Summary: Comments about Lexmark C530DN: This printer has a driver that allows you to specify where to source the print material from such as Multi-purpose feeder or maintray, and also the paper type which is required to avoid jamming for thicker paper stock. This printer doesn't read the instructions in these menus, consequently the only way to change tray type and paper stock is to manually make the changes on the printer itself which makes the printer useless in a conventional...
Summary: I have owned this printer for all of 3500 pages, 95% of them normal text on normal paper. In that time I have gone through *2* black cartridges (nominally rated for 4000 pages EACH), and these suckers, at $100 or so, are NOT cheap. I also own a Dell 3100CN, and whatever its other faults, printing the same load it gets 30% MORE than the nominal capacity. My Dell may cost a penny or two per page. The Lexmark is a hefty multiple. Otherwise, it is a superb printer.
Summary: I was attracted to the Lexmark by the cost. However, you get what you pay for. After printing anything over about 6 pages, after the job finishes, a very loud fan turns on in the back of the printer, and stays on for 6 minutes! I called Lexmark, and they said this was normal! If you want a quiet printer, avoid this printer.
Summary: This printer uses toner every day, even when you're not printing; it "calibrates" itself, moving toner from the cartridges to a toner receptacle that you have to pay to replace in addition to those empty toner cartridges. If you leave the printer turned off, it will calibrate when you turn it on, and/or sometimes when you first print; it takes a minute or two, so you can't rely on this printer if you are in a hurry.
Pros: quiet; reasonable print quality
Cons: uses toner constantly; slow to print first page
