Steps to take when the printer has not been used
for a long time
U
The prints are not what you
expected
Print quality is poor, uneven, too
light, too dark, obvious graininess,
or the tone differs.
o
Are the print head nozzles clogged?
If the nozzles are clogged, specific nozzles do not
fire ink and the print quality declines. Try printing a
test pattern.
U
“Printing nozzle check patterns” on page 81
o
Perform Head Alignment.
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.
U
o
Perform Feed Adjustment.
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
o
Are you using a genuine Epson ink pack?
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.
o
Are you using an old ink pack?
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.
o
Are the heaters at the correct temperature?
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.
o
Are media settings correct?
Confirm that the media settings in the software RIP
or on the printer match the media actually in use.
o
Is Data Width selected for Head Movement?
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
.
