Stripes appear on scan of publication

Cause:	Moiré effect from scan of publication at high resolution (print screen lines
	highlighted by optical interference, producing striped patterns). The appear-
	ance of this effect is dependent upon particular combinations of screen line
	densities and scanning resolutions
Solution:	Rescan at different resolutions (See the ScanGear CS-U User’s Guide
	electronic manual)

Whitened edges on image scanned from thick book

Cause:	Scanner employs an ultra-sensitive scanning unit that picks up ambient light if
	document cover cannot stop light from entering around the edges of the book
Solution:	Cover the book and document glass with a dark cloth to prevent ambient
	light from affecting the scan

Slow scanning speed

Cause:	Resolution is set higher than necessary
Solution:	Lower the resolution.
