Customer Review: Fast, but autofeed isn't up to it
I was previously using the HP7650 and had a positive experience. I am a CPA and was looking for a faster solution to scanning workpapers. The N7710 appeared to be a solution. However, I should have done my homework. The HP drivers are not compatible with Windows Home Server software so I couldn't use my server as a scan server. Additionally, the autofeed is very unreliable and inconsistent.
