Panny Printer/Scanner WIA issue; can't scan in W10, ok in W7

Well after having little if any in W7 O/S for a Panny KB-MB271 Multi Function Printer/Scanner, the Scanner function is dead in W10

Now after checking using a slightly newer version of the software/driver (V123 vs v122) the missing WIA service is now showing in Services which it did not show before. BUT, the scanning function still doesn't respond. (Printing is AOK).

It shows stopped, the auto function is set to 'Auto Start Trigger'. I tried to change the Start Type, but anything else errors out. I can manually start it, but it drops back to stopped apparently when I try to do a scan.

There is no newer driver version than v123 listed for W8 from Panny..

Why and what was changed in 10 from W7 other than breaking another working function from one O/S to another as usual???
