o
Have you tried Feed Adjustment?
Large discrepancies in the feed amount cause
banding (horizontal banding, lines, or strips of uneven
color). Perform Feed Adjustment according to the
media used.
U
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.
o
Is the after heater temperature appropriate?
Raise the temperature if the print results are blurred or
smudged or the ink clots. Note, however, that raising
the temperature too high can cause the media to
shrink, wrinkle, or deteriorate.
In addition, the heaters may require some time to
reach the desired temperature if the ambient
temperature is low. The after heater may also not have
the desired effect after reaching the selected
temperature if the media is too cold. Allow the media
to warm to room temperature before use.
o
Are media settings correct?
Confirm that the media settings in the software RIP or
on the printer match the media actually in use.
o
Is Data Width selected for Head Movement?
Selecting
Data Width
for
Head Movement
in the
setup menu increases print speed but may slightly
reduce print quality. For better quality results, select
Printer Full Width
for
Head Movement
.
U
o
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.
