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 (i.e. prevent the use of the print heads that are causing discharge issues). 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.

Procedure
  1. Set up the media.
  2. Tap Panel_Icon_Menu.
  3. Tap Cleaning - Printing Test.
  4. Select Nozzle Mask Test and tap Execute.
    Printing of the test pattern starts.
  5. Check for the nozzle group with dot drop-out or dot displacement by viewing the results of the printing test.
    "1" or "2" is the nozzle group. The following shows a dot drop-out in nozzle group 2.

    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.

  6. If you have opened the front cover, close it.
  7. Tap Panel_Icon_Home to return to the home screen.

2. Limit the print heads used for printing.

Use VersaWorks to select the nozzle group used for printing. For the detailed procedure, see the VersaWorks Master Guide.
