I have a windows 7 64 pro machine that for some reason no longer works with a brother all in one printer/scanner, when I try to scan. This happened seemingly out of nowhere.

Printing still works. When I try to scan from photoshop, photoshop crashes. When I try to scan from device manager (which takes a really long time to access the printer) I get an error saying: "operation could not be completed. (error 0x00000015). the device is not ready.

I tried uninstalling/reinstalling the printer and drivers. I have also run the brother driver cleaner and then reinstalled and get the same results every time.

I had access to another HP all in one. And very strangely When I setup this new printer I have a similar issue that happens. I am able to print but when I try to scan from the HP tool nothing pops up.

So my thoughts are it is something to do with the twain driver? But I don't know what to do or check. Any help is appreciated.
