Summary: The LCD screen failed, and Lexmark gave us an estimate of >$800 to repair it! I took a chance and ordered a replacement "operator panel" for $75 from Lake Erie Systems, and figured out how to replace it myself in 10 min. I got lucky, that was all it needed but Lexmark was no help at all. Their absolute lack of concern for their customers is probably industry standard, but I'll give another manufacturer a chance next time.
Summary: I bought this printer for work. It is less useful than a cheap laserjet. It takes forever to warm up to do a print job. It goes thru toner cartridges like a wino thru cheap wine -- it is NOT cheap on a per copy basis. And it is very cranky: when the toner cartridge is low, it not only warns you, it makes you jump thru hoops to get it to print anyway.
Summary: I've owned this printer for over a year and it prints fine. However, I bought it because I thought it would be economical over the long run. I am going from memory, but when I bought it I think the promotional material claimed 4,000 pages per black cartridge and overall cost 4 cents per page. My last few cartridges I got way less then 1,000 pages. At $100 per, that's 10 cents a page right there. Add in all the other toners and I conservatively estimate 15 cents a page.
Summary: I would give it a zero if I could. We have had it for 3 yrs and strictly used it for personal use, so not heavy at all. It has now started giving all kinds of error messages. I contacted Lexmark and have chatted online and they just keep telling me to try replacing this part and that part. I contacted a service center and they want $100 just to look at it and $95/hr to fix it! Not worth the money we paid and this is the second Lexmark that has fallen apart.
Summary: Cons: Very Loud, Excessive ReCalibration, Deteriorating print quality after few use, Inability to handle glossy paper, expensive replacements, Very low toner from manufacturer. Overall expensive product not worth it at all. Pros: features: network, built-in duplexing Overall feeling: Will stay away from lexmark from now on. There were cheaper products available but i vowed for a quality although expensive product. Turned out i was mistaken.
Pros: Nice clean copies unless black cartridge is low in which case a light gray cast covers all pages completely.
Cons: Gobbles toner even when not making copies: Copier calibrates (noisily) every 2 hours consuming all cartridges. Replaced all cartridges 6 months ago ($700); printed ONLY 75 copies since. Black cartridge is now low and color are half used up!
Cons: Fuser over heats after a couple of pages turning them gray. Not even close to the published duty cycle of 30,000 pages. I ran only 20,000 total pages and had to replace fusers and rollers several times. I ended up buying another printer.
