Partially Restricting the Print Heads Used for Printing
When dot drop-out or dot displacement is not improved even after renewing the ink, partially restrict the
print heads to use for printing. This operation is called the "nozzle mask," and while it slows down printing
speed, it also allows you to decrease the impact of dot drop-out or dot displacement.
First print a test pattern, and then select the nozzle group to use by viewing the test results. After that,
use VersaWorks to select the nozzle group used for printing.
1. Perform a printing test for the nozzle mask.

Check for the nozzle group with dot drop-out or dot displacement by viewing the results of the printing
test.
The results of the printing test are displayed separately for nozzle groups "1," "2," and "3." The fol-
lowing shows dot drop-outs in nozzle groups "1" and "3."
If the printing-test results are difficult to interpret
Check the results in a bright location, changing your line of vision. They are visible using the reflection of the
light.
