Summary: I have had this printer for nearly two years now and they are still selling the exact model I have. The printer itself prints very well and I have rarely had any problems with either print quality or jamming. I use the unit moderately, so the print cartridge life has not been an issue. However, I run my printer on a network and it is physically too far away to plug in with USB. I've run into a few problems: 1.
Summary: After comparing multiple All-in-One color laser printers, this one had the best features and decent customer reviews online. One thing to note when purchasing online is the weight. 85 lbs!! This thing is a beast! After letting it do its configurations and setup, everything installed fine. A wireless feature would have been nice but in my case isn't necessary, I just ran another wire from the hub.
Summary: In a small office without servers, the MF8530's quality, speed, and silence might make it the perfect fit, but beware the price of toner per page. There are some nice features - it particularly sells itself on the basis of only taking a couple of seconds from cold to print - but for me those are outweighed by the negatives. I'm not a fan of older Canon multifunctions, and this reinforces that impression, though I was really hoping they'd improved.
Summary: UPDATE 2014: This printer is now too obsolete for me to recommend buying it new. Maybe makes sense to grab it used for a good price, but the canon cartridges are way too expensive so you'll still be paying too much unless you risk using off-brand cartridges (I've never tried... was too afraid to damage my expensive printer). I owned it for three full years (Jan 2010 to Dec 2013), and it worked like a charm during that time. The quality and reliability are great.
