If You Cannot Print as Expected
When You Cannot Print Properly
If there are any problems with the print quality, check the following table. If you still cannot print as
expected, contact your authorized Roland DG Corporation representative.
Problem Cause Solution
The images printed soon after
printing starts are blurred or
misaligned.
Because of the time spent in
standby mode, the ink inside the
print head has become viscous.
Before you start printing, print a
test pattern and check for ink
ejection defects such as nozzle
clogging (blurring or drop-out of
printing). For details, see page 46
"Test Printing".
Fading or streaks appear on the
printed image, or the colors mix
during printing.
• Ink is clogged in the print
head nozzles.
• The print head nozzle faces
are dirty.
• The entire bottom plate
and left and right sides of
the carriage are dirty.
• Perform head cleaning. For
details, see page 51
"Cleaning Print Head
Nozzles".
• Clean the maintenance
station. See "Cleaning the
Area around the
Maintenance Station",
Requests for Daily Care and
Maintenance.
• Clean around the print
heads. See "Cleaning
Around the Print Heads",
Requests for Daily Care and
Maintenance.
The printed image is blurred, or
double lines appear on the
image.
The ink drop position is
misaligned between color
nozzles.
Perform [Color Offset]. See
page 92 "Color Offset
Adjustment".
When performing bidirectional
printing, the printed image is
blurred, or double lines appear
on the image.
The forward and backward
printing positions are misaligned.
• If you increase the print
head gap value, use
unidirectional printing.
• Perform [Bi-Dir Offset]. See
page 99 "Adjustment for
Misalignment in
Bidirectional Printing".
