Computer can't find scanner

I have been using this scanner on my system for over a year. Suddenly, each time I try to scan something I get a message - Cannot communicate with scanner - it may be turned off or unplugged. - It is not. The printer will work without a problem. Any ideas?

You don't say which type of computer and operating system you are using. However, the answer is similar, regardless of the computer you're using. You probably updated your operating system, and the Agfa software no longer works. Depending on your operating system, there are various solutions you can use. Agfa no longer supports their scanners with new drivers or updated software. That's too bad, because they made some really good scanners for years.
A common solution I'm seeing on Mac, Linux, and PC platforms is to download and install SANE files on your computer and use graphics software, a different scanner program, or a direct interface with the scanner to continue using it. I'm on a Mac, and I'm using the Scan functions in Graphic Converter 7. I understand VueScan, OmniPage, Image Capture, PhotoShop (under some circumstances), and even Word will work, if the SANE files are properly set up. What works for you will depend on your own system.

The scanner has a separate driver as does the printer portion. They are installed separately. Download the scanner driver or re-install the disc that came with your printer.

My scanner won't scan. I get the message " Scanner is busy, operation can not be completed. Canon DR-2010C Driver Version 1.1.10805.18001 (-4437).


This may mean that something is using it or that something is interfering with it. Try turning everything off, your computer AND your scanner. Wait a minute or two and then turn your scanner on first and the turn your computer back on. When your computer boots back up don't open anything except the scanner. If your still getting the message then there is something else (another attached peripheral) that may be interfering with the scanner.

Tried to print something from the glass, got error message


this is usually the case when certain settings that are required by the registry are not in place, The solution could be as simple as unistall the scanner driver restart the system and reinstall the scanner driver.

If this doent work get back old registry values by going to start-Programs-accessories-system tools -system restore and restore the settings to the time when youre sure the scanner worked .

Try to print--scanner failure appears


I think your printer has been, for some time now, trying to tell you something and the scanner failure message
is the last in a series of messages.

First, the copier and the printer and the scanner worked fine, "for years",
Then, the copier stopped accepting scans, while printing from data sent by your computer.
Then, you received a scanner failure message again, and will not accept data from your computer, and
"won't print at all"

Your printer/scanner/copier/fax has needed service for some time after years of continuous service.

Evaluate now, based on its initial cost and the lesser cost of All In Ones whether you have already
obtained sufficient service to amortize the cost over time, and you may conclude that service is eitherr
cost effective or ineffective at this time.
