Memory is insufficient. Close other open applications and try again.
The hard disk does not have
enough available memory.
Check that the hard disk has enough available memory, in particular
when scanning large documents at a high resolution. For example, a
letter-size document scanned at 600 dpi, color requires a minimum
of 300 MB of memory. If you do not have enough available memory,
scan the document at a lower resolution.
The resolution is low. If the image looks grainy, increase the scan resolution.
(See Software Guide, located on your Setup CD-ROM)

display a small image very well.

of a document), specify the area of the scan manually. (See Software
Guide, located on your Setup CD-ROM)
The scanned area does not cover
the entire document.
Place the document approximately 1/8 in. (3 mm) away from the
front and right edges of the platen glass.
