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. Open the access cover.
3. Install a known good black printhead cartridge in the right side
of the carrier and a good color printhead cartridge in the left
side.
4. Close the access cover.
5. Install paper in the sheet feeder.
6. Turn the printer off.
7. Hold down the Paper Feed and Power buttons at the same time
until both lights begin to flash.
8. Release both buttons. Test pages print until the Power button is
pressed.
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
