Thanks for the reply. I have downloaded M140DRIT_V11SP5.exe twice with the same result. The scanner shows up in Devices but does not show in any other scanning application. Clicking on the scanner in Devices causes the WIA driver message to show.
I'll try the other diagnostic steps tomorrow when I get back to the offending computer.

> does not show in any other scanning application

Which scanning apps have you tried?

> I'll try the other diagnostic steps tomorrow

OK. In the meantime, I'll research that WIA message, which I don't recollect ever seeing.

Based on some web research, it seems that some Canon scanners support only TWAIN and ISIS, not WIA. This is bolstered by the description of the driver at the Canon site for your model, which says:

"DR-M140 ISIS/TWAIN Driver version 1.1 SP5 for Windows XP SP3 & 64bit SP2 (WOW), Vista 32bit SP2 & 64bit SP2 (WOW), Windows 7 32bit SP1 & 64bit SP1 (WOW), Windows 8 32bit & 64bit (WOW)."

WIA is noticeably absent! One user said he sent an email to Canon support about this issue and here's the response from them:

"When scanning, you will need to use a scanning program such as CapturePerfect (included with the unit) or some other program that supports the industry standard TWAIN or ISIS interface(s). The WIA interface used by the Devices and Printers Scanner Wizard is not supported by the scanner driver, thus the Scanner Wizard does not connect with the scanner."

So if this proves to be true, you'll need to use a scanning app that supports ISIS or TWAIN, which most imaging/scanning apps do, but the scanner won't be accessible via Devices and Printers, which uses WIA. I did find a thread with a supposed work-around, but the technique doesn't thrill me:

You may want to give a try...I wouldn't...but, then, all of the imaging/scanning apps I use support ISIS and/or TWAIN. I'm very interested in hearing what happens when you try IrfanView, which supports TWAIN. I'm guessing Paint won't work, because that supports just WIA. Regards, Joe

I don't want to edit that again, because I've had to upload the attachment 3 times now. It appears there is no harm done if you extract and run the repair even if you don't need it... if the repair tool doesn't find an inconsistency, it just exits with a 'no problem found' message.

Actually ISIS is the protocol I want to use. The app that I am using (an insurance industry app) uses the ISIS protocol. That app does not "see" the scanner even though it appears in Devices and Printers. I'll test tomorrow with other apps.

I know for a fact that PaperPort 14 supports ISIS...I use it every day with a Kodak scanner and its ISIS driver. You may download a free 15-day trial of PP14 here:

Give it a shot to see if it works with the DR-M140's ISIS driver. Regards, Joe

Did you click on and peruse the READMEFIRST.pdf file?

ASKER

Not a new scanner. Companion CD not available.

The READMEFIRST.pdf file's attached to message http:#a38816883 ;
The registry repair Utility is downloadable from canon's web site (link is also in that message... no direct link to the file available, because you have to click the I Agree button on their download page to get it).

ASKER

Ok. Will try today. Thanks

ASKER

Checked registry. WIA in registry is consistent. Both 0000
Tested with IrFanView. Twain for the offending scanner appears in selection screen. That would lead me to believe my insurance app would also recognize the scanner (at least in Twain mode). It does not so I am directing my attention to the app rather than the scanner. More as I test further.

> It does not so I am directing my attention to the app rather than the scanner.

Excellent troubleshooting step!

> the offending scanner appears in selection screen

Beyond just recognizing the scanner/driver, you should see if IrfanView can initiate a scan. After selecting it as the Scan/TWAIN source, click [Acquire/Batch Scanning...] and perform a scan with it. If that works, then it's even more certain that the problem is with the app, not the scanner or scanner driver. Regards, Joe

Like so many issues surrounding peripherals the symptoms don't always suggest the cure. Thanks for getting me on the right track.
