The scanner software does not work properly.
Be sure you have correctly installed your software.
Check that the system requirements, such as the operating
system version, are correct for using your software.
See if the computer has enough memory for your software. If
you are running other software at the same time, using RAM
resident programs, or have many device drivers, the computer
may not have enough memory remaining. (gee your software
and computer manuals.)
Make sure that your software supports this model of scanner
and that you correctly installed or set up the software. (gee
your software manuals.)
The entire image is distorted or blurred.
Make sure that the document is placed flat against the
document table (the glass area).
You may have accidentally moved the document during
scanning. Check the position of the document and do not move
it while the scanner is operating.
See that the scanner is not tilted or placed on an unstable
surface.
