(260-2979)              Print Nozzle Test             Faxback Doc. # 19096

The print cartridge nozzle test help you pinpoint any clogged nozzles.  The
nozzle test also cleans the print cartridge by clearing (purging) the
nozzles.  A test line prints so you can see if the cleaning (purging)
process was successful.  Use the nozzle test:

    When you suspect the nozzles are clogged.
    When characters are not printing completely

To run the nozzle test:

1.  Load paper in the sheet feeder.

2.  Open the WinWriter 150c Printer Control dialog box.

3.  Choose the Cartridges tab.

4.  Choose the Clean Print Nozzles button.

    The printer feeds a sheet of paper and prints the nozzle test pattern.

5.  Examine the test pattern.

6.  Compare the diagonal line at the top and bottom of the test pattern.

    Look for a break in the diagonal line.  A broken line shows any clogged
    nozzles.

    If the bottom line shows improvement, rerun this test.  If improvement
    continues, rerun the test again.  If all nozzles are not printing after
    running the test three times, continue with the next step.

7.  If print quality does not improve, remove and reinstall the print
    cartridge.  See "Replace Print Cartridges," Faxback Doc. 19099 for
    complete instructions on removing and reinstalling a print cartridge.

8.  Repeat the nozzle test.

9.  If the line is still broken, clean the nozzles and contacts.  See
    "Cleaning Nozzles and Contacts," Faxback Doc. 19093.
