3Check 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 clean the print cartridges on page 87.

–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 replace the print cartridges on page 83.

–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 replace the print cartridges on page 83. Also check for streaking or white lines. Streaks might indicate clogged nozzles or dirty contacts.
