Performing a Nozzle Drop-out Test

Before starting printing, check whether binder is discharged correctly from the print heads.

The nozzle drop-out test outputs thin, narrow, band-shaped print data to check whether these bands are broken. Printing is actually performed, so level the surface of the fixture material before the test.

Procedure
  1. Level the surface of the fixture material if you have not yet done so.

  2. Click icon_ctrl_open.

    The window for importing the file is displayed.

  3. Specify the following file on the desktop to load it as the data for the nozzle drop-out test.
    • PB-600: testprint_PB-600.alf
    • PB-400: testprint_PB-400.alf
  4. Click icon_ctrl_print.

    A confirmation message appears. Click OK.

    Printing for the nozzle drop-out test starts. The printing time is approximately 4 minutes.
  5. After the job is printed, leave it alone for 20 minutes.
  6. Check the test result.
    If there are horizontal lines in the printed bands, binder is not being discharged from at least one nozzle, so clean the print heads. If horizontal lines are difficult to detect, try slowly lifting the part that is in question. If you can lift the band without it breaking, there are no horizontal lines. If there are horizontal lines, the band will break, preventing you from lifting it.
