"Useable but some problems"2.5 starson by patpending
Pros: Good price, compact, network built-in
Cons: manual sheets feed crooked, draws over 400 watts
Summary: I bought this multi-function to replace separate HP Laserjet 5P, ScanJet, and HP Fax. The 7820N works well receiving and sending FAXs and is equal in quality to my old 5P for printing. The scanner, however, does not produce sharp, crisp scans, but is adequate for scanning documents. Network set-up was simple. However, if you swap out an old 7820N for a new one you will have to completely repeat the set-up (you can't just unplug from the network and plug in the new printer)
The 7820N is a power hog at start-up (draws more than 400 watts). It kept tripping my computer's battery backup until I plugged it into another circuit.
The most disappointing part of this product is the manual sheet feed. The guides will not feed the paper straight. This makes it impossible to print checks or any other document that requires accurate registration.
