Many databooks I find are printed on the fragile "telephone book" type
paper, either transparent, beige or both. Do you have any techniques
for getting good images out of those, and making sure they survive the
trip through the ADF?
Always scan those monochrome. (A lot of people insist on color scanning
of black and white materials)
Some scanners have a built-in red filter that helps with yellowed paper.
Transparent/translucent materials will often do substantially better with
a black pressure pad on the back, instead of white.
