NOTE: This is the default setting for all
trays.
For the first few sheets of paper that it picks up from the tray, the product detects
light paper, plain paper, heavy paper, glossy paper, tough paper, and
transparencies. The product assumes the rest of the pages are of the same type.
Transparency only The product distinguishes between transparencies and non-transparencies. This
setting provides the fastest printing, but for some paper types it might reduce print
quality.
