office scanner

[qweds]

hi,

i've been asked to help find my office a new scanner. it has to be an autofeeder with high speed turnover so as to do fairly large jobs quickly. (min resolution 1200 X 2400, dmax min 3.2) it will be used primarily for text and need to be highly reliable, most of the people using it are not terribly tech savvy.

any recomendations? I'm reading all the relevant review i can find but nothing is quite as good as first had experience.

thanks
