I have a 1505/6400 laptop and an AIO Photo 944 printer that have always worked well together. The last time I tryed to SCAN, the normal 'popup' screen did not appear on my computer screen asking what I wanted to do. A message appeared on the printer screen saying...."Dell Photo AIO 944 printer driver not responding........please make sure the software is installed" I uninstalled and reinstalled the software but that made no difference. I CAN print from the computer.

 

Any help would be greatly appreciated. Thank you !
