This test prints the test page.
To run a complete test page of black and color patterns, be sure the
printhead cartridges are in good condition.
To enter the test:
1. Turn the printer on.
2. Lift the scanner unit.
3. Install a known good black print cartridge in the left side of the
carrier and a good color cartridge in the right.
4. Close the scanner unit.
5. Load paper in the paper support.
6. Press the Options button until “Maintenance” appears.
7. Press the right arrow to self test.
8. Press the Select button and the test runs.
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 “Print Quality service check”
