Epson 4880 manual Printing with Mac OS

Mode	Description
Paper Feed	Controls the paper feeding value, in 0.01% increments. If
Adjustment	the paper feeding value is too large, white horizontal
	micro banding may appear. If the paper feeding value is
	too small, dark horizontal micro banding may appear.
Paper	This value is set automatically according to the Media
Thickness	Type setting. If you use non-Epson media, modify this
	value for your media. Refer to the paper specifications, or
	see "THICKNESS PAT" on page 126 to print a Thickness
	Pattern to determine the paper thickness.
Paper Suction	Adjusts the Paper Suction value. Decreasing the air
	suction at the platen is useful to avoid wrinkling or waving
	of thin or saturated media, or eliminating vertical
	banding. You can select Standard (100% suction), -1 (50%
	suction), -2 (30% suction), -3 (10% suction), or -4 (6%
	suction).
Cut Method	Determines the best cutting method according to the
	paper thickness. You can select Standard (normal speed
	and normal cut pressure), Thin Paper (low cut pressure),
	Thick Paper, Fast (high speed and high cut pressure), or
	Thick Paper, Slow (low speed and high cut pressure)
Platen Gap	The platen gap is the distance from the media loaded in
	the printer to the print head. By adjusting this setting, you
	can increase the print quality. This is set automatically
	according to the Paper Thickness setting specified.
	Note:
	Setting Platen Gap to Narrow may produce better print
	quality, but make sure the media does not wrinkle or
	touch the print head; otherwise, the printout or the print
	head may be damaged. If this happens, select the Wider
	or Wide setting.
Eject Roller	Select the Eject Roller Type that best fits your media.
Type	Auto: The printer selects the most appropriate setting
	automatically. When you use Epson special media,
	usually select this setting.
	Starwheel-Sheet: If you want to print on cut-sheet paper
	that is non-Epson media, select this setting.
	Starwheel-Roll Curled: If you want to print on strongly
	curled roll paper that is non-Epson media, select this
	setting.
	No Roller-Roll Normal: If you want to print on roll paper
	that is non-Epson media, select this setting.
Default button	Click this button to return the settings to their factory
	default values.
