What to do
Are the print head nozzles clogged?
If the nozzles are clogged, specific nozzles do not fire ink and the print quality declines.
Print a nozzle check pattern.
"Nozzle Check" on page 113
U
Was Head Alignment performed?
With bidirectional printing, the print head prints while moving left and right. If the print
head is misaligned, ruled lines may be misaligned accordingly. If vertical ruled lines are
misaligned with bidirectional printing, perform Head Alignment.
"Correcting Print Misalignment (Print Head Alignment)" on page 117
U
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.
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 the ink cartridge before the expiry date printed on
the packaging (within six months after installing in the printer).
Are the Media Type settings correct?
Print quality is affected if the Media Type you have selected in the Main screen (Windows)
or Print screen (Mac OS X) in the printer driver does not match with the paper that is loaded
in the printer. Be sure to match the media type setting with the paper that is loaded in the
printer.
Did you select a low quality mode (such as Speed) as the Print Quality?
The print quality may decline when you select Speed for Print Quality or make Quality
Options settings that assign priority to speed from the printer driver. If you want to
improve your print quality, select a setting that assigns priority to quality such as Quality
or Max Quality.
Was color management performed?
Perform color management.

U
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.
Did you open the printer cover while printing?
If the printer cover is opened while printing, the print head stops suddenly causing
unevenness in the color. Do not open the printer cover while printing.
Is Ink Low displayed on the control panel's 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.
