Uneven printed
colors
The setting value of
"Banding reduction" is
inappropriate.
When using an Epson printer driver, color lines generated
in the overlapping print head parts can be corrected as
shown below by selecting "Banding reduction" so that
uneven printed colors may not stand out.
Select "Detailed settings" in "Print settings" of the
"General" tab, push the "Settings" button and change
the dark and light setting with "Banding reduction".
(When light color lines are generated as shown in the left
figure, move to the plus (+) direction to adjust. Also,
when dark color lines are generated as shown in the
right figure, move to the (-) direction to adjust.)
For details, refer to "Banding Reduction" on page 135
Also, if the "Nozzle Verification Technology" in "Nozzle
check settings" is disabled, change to enabled (default).
Roll paper is not set

For the roll paper, open the roll paper cover and reset

Printed colors do
not look right.
A head cleaning is
necessary.
When the printer is moved after initial charging, there
may be cases that specified colors are not printed out
right ("Color mixing") due to vibration or shock.
Execute a manual head cleaning and check that the
color mixing no longer occurs.
