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 6 months of installation in the
printer).
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.

Is the Media Type setting correct?
Print quality can be affected if the media settings in
the printer driver/on the printer and the actual

type setting with the paper that is loaded in the
printer.
o
Did you select a low quality mode (such as
Speed) as the Print Quality?
If the options selected for
Print Quality
>
Quality
Options
place priority on speed, quality will be
sacrificed for print speed, potentially causing print
quality to decline. To improve print quality, select
Level
options that give priority to quality.
