Question: Why is it my scanned image always comes out
too dark?
Answer: 1) Modify the Gamma setting to 1.8 for your
monitor and, when printing, set Gamma to 2.2
for your printer.
2) Use the Brightness setting of the TWAIN user
interface to get a brighter image.
Question: Sometimes it seems the scanner does not detect
paper?
Answer: The scanner paper sensor is located at the center
of the paper guide. Please place the document
you need to scan on the paper guide and use the
slide guides to keep the paper path straight.
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
a error message.
