Attractive Printing Is Impossible
Printed results are coarse or contain horizontal stripes
Do the print heads show dot drop-out?
Carry out a printing test and make sure no dot drop-out occurs. If dot drop-out is present, perform cleaning
of the print heads.

Is the print mode suitable?
Try an appropriate print mode. Specific combinations of media and print mode may cause the colors to be
uneven, and results may also vary greatly depending on the settings of your RIP & PRINT MANAGEMENT SOFT-
WARE (such as the color-profile selection). Select settings appropriate for the media you are using.
Is the printer installed in a level and stable location?
Never install the machine in a location where it is tilted or where it may wobble or experience vibration. These
factors may lead to dot drop-out or reduced printing quality.
Is the printer installed in a location that is not exposed to direct sunlight?
Never install the machine in a location that is exposed to direct sunlight. Doing so may result in dot drop-out
or reduced printing quality and may even result in malfunctions.
Is the media loaded and set up correctly?
If the media is not loaded correctly, printing may be adversely affected. Make sure the media is loaded and
set up correctly.

Colors are unstable or uneven
Did you shake the ink cartridges before installing them?
Shake new ink cartridges 50 times (about 15 seconds) before you install them.
Has the printer been used for a long time?
If, during use, the white ink concentration becomes low, use the [CIRCULATE INK] function.
P. 64, "Restoring the White Ink Concentration"
Was printing paused partway through?
When printing is paused, the coloring at the seam may be altered when printing resumes. Avoid pausing
printing. With the factory default settings, printing pauses when an ink cartridge becomes empty. Printing
may also pause when data is not sent from the computer quickly enough. We recommend not performing
any other tasks with the computer while printing is in progress.
