Check the Self-Test Report for the following:

The test patterns are even and show a complete grid. If the grids are 
not complete, this might indicate a problem with the nozzles. You might 
need to clean the print cartridges. For more information, see 

The Low Ink warning message value. The value will appear above the 
test pattern for the black, photo (if applicable), or tri-color print 
cartridges. This value represents the number of Low Ink warning 
messages that have displayed for each of the print cartridges. If the 
value displays 1, 2, or 3, the print cartridge might be low on ink. You 
might need to replace the print cartridge. For more information on 
replacing print cartridges, see 

The lines of color extend across the page. 

The color blocks have even consistency. You should see cyan, magenta, 
yellow, violet, green, and red color blocks. If color blocks are missing, 
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 

Also check 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 

 on page 87. Do not clean with alcohol.

Before you replace or clean a print cartridge, you should know the part names 
and how to handle the print cartridge.
