Summary: I've owned this unit for 21 months, and I'm giving it away. At 1600 pages, it started giving "out of toner" messages, even though the toner cartridges all had plenty of toner remaining. Apparently it's a timer or some such that causes the warning. Eventually, the prints started coming out in reduced color (faded), still with plenty of toner left. Finally, the prints started getting blue spots.
Summary: I have had this printer for over a year and I have to say that overall, I have been disappointed. The print quality is adequate, but overall the unit just does not perform up to the standards of its major competitors. My two main complaints are: 1. The unit jams a lot. At first it seemed okay, but now it jams with nearly every job sent. Given that we have only printed 2679 pages total, this seems excessive.
