Lost Canon Scanner in system Preferences

Have Canon Scanner 9000f mk 11.connected via USB. It seems to have disappeared from System Preferences although it's showing as connected in System Report. I can still use it thru. Scan Gear and Image Garden but I preferred using it thru. the OS. I prefer the interface. Tried rebooting and reconnecting USB to no avail. It was working fine yesterday. Must have clicked something I shouldn't have. The OS. seems to have lost track of it.

Any ideas would be welcomed. Thanks.

iMac, OS X El Capitan (10.11.5)

Are you saying that it is not listed in System Preferences -> Printers & Scanners?

Thats right. If I click the +button the system can;t find any scanners attached yet if I go into About this Mac/System Report it's listed there.

My Canon printer is listed in System Preferences.

The appearance of the scanner icon in Printers & Scanners relies on an ICA driver. Canon has two drivers available for this scanner; an ICA and a TWAIN driver. The TWAIN driver works with the Canon applications, ScanGear and My ImageGarden, but this driver does not make the scanner icon in Printers & Scanners. The ICA driver, which does make the icon in Printers & Scanners, is for use with applications like Image Capture and Preview. Sounds like you have an issue with the ICA driver, or a recent software update may have removed your scanner from the supported models list. I will have to check that later to see if that is the case. In the meantime, here is a link to Canon's ICA driver package v4.0 which lists the CS9000F Mk II as a supported device and should get the device reappearing in Printers & Scanners.

Thanks for reply. I've tried what you suggested but still no joy. I also moved the USB cable from the hub it was connected to and attached it to the back of the mac.

Didn't make any difference I'm afraid. Am able to scan using the Canon software but would rather the OS.

If the ICA driver has installed correctly then if you open Image Capture, then you should connect to the CS9000F and be able to scan. Does this happen?

If it does then I'm not sure why its not appearing in Printers & Scanners, because when it does and you click on Open Scanner, the preview window that opens is basically the same interface used by Image Capture.

Thanks PAHU. It's now working. Opened Image Capture and message 'Scanner not connected' appeared. Clicked on File, 'reset Twain' and the scanner started. I said in my first post that I'd probably clicked on something I shouldn't have. It seems I was right. Not sure what it was though. Thanks again for your help and patience.
