o
Has the printer been left unused for a long
time?
If the printer has not been used for a long time, the
nozzles may have dried up and have been clogged. If
the printer has been left unused for an extended
period, check that the print head nozzles are not
clogged before resuming printing. If the nozzles are
clogged, perform head cleaning.

Print Quality/Print Results

light, or too dark.
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 nozzle
check pattern.

o
Are you using a genuine Epson ink cartridge?
This printer is developed for use with Epson ink
cartridges. If you use non-Epson ink cartridges, the
prints may smear, 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.
o
Are you using an old ink cartridge?
The print quality declines when an old ink cartridge is
used. Install a fresh ink cartridge. We recommend
using the ink cartridge before the expiry date printed
on the packaging (within six months after installing in
the printer).
o
Are the Media Type settings correct?
Print quality will be affected if the paper currently
loaded in the printer does not match the
Media Type
selected in the printer driver
Main
tab (Windows) or
Print screen (Mac OS X). Be sure to match the media
type setting with the paper that is loaded in the
printer.
o
Is Off selected for Auto Ink Density
Optimization?
Inconsistencies may develop in the density of the ink
inside the cartridges when Off is selected for Auto Ink
Density Optimization. Perform Ink Density
Optimization.
U
“Performing Ink Density Optimization” on

Ink Density Optimization.

o
Is print speed currently prioritized over print
quality?
Print quality may decline slightly if priority is given to
speed using
Print Quality
-
Quality Options
in the
printer driver. For better quality prints, choose
settings that assign priority to quality.
o
Was color management performed?
Perform color management.
U
“Color Management Printing” on page 71
o
Have you compared the printing result with
the image on the display monitor?
Since monitors and printers produce colors
differently, printed colors will not always match
on-screen colors perfectly.
o
Is there enough ink?
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.
The amount of ink remaining can be viewed in the
EPSON Status Monitor window.
