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 color blocks have even consistency and are representative of the
colors listed below.
You should see cyan, magenta, and yellow color blocks.
6. Check the color blocks and lines of color for streaking or white lines.
Streaks might indicate clogged nozzles or dirty contacts. You might need to clean
the print cartridges. For more information on cleaning the print cartridges, see
Clean the print cartridges. Do not clean with alcohol.
If color blocks are missing, or if a block of color is muddy or does not match the
label indicated below the block, this might indicate that the tri-color print cartridge
is out of ink. You might need to replace the print cartridge. For more information
on replacing print cartridges, see Replace the print cartridges.
Work with print cartridges
To ensure the best print quality from your HP All-in-One, you will need to perform
some simple maintenance procedures. This section provides guidelines for handling
the print cartridges and instructions for replacing, aligning, and cleaning the print
cartridges.
You might also need to check your print cartridges if the Check Print Cartridge light
is on. This might mean that the print cartridges are not installed properly or are
missing, the plastic tape has not been removed from the print cartridges, the print
cartridges are out of ink, or the print carriage is blocked.
For more information on troubleshooting problems with your print cartridges, see the
onscreen HP Image Zone Help that came with your software.
