The prints are not what you expected

Cause What to do

Print quality is poor, uneven, too

light, or too dark.

Are the print head nozzles clogged?

If the nozzles are clogged, the print quality is reduced. Print the nozzle check pattern.

If you replace the ink cartridges while the printer is turned off, the remaining of the ink

cannot be detected correctly so that the Ink Check light is not on even the ink cartridge

is needed to be replaced or you cannot print correctly. Be sure to follow the

instructions in this manual to replace the ink cartridge.

See “Replacing Ink Cartridges” on page 64

Is there any gap in the print head during bidirectional printing?

With bidirectional printing, the print head prints while moving left and right. If the

print head is misaligned, ruled lines may be printed misaligned with gaps. If vertical

ruled lines are misaligned with bidirectional printing, adjust the gap.

See “Print head alignment” on page 79

Are you using a genuine Epson ink cartridge?

If you use the non-Epson ink cartridge, the prints may smear, or the color of the printed

image may be changed because the ink remaining is not correctly detected. Be sure to

use the correct ink cartridge.

Are you using an old ink cartridge?

The print quality decreases when an old ink cartridge is used. Replace the old ink

cartridge with a new one. Be sure to use the ink cartridge before the expiry date

(within six months after installing to the printer).

Is the media type setting correct?

It affects the print quality if the paper you have selected in the Main menu (Windows)

or Print Settings dialog (Mac OS X) 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 Speed for Print Quality?

The print quality may decrease when you select Speed rather than Quality. If you want

to improve your print quality, select Quality for the Print Quality setting in the Main menu.

Have you made color adjustment settings?

The color is produced differently because the output devices (such as display, printer)

are different. In order to reduce the differences in color between each device, perform

color adjustment.
