User's Manual

If an icon shows a hollow ink drop, the print cartridge represented by that color icon
has very little ink remaining and will need to be changed soon. Replace the print
cartridge when the print quality starts to degrade.
For more information on the ink level icons on the color graphics display, see Color
graphics display icons.
You can also check the estimated amount of ink remaining in your print cartridges from
the computer. If you have a USB connection between your computer and the HP all-in-
one, see the onscreen HP Image Zone Help for information on checking the ink levels
from the Printer Toolbox. If you have a network connection, you can check the ink
levels from the Embedded Web Server (EWS). See the Network Guide for information
on accessing the EWS.
Print a self-test report
If you are experiencing problems with printing, print a self-test report before you replace
the print cartridges. This report provides useful information on several aspects of your
device, including your print cartridges.
1 Load letter, A4, or legal unused plain white paper into the input tray.
2 Press Setup.
3 Press 2, then press 5.
This displays the Print Report menu and then selects Self-Test Report.
The HP all-in-one prints a self-test report, which might indicate the source of the
printing problem. A sample of the ink test area of the report is shown below.
4 Make sure the test patterns are even and show a complete grid.
If more than a few lines in a pattern are broken, this might indicate a problem with
the nozzles. You might need to clean the print cartridges. For more information, see
Clean the print cartridges.
5 Make sure the lines of color extend across the page.
If the black line is missing, faded, streaked, or shows lines, this might indicate a
problem with the black or photo print cartridge in the right slot.
