Roland TrueVIS VG2-540 - Partially Restricting the Print Heads Used for Printing

Parally Restricng the Print Heads Used for Prinng
When dot drop-out or dot displacement is not improved even if super cleaning is performed, parally restrict the
print heads to use for prinng (i.e. prevent the use of the print heads that are causing discharge issues). This
operaon is called the "nozzle mask," and while it slows down prinng speed, it also allows you to decrease the
impact of dot drop-out or dot displacement.
First print a test paern, and then select the nozzle group to use by viewing the test results. Aer that, use Versa-
Works to select the nozzle group used for prinng.
1. Perform a prinng test for the nozzle mask.
Procedure
1. Load the media.

4. Press [ENTER].
Prinng of the test paern starts.
5. Check for the nozzle group with dot drop-out or dot displacement by viewing the results of the prinng test.
"1" or "2" is the nozzle group. The following shows a dot drop-out in nozzle group 2.
