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,
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.
o
Are you using an old ink cartridge?
The print quality declines when an old ink cartridge is
used. Replace the old ink cartridge with a new one. We
recommend using all the ink in the cartridge before
the expiry date printed on the package (within six
months of installation).
o
Have the ink cartridges been shaken?
The ink cartridges for this printer contain pigment
inks. Shake the cartridges thoroughly before
installing them in the printer.

Are the Media Type settings correct?
Print quality can be affected if the media settings in
the printer driver/on the printer and the actual paper
do not match. Be sure to match the media type setting
with the paper that is loaded in the printer.
