Here are the basic points, please refer to the signs posted at each scanner/copier for more specific instructions.
-only two of them (STL and in front of ILL)
-cost is free...but card with value on it must be inserted
-default is pdf (jpg is an option)
-user must select orientation (same as choosing a copy...letter portrait, letter landscape, etc)
-nothing
is saved to the usb until the user presses the "#" sign. So with a
pdf...most people scanning in an article will want to scan repeatedly
until the article is done...then press "#" sign. This will give them the
whole article in one pdf.
