First of all the positives about this scanner.1. It's fast. Very fast. Whether simplex or duplex.2. High quality scans.3. Easy to install.Now for the negatives:1. If the paper is not "fresh off the printer/copier" and in absolute PERFECT form, the ADF will jam EVERYTIME. Not only does it jam, it wads your original into a tight, crinkled up ball of paper.If the originals were stapled together...forget about it. You have to remove the staple, copy the first page, and then run it through this scanner.Although it is very fast (if you can get it to accept the originals), this is negated by the many trips to the copier to freshen up the first page.This is my biggest negative and the main reason for such a low rating.2. The ADF cannot auto-detect legal size documents. This makes it difficult to scan files that have a mixture of letter and legal.
