Print Quality/Print Results

Print quality is poor, uneven, too
light, or too dark.
Are the print head nozzles clogged?
o
If the nozzles are clogged, specific nozzles do not fire
ink and the print quality declines. Check whether the
nozzles are clogged.
"Checking for clogged nozzles" on page 98
U
Perform print head cleaning if the nozzles are
clogged.
"Head Cleaning" on page 99
U
Was Print Head Alignment performed?
o
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 Print Head Alignment.

U
Alignment)" on page 100
Are you using a genuine Epson ink cartridge?
o
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?
o
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?
o
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.
Problem Solver
Did you select a low quality mode (such as
o
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.
Was color management performed?
o
Perform color management.
"Color Management Printing" on page 86
U
Have you compared the printing result with
o
the image on the display monitor?
Since monitors and printers produce colors
differently, printed colors will not always match
on-screen colors perfectly.
Are you printing with PhotoEnhance (auto
o
print quality adjustment)?
PhotoEnhance optimally enhances data that lacks
appropriate contrast or saturation for clear results
when printing. As a result, colors in images printed
with PhotoEnhance may differ from those displayed
on screen.
"Auto Correct Color and Print Photos
U
(PhotoEnhance)" on page 54
Did you print a photograph or other color
o
image on plain paper?
The type of paper used for color printing has a large
effect on the quality of the results. Choose a paper
(including special medias and plain paper) according
to your intended purpose.
Did you print on the wrong side of the paper?
o
Special medias have a back (non-printable) side. Place
the front (printable) side on top.
The color is not exactly the same as
another printer.
Colors vary depending on the printer type
o
due to each printer's characteristics.
Because inks, printer drivers, and printer profiles are
developed for each printer model, the colors printed
by different printer models are not exactly the same.
You can achieve similar colors with the same color
adjustment method or the same gamma setting by
using the printer driver.
