Thank you for that tip Terry, but things have had to move on and I bought a new MFP last Sunday. In any case, the HP scanner was a very last resort, because it had a cloudy glass platen, a manufacturing fault by HP's own admission but which they would not budge over because it was 4 years before I found out. It had to be cleaned all the time to get good scans and was a nuisance in an otherwise good machine. Makers can be devious and in that case HP were.

I might just try it when I have more free time, but right now I'm too busy going to relatives' funerals, it's one of the hazards of old age! Happy computing.
