The Control Panel
The printer selects the most appropriate setting
automatically. When you use Epson special media,
usually select this setting.
If you want to print on cut-sheet paper that is non-Epson
special media, select this setting.
If you want to print on strongly curled roll paper that is
non-Epson special media, select this setting.
Note:
Make sure that the ink is dry enough on the paper
before the roller touches the media; otherwise, the ink
will soil the roller surface, which stamps on the prints.
If you want to print on roll paper that is non-Epson
special media, select this setting. When roll paper is
selected for the printer, this parameter is selected and
no feed roller is used. If you select this parameter while
using cut sheets, you need to eject the cut-sheet paper
one by one.
