Summary: Scans photos and documents fairly well. Film and slide scanning dificult at best. The instructions are very poor giving only the very basic directions for use with no help in using any of the advanced functions. On line help is not much better. Would not buy another unit.

Summary: Updated: I can't believe it's been a year. I have learned to work work the software- and I am realizing that it seems to have been designed, essentially, to scan photos without a whole lot of effort, which it seems to do pretty well. Once I learned how to set it up for this- and actually had a need for this- it began to make a little more sense. But not much else has changed, and look forward to upgrading to something a little - no, make that a lot- better thought out.
Summary: I have approximately 10,000 slides to scan. I purchased the 4850 and after about 3,000 slides began to get three to four dark blue lines across the image. After reporting it to HP they sent me a replacement TMA. The new TMA worked fine for the first 450 slides and then BINGO, I now am getting two dark blue lines again. I think the machine is not engineered to handle the work load I have.
