6.
Perform a printing test.
Before you carry out actual printing, perform a printing test to ensure no dot drop-out or dot displacement occurs.
Procedure
1.
Before the start of daily operations, remove just the white ink cartridge, shake it 50 times (about 20 seconds), and
then reinsert it.
So that the ink mixes well, shake the ink cartridge horizontally with a stroke length of around 5 cm (2 in.)
from each end of the ink cartridge.
IMPORTANT
The ingredients in white ink tend to settle. The precipitation of the ingredients in the ink disables printing in normal color. Al-
lowing the ink to stand without carrying out these steps can cause the settled material to harden, resulting in malfunction or
other problems.
2.
Press [FUNCTION].
3.
Press [ENTER].
Printing of the test pattern starts.
4.
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.
The following figure shows the "TEST PRINT 2" test pattern.
5.
If you have opened the front cover, close it.
If no dot drop-out or dot displacement occurs, this operation is finished. Press [FUNCTION] to go back to the
original screen.
MEMO
When performing printing tests successively, you can select ""FEED"" (vertical printing) or ""SCAN"" (horizontal printing) as the
print position for the second and later tests in comparison to the first test.
