o
Are you using a genuine Epson ink pack?
The printer is designed for use with the genuine Epson
ink packs specified in this manual. Using any other
type of ink pack may result in reduced print quality.
We recommend using only the genuine ink packs
specified in this manual.
o
Are you using an old ink pack?
The print quality declines when an old ink pack is used.
Use a new ink pack. Use all the ink in the ink pack
before the date printed on ink pack.

Are media settings correct?
Confirm that the media settings in the software RIP or
on the printer match the media actually in use.

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.
o
Was a printer cover opened during printing?
Opening covers during printing causes the print head
to stop abruptly, resulting in uneven colors. Do not
open the covers while printing is in progress.
The print is not positioned properly
on the media.

Is the media loaded correctly and are the
margins correct?
If the media is not loaded correctly, the results may be
off center or part of the data may not be printed. You
should also check whether the correct options are
selected for
Side Margin
and
Print Start Position
in
the setup menu.
