4.

Problem:
Your parallel port mode is set incorrectly. The parallel port mode
can be set using SPP (Standard Parallel Port) or EPP (Enhanced
Parallel Port). If your port is set to SPP, it can only support one
parallel device (usually a printer). EPP mode allows the parallel
port to control more than a single device. To control both the
scanner and the printer using the parallel port you need to change
the port setting to EPP.
Solution:
Follow the steps below to change your parallel port mode, if you
are familiar with editing your BIOS settings:
1.
Go to the Peripherals section and find the Parallel Port Mode
setting.
2.
Change the setting to ECP or EPP.
3.
Save the changes and exit the BIOS.
4.
Cycle the scanner power by unplugging the power adapter cord
from your scanner, then plugging it back in to the wall outlet.
5.
Reboot into Windows.
At this point, your computer should recognized by your scanner. If
you are still having problems you can try different modes, one at a
time, (cycling the scanner power after each change).
