I'm running XP and MP210 is connected to PC by a Belkin USB cable. Printer works ok as does copier function, but when I try to open the scanner in any programme, I get 'cannot communicate with scanner' message. In device manager the icon has a yellow exclamation mark on it and properties window says 'windows cannot activate this device as its configuration in the registry is incomplete or damaged'. I've tried uninstalling and reinstalling software and drivers, as well as the printer in device manager, umpteen times. running a full scan with Registry Mechanic, or a Disk Scan does no good either.
