Problems with P-215

If you run the P-215 scanner driver installer again you will get the ds file. But if you have trashed the Image Capture folder in the root Library then I don't think this installer will recreate this folder. Do you have a Time Machine backup that you can restore the folder from?

I added the folder back (it wasn't in my time capsule back-up as this was only going back recently) so I added it from my Mac Mini.

I deleted and re-ran the installer for 215_MacDR_V11_COT_V12_GooglePlugin_V11.dmg

The scanner is not detected, and there is no driver file in the image capture folders.

Does the Mac see the P-215? Open System Information and select USB in the left column. The top right pane will show all the USB busses on the Mac. The P-215 should be listed under one of these busses.

As for the P-215.ds file not being present in the TWAIN Data Sources folder, check what Permissions are set on the folder. System should have Read & Write. Since you copied the Image Capture folder from another Mac then this could be the issue.

I ran (unexpected, and ofcourse mid-tax season) into the same problem.
The P-215 always worked great under 10.8.x but now refuses to work in 10.9.x (when accessed through Twain etc in 3rd party applications like Adobe Acrobat X).

This is how I got it to work again ... note that updating the driver might not be needed, but I cannot confirm that.

Install latest driver

First thing I did (not sure if it's needed) is removing the p-215.ds file from "/Library/Image Capture/TWAIN Data Sources" and installed the "latest" driver (http://software.canon-europe.com/products/0011064.asp) for MacOS X 10.9.

Upgrade scanner Firmware

As this updating the driver didn't fix the problem, I upgraded the firmware as well.

Sadly, the update application runs only under Windows, so I had to either find a Windows computer or use Paralells Desktop or VMWare Fusion (I ended up using Parallels Desktop w/ Windows 8.1).

You can find the firmware on the Canon website, but strangely enough the European Canon website has more to offer: http://software.canon-europe.com/products/0011064.asp

After updating the firmware and exiting the virtual Windows machine, I did disconnect (USB and power) the scanner as suggested by the software and reconnected everything again.

After that the scanner worked again! 😎

Here are the Canon P-215 drivers for 10.9.x via Canon Europe:

http://software.canon-europe.com/software/0043931.asp

This is the TWAIN Driver v1.2 & CaptureOnTouch v1.3 & GoogleDocsPlug-In v1.2 for Mac (10.5x-10.9x) which was released on 01/04/2014.

Thanks for that information...I've installed and sadly it seems like my p-215 won't work. It is just not recognised by the software (although the light is on).

After installing the driver, make sure to flip the switch in the back of the P-215 to the off position so that it doesn't load its built-in software as a virtual disk. If the switch is in the on-position, then the P-215 won't be recognized by the new driver.

After quite a bit of research I found this forum discussion on Mac Rumours that tells you how to fix the issue: http://forums.macrumors.com/showthread.php?t=1340029, specifically installing TwainBridge from Mountain Lion here: http://janegil.net/2014/01/twain-scanners-in-os-x-maverick/ Worked for me! Hope you have similar positive results.

This seems to fix it:

Apple today released an iMac Graphics Update for users of the more recent iMacs, fixing an issue that caused the computers to freeze up after viewing very large JPEG Files.
