Why, in the Epson driver options (at at least for the 3800) do you get
the warning "Print quality in the bottom area may decline or the area
may be smeared." when you select UltraSmooth Fine Art Paper? EUSFAP is
the only selection that brings up this warning.
My *guess* is that the this paper is too smooth for only the trailing
set of rollers to hold solidly. Most Epson printers have two sets of
rollers gripping the paper, one on either side of the heads, and as
long as both sets (or at least the set before the heads, at which
point the paper is still being restrained by the guides) of rollers
are gripping the paper, it will be positioned accurately. Near the
bottom of the page, only one set of rollers is gripping the paper, and
there's no guide holding the paper in place, so it can easily get out
of position.
In addition, the trailing set of rollers isn't nearly as robust as the
leading set. The leading set of rollers is rubberized, because it's
only gripping bare paper. After the ink is on the paper (and is still
wet), they can't use robust rollers; they just use the pizza wheel
type rollers, which have very little surface area gripping the paper.
