Summary: The one I received has been a good one so far. from looking at the reviews it looks like all consumer electronics are subject to at least a certain percentage that just don't work out of the box, but this one is ok and the duplex feature works pretty good although it does need a reboot once in a while because the control panel locks up on occasion.
Excerpt: This printer installs easily out of the box and has an easy to navigate setup menu built in to the on-board screen. Even making changes in configurations is no problem later. It prints quickly and smoothly. We have 3 of these in our offices. We also added the 500 sheet try for extra capacity. Bammm!
