We have this at work, with 2 paper trays and built in network card. Works OK, but is loud and fairly slow, in my opinion. If it gets two different types of print jobs, such as a basic letter followed by an envelope, it takes a good 5-10 sec to figure itself out between pages. Pretty quick if it is just page after page though. Color quality is pretty good for a laser, but not as good as a top notch photo printer, like the Canon S820/i950. And it is loud. I can here it clear across the office sometimes when it is clacking away. The toner is in a rotating drum, so you can replace individual colors as needed. It does take several minutes to get ready after a toner change. We do more B/W printing than color here, but it has been doing pretty good in the 2 months we have had it.
