Step 1: Performing a Nozzle Drop-out Test

Before you carry out actual printing, perform a printing test to ensure no dot drop-out or dot displacement occurs. If dot drop-out or dot displacement occurs, perform cleaning of the print heads (normal cleaning).
MEMO

When performing printing tests successively, you can select Vertical Printing or Horizontal Printing as the printing position for the second and later tests in comparison to the first test.

  2. Click Output.

    Printing of the test pattern starts.

  3. Check whether there is dot drop-out or dot displacement in the test pattern.

    Missing blocks indicate dot drop-out. Collapsed or inclined blocks indicate dot displacement.

    If dot drop-out or dot displacement is present, proceed to Step 2: Normal Cleaning Method and perform normal cleaning.

    MEMO

    Even if nozzle drop-out does not appear to be improved by cleaning, it may be possible to ignore the effect on products if drop-out occurs in just a few locations. Try printing. If you can judge that the product is not affected, use the printer without any further cleaning.

  4. If you have opened the front cover, close it.
    If no dot drop-out or dot displacement occurs, preparations for output are finished.
  5. Click Close to return to the original screen.
