I know you're looking to do the duplexing thing but I have similar types of docs to copy as you and wanted to see how my multifunct HP would handle it. I put 10 loose sheets into the copy tray and had it scan to a pdf file. It ran all sheets thru automatically and, after post processing, created about a 2.5MB file. Took all of 10 minutes, most of which was me just fiddling with the software. I scanned text with line dwgs @ 200dpi, gray scale. Cool.
