Question:

When I choose optical resolution to

be 600 dpi, the "auto crop" and

"deskew" functions will be

disabled.

Answer:

Since to perform auto crop and deskew

consumes great deal of system

memory, it is suggested if you wish to

perform "auto crop" and "deskew"

functions, please choose your optical

resolution to be smaller than 600 dpi

to prevent an error message.
