
2On the Information tab, click Printhead Health. 
3Check the status of each of the printheads. 
4If the status of one or more printheads is listed as Bad, replace the printhead. See 
“Replacing the printheads”.
To check the printheads using a printer configuration page
Print a printer configuration page by holding down the   (power button) and pressing the   
(cancel button) on the printer once. Release the   (power button). 
Cleaning the printheads
CAUTIONHP is not responsible for damage to the printer that results from modifying 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.
Clean the printheads from the Toolbox (Windows) or the HP Inkjet Utility (Mac OS). Or, follow 
the procedures below for cleaning the printheads from the control panel.
There are three cleaning levels available. Run the level 1 cleaning. Only run the level 2 
cleaning if the results of the first cleaning were unsatisfactory. Similarly, only run the level 3 
cleaning if the results of the second cleaning were unsatisfactory.
NoteOnly clean the printheads when necessary; cleaning the printheads uses ink and shortens the 
life of the printheads.
To clean the printheads from the Toolbox
1Open the Toolbox.
2Click the Printer Services tab.
3Click Clean Printheads and follow the instructions on the screen.
To clean the printheads from the HP Inkjet Utility
1Open the HP Inkjet Utility.
2Click Clean and follow the instructions on the screen.

Aligning the printheads

printheads are misaligned, you can align them from the control panel, from the Toolbox 
(Windows), or from the HP Inkjet Utility.
