Lexmark 3200 User Manual page 47

The printer feeds a sheet of paper and prints a nozzle test pattern,
similar to the one shown:
2
Examine the test pattern.
The example above shows a test pattern of all nozzles functioning
correctly.
3
Compare the diagonal line above the printed bars to the diagonal
line below the printed bars.
Look for a break in the diagonal lines. A broken line indicates
clogged nozzles.
If the bottom line has fewer breaks, or better print quality than the
top line, run the test two more times. If the print quality is
satisfactory after running the test three times, the print nozzles are
clean. You do not need to complete the remaining steps.
If the print quality of both lines is not satisfactory after running the
test three times, go to step 4.
4
Remove and reinstall the print cartridge.
5
Repeat the nozzle test.
6
If the lines are still broken, wipe the print cartridge nozzles. For
help, see "Wiping print nozzles and contacts" on page 44.
