The prints are not what you
expected
Print quality is poor, uneven, too
light, too dark, obvious graininess, or
the tone differs.
Are the print head nozzles clogged?
o
If the nozzles are clogged, specific nozzles do not fire
ink and the print quality declines. Try printing a test
pattern.
"Printing nozzle check patterns" on page 81
U
Perform Head Alignment.
o
Given that there is a slight gap between the print head
and the media, the landing sites for the different
colors of ink may be affected by humidity,
temperature, inertial forces imparted by the print
head, the direction of the print head as it moves from
right to left or left to right, or the use of two print
heads. As a result, the printing result may show
obvious graininess or out-of-focus characteristics.
Select Media Adjust - Head Alignment in the media
settings to adjust a print head misalignment that
occurs during printing.

Perform Feed Adjustment.
o
Large discrepancies in the feed amount cause
banding (horizontal banding, tint unevenness, or
stripes). Select Media Adjust - Feed Adjustment in
the media settings to make adjustment based on the
target media.

U
Are you using a genuine Epson ink pack?
o
This printer is developed for use with Epson ink packs.
If you use non-Epson ink packs, printouts may be faint,
or the color of the printed image may be changed
because the remaining ink level is not correctly
detected. Be sure to use the correct ink pack.
Are you using an old ink pack?
o
The print quality declines when an old ink pack is used.
Use all the ink completely either by the expiry date
noted on the ink pack or within 25 days from the day
on which the ink tank was refilled.
Are the heaters at the correct temperature?
o
Raise the temperature if the print results are blurred or
smudged or the ink clots. Note, however, that raising
the temperature too high can cause the media to
shrink, wrinkle, or deteriorate.
In addition, the heaters may require some time to
reach the desired temperature if the ambient
temperature is low. The heaters may also not have the
desired effect after reaching the selected
temperature if the media is too cold. Allow the media
to warm to room temperature before use.
Are media settings correct?
o
Confirm that the media settings in the software RIP or
on the printer match the media actually in use.
Is Data Width selected for Head Movement?
o
Selecting Data Width for Head Movement in the
setup menu increases print speed but may slightly
reduce print quality. For better quality results, select
Printer Full Width for Head Movement.
