Possible Solutions
Make sure the resolution of the scanner is not set
too high. A range between 75-200 should work
fine.
Set the Parallel Port Mode inside computer's
BIOS to EPP (enhanced parallel port).
Make sure all filters are deselected inside
TWAIN.
Check that printer cable is properly secured to
printer and scanner.
Make sure printer is turned on.
Turn off the computer and the printer. Make sure
that the scanner is plugged into a constant power
source (leave scanner on at all times). Turn the
computer on and enter Windows. Once inside
Windows turn on the printer and try printing a
document.
Disable the "Bi-directional" option of the printer.
Reset the computer (turn it off and on).
Unplug the power cable from the rear of the
scanner and open the scanner's lid. Looking at the
front of the scanner while the lid is open plug the
power cable back into the scanner. If the light
turns on and off quickly, the scanner is properly
working.
Please see http://www.plustekusa.com and the
Knowledge Base for more information.
The scanner's light source is designed to stay on
for 30 minutes. To turn off the scanner's light,
enter the Scanner Utility and choose the Lamp
Control tab.
