Error message with my Canoscan 5000: TWAIN error

[annemg211]

     I realize my scanner is older, however I never had problems until recently. I uninstalled and reinstalled software for my Canoscan 5000/5000F. When I go to try a scan, I get a message on the screen that says: There is a TWAIN error. Make sure your device is connected. It is. Now what? My attempts at fixes thus far have been unsuccessful. Am I out of luck?

Hi, annemg211!

So that the Community can help you better, we will need to know exactly which operating system is running on your computer. That, and any other details you'd like to give will help the Community better understand your issue!

Thanks and have a great day!

     I am running Windows XP on my PC with 2.0 GB of RAM, which hasn't changed from when my scanner WAS working. Does this help?

Hi annemg211,

Is your scanner plugged directly into your computer, or is it plugged into a USB hub that is plugged into your computer?  

If this is a time-sensitive matter, additional support options are available at Contact Us.

The USB cable has been plugged into an "external" (multi-ended) USB port AND tried directly into the computer's USB hub. All the plugs have been unplugged and replugged. There is realistically no power coming thru the scanner. Software was all reloaded and does not recognize the scanner even being connected. No damage to any cords nor problems with anything else connected to the power source or USB hubs.

 1.  Right-click on Computer (from the desktop or start menu) and choose 'Manage'.

 2.  In the Computer Management Window, highlight Device Manager on the left.

Hi I am new here & could not find how to write a question. I have the same problem as the person above.

I have a new Dell Vostro PC with Windows 10 Pro. I have a ConoScan 5000F Scanner.

( I had it previously installed on my Shuttle PC that had Windows 10 which died.) It worked fine before the computer died.

I installed the CD & software from the Canon CD.  All the software works fine. When I click on Acquire I get Twain error, "Maybe the divice is not connected". The Scanner does not work.  When I checked the Divices & Printers I see this:

"The drivers for this device are not installed. (Code 28)" I checked your CanoScan 5000F page I see NO Driver available; what  do I do now? Please help me.

Thank you, VNV1
