Caring for your print cartridges
Cleaning the print nozzles
The print cartridge nozzle test helps you pinpoint any
clogged nozzles. The nozzle test also cleans the print
cartridge by cleaning (purging) the nozzles. A test line
prints so you can see if the cleaning 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
Make sure there is paper in the automatic feeder.
2
From the printer’s Control Program, click the
Cartridges Tab .
For help opening the Control Program, see
“Opening the Control Program” on page 8.
3
Click the Clean Print Nozzles button.
The printer feeds a sheet of paper and prints a
nozzle test pattern, similar to the one shown below.
4
Examine the test pattern.
The example above shows a test pattern of all
nozzles functioning correctly.
5
Compare the diagonal line above the printed bars
to the diagonal line below the printed bars.
