Paper port error: "twain device not found"

[bdlong]

I have done a google search and tried a variety of things, but nothing
is working.

Scanner - Brother MFC 6800.
Can scan through "scanners and cameras" and the "Smart UI" which comes
with Paperport 8SE. However, everytime I try to scan inside of
Paperport it gives me an error message:
"problem communicating with twain device".

I have completely uninstalled the Brother and the Paper port
software.
Went into device manager - showed the hidden components and deleted
anything related to the scanner.

rebooted the workstation and reinstalled everything. The scanner is
working properly, so what gives with the Paper port program? Any
suggestions?

thanks

I assume that you have gone through the Paper Port Scanner Setup wizard.

If not run the Scanner Setup Wizard, it should be in the Start Menu along
with Paper Port.

Are you sure that the brother scanner has a TWAIN interface and you are not
using the WIA interface?

There wasn't a scanner setup wizard in the start menu, however, there
is a initwain.exe in the paper port menu that the support website
mentioned to run. (i have ran it a few times).

The only scanner that shows up is the WIA-Brother. The support site
mentions to choose the non-wia scanner, but it's not there.
A litte background - it was running fine on this computer, another
indication it isn't the hardware. I replaced the hard drive with a
new SATA drive and did a fresh install of Windows. I haven't been
able to get the scanner to run properly using Paper Port since. I
believe I remember the old hard drive using the twain scanner and not
the Wia version.

The Wia version is probably supplied by Windows XP, Windows XP does have
some built-in drivers for scanners, usually WIA. Paperport uses a TWAIN
driver, not WIA.

You must find a TWAIN driver for your Brother scanner.
Here are the drivers for Brother MFC 6800

If that machine has a parallel and usb port use the USB not the parallel
port.

Been there, done that, have the tshirt, but the scanner still doesn't
work. :-(
I had the CD with the installation files, but when that didn't work I
had went to their website and downloaded it. I also downloaded their
uninstall and when through the process of uninstalling then
reinstalling. thanks for your suggestions though. For some reason,
it doesn't want to load/install the twain drivers.

You must remove any WIA driver that is currently installed, open Device
Manager and remove anything that says brother WIA in the Imaging devices
branch.

Then, you may have to do it the 'hard' way.
Uninstall the brother software, then search in regedit for all entries on
the Brother unit.

After a reboot, try installing the software again.

I do have one question, do you have any other TWAIN device on that computer
that works?

It is possible that the TWAIN system in Windows XP is messed up.
There are four files in the TWAIN system that can be expanded from the
Windows XP install CD.

The four files are:
twain.dll
twain_32.dll
twunk_16.exe
twunk_32.exe

They are located in the %SYSTEMROOT% folder, usually C:\Windows.

To find out how to restore those files, search Help and Support for "expand"
