To run a complete test page of black and color patterns, be sure the
printhead cartridges are in good condition.
To enter the test:

carrier and a good color cartridge in the right.
4. Close the scanner unit.

The printer prints four lines of black and color printhead cartridge
nozzle purge patterns followed by a black and color nozzle test
pattern. The purge pattern is used to clear all printhead nozzles. The
nozzle test pattern prints all nozzles on a diagonal line. There should
be no breaks in the nozzle test pattern. A break in the pattern
indicates one or more nozzles are not working.
If a print quality problem exists, see
