Buyer Beware

I purchased this scanner to scan 2 sided documents for financial record keeping. What a mistake. Forget the speed listed in the marketing specs. If you use the ADF, expect 112-179 seconds per side at 600 DPI. Then, all the images appear very light. I tried all the software included in the package and the only way to fix the light/dark issue is when you use the push buttons on the face of the scanner. Then on top of the 112 seconds, you get to wait for the application to open and data to be passed to the application. For this job, pay less with the Fujitsu fi-5150 and be much happier. I swore I would never buy another HP scanner 4 years ago. I wish I had stuck by my decision. Now I have to pay to send it back and re-stock fees. Don't make the same mistake.
