THICKNESS NUM
If you use Epson special media, you should normally select AUTO.
If you use non-Epson special media, confirm the paper thickness
detection pattern, and enter the number for the print pattern with
the smallest gap.
CUT METHOD
You can specify the cutting method. There are four ways to cut
paper, STANDARD, THIN PAPER, THICK, FAST, and THICK, SLOW.
PPR FEED ADJ
You can set the paper feed amount. The range is -0.70 to 0.70%.
EJECT ROLLER
You can select AUTO, SHEET, ROLL CURLED, or ROLL NORMAL.
AUTO
SHEET
ROLL CURLED
ROLL NORMAL
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 which is non-Epson
special media, select this setting.
If you want to print on strongly curled roll paper which
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 mess the roller surface, which stamps on the prints.
If you want to print on roll paper which 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 sheets one
by one.
