I have a Windows 7 Professional x64 machine that 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, but when I try to scan from Photoshop, Photoshop crashes. When I try to scan from Devices and Printers (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. When I set up this new printer I had a similar issue that happened. I was able to print, but when I tried to scan from the HP tool, nothing pops up.

What's going on here? Is it something with the TWAIN driver? Any help is appreciated.

Figured it out. It was the Windows imaging aquisition (WIA) service that kept stopping.

After running sfc /scannow

from command prompt as admin all is well.
