I use an HP all-in-one device as network attached printer/scanner/fax

Everything appears to work fine when I do a scan but the cover which was at the "top" (ie where I did not need to move the cropping bar downwards) becomes corrupt when I exit the scan application by hitting finish.  The other cover is fine.  The corruption appears to be a "shear" of the image to the right.

This is not a showstopper but it means I need to scan then reverse the cover art in the scanner and scan again, which is irritating.

Anybody else seen this?  More importantly, has anybody seen this and figured out how to fix it

The HP Scanner software is actually surprisingly capable.  It does cropping, rotating, resizing, colour correction and one or two other things (no sharpening, but I'm not a great lover of that effect anyway).

Still, making this post has had one benefit.  I started playing with the thing and I've found a workaround - I need to put the cover art in the bottom-left rather than bottom-right corner of the glass as viewed from the front of the scanner.

All very strange.  I'm guessing there is some sort of co-ordinate error when the image is handed from HP to the Profiler.

Anyway, thanks for your suggestions.
