Can't get TWAIN driver recognized by Canon CanoScan N670U

[Hank Arnold]

I've been running with this scanner just fine since I got it and installed
it (running WinXP Pro). I recently set up a new partition to re-build my
setup (I do it once or twice a year). For some ungodly reason, I simply
can't get the damned TWAIN driver to be recognized.

I downloaded the latest driver file (CanoScan_N670U_v7010.exe) and installed
it, apparently with no problems. There was no indication of successful
installation, it just finished. The scanner was successfully recognized when
I plugged the USB cable in. It shows up in Device Manager as "working
properly". However, when I try to install the Software (ScanGear CS-U,
etc.), it tell me that the TWAIN driver isn't installed. Any ideas?

Check your Device Manager for any Yellow marks on the Scanner entry.
If there is any, delete the entry, re-boot computer and install the software
again.

Thanks. I finally got it to work. The instructions kept telling me to insert
the "CanoScan Setup Utility CD-ROM" and all I had was the "Software
Solution" CD. I figured I had lost the CD and was trying to manually
download and install the drivers. When I finally browsed the CD I had, it
had what looked like install files (*.inf), so I just followed instructions
and inserted the CD I had. Worked first time after that....

I've got a similar problem with my CanoScan N1220U. Device manager
lists it as an unknown device. The TWAIN driver is not recognized so the
software suggests I install the driver before proceeding. I've tried
installing the .inf file from the CD, unsuccessful. I've tried installing
from the C:\temp\CanoScan........ file per instructions found on CD.
Nothing seems to work. I'm really at a loss. Any help would be greatly
appreciated.

Hi This post 19/06/2011

For those who are still having problems, you need to download a compressed file deldrvwin1242ejf driver from dell.
This deletes the USB driver and installs the missing TWAIN.

Still stuck? Email me on (e-mail address removed) - put TWAIN in subject.
