Summary: The scanner does beautiful work! The only thing I can complain about is the TMA adapter. I can't figure out how they want you to use it.. I found it very difficult to use for scanning slides. There probably is a way to use it; so I will have to call HP to find out how to use it. In the mean time I am using a TMA from my last HP scanner for slides. If you don't have an old TMA adapter, it is a big deal if you want to scan slides.
Summary: Our unit has been used in a healthcare office for the last two years or so. Easy to instal and has proven to be a real workhorse. Never a problem. A bit noisy but nothing to keep me from purchasing again.
