HP Printer/Scanner - There is no TWAIN-compliant Device installed

The Black Oil

I'm getting this message when I try to use the scanner on a HP CM2320n.

All was fine a month ago, I scanned a single page. I didn't need to use it for another week. Came in, turned it on...and no joy with the scanner. I need to scan another page now and can't. I'm using a Windows 7 64bit HP desktop.

I've been around the block - uninstalled/reinstalled many times, without success. No matter what I do, only plug in the USB cable at the appropriate time, turn off certain things in services.msc, etc.

I've tried HP by phone and online chat. Even they've given up and have sent me a quote for €200 to sort it out. One of their solutions is to "try another computer", well, I can't because we don't have a spare one in the office and I can't ask a colleague as it takes quite a while to uninstall/reintsall. All that's working is the printer side, the software, when it was fully working, showed the full details of the printer in Device and Printers. There was a 'scan a document option'. Now it only recognises it as a printer. The start menu in Windows does have a scan option, but when I try that I get error - There is no TWAIN-compliant Device installed.

I've read advice on HP's forums, but am not having any luck.

Any ideas?

Are you the only one connected to the machine or is it on a network?

Have you tried downloading the latest driver from hp?

It's standalone, USB only - not networked.

The driver I have is - HP Color LaserJet CM2320 MFP Series Full Solution, as recommended per the link. It's what I've been trying all along and did work originally, but now won't play ball.

Does it scan if you initiate it from the control panel on the printer itself?

The Black Oil

No, in doing that it says waiting for PC...

Might be of some help

I tried some of the steps on that link, services.msc, etc. No joy, unfortunately.

I uninstalled/reinstalled the software again, but it just won't take the scanning aspect of the driver, for whatever reason. The HP Print and Scan Doctor wasn't much help.

Below is what I see at the moment.
