page 25
The prints are not what you
expected
Print quality is poor, uneven, too
light, or too dark.
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.
"Checking for clogged nozzles" on page 75
U
Was Head Alignment performed?
o
Select Head Alignment to realign the print head when
print results seem grainy or out of focus.
"Correcting Print Misalignment (Head
U
Alignment)" on page 66
Have you tried Feed Adjustment?
o
Large discrepancies in the feed amount cause
banding (horizontal banding, lines, or strips of uneven
color). Perform Feed Adjustment according to the
media used.

U
Are you using a genuine Epson ink cartridge?
o
This printer is developed for use with Epson ink
cartridges. If you use non-Epson ink cartridges,
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 cartridge.
Problem Solver
Are you using an old ink cartridge?
o
The print quality declines when an old ink cartridge is
used. Replace the old ink cartridge with a new one.
Use all the ink in the cartridge before the date printed
on the package or within six months of opening,
whichever is sooner.
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. U
Setup Menu" on page 104
Have you compared the printing result with
o
the image on the display monitor?
Since monitors and printers produce colors
differently, printed colors will not always match
on-screen colors perfectly.
Was a printer cover opened during printing?
o
Opening covers during printing causes the print head
to stop abruptly, resulting in uneven colors. Do not
open the covers while printing is in progress.
Is Ink Low displayed on the control panel's
o
screen?
The print quality may decline when the ink is low. We
recommend replacing the ink cartridge with a new
one. If there is a difference in color after replacing the
ink cartridge, try performing head cleaning a few
times.
