I have a HP LaserJet M1217 ncf MPF - Product number CE844A


I was running Windows Vista when I initially installed it.  I have subsequently installed and Run Windows 7.  The Printer has worked perfectly, but today i went to scan a document using ReadIris and I get "Cannot open the Twain default source".


So I have bought the upgrade to ReadIris (not necessary I now realize!!!) and I have down loaded the Drivers from the HP site for the M1217 and have restarted the laptop and when I went to scan the document what do i get but 

"Cannot open teh Twain default source"  Argggh after an afternoons work no further!!!! Anybody any ideas?

Re: m1217

Hi 18987,


If I here you correctly, you upgraded your Windows Vista PC to Windows 7.   Which WIndows 7 version?
