Summary: This printer goes through ink unbelievably fast. I print perhaps 2 pages per month that have any color at all on them, yet I need to replace all the color cartridges every other month. The black cartridge says it prints 600 pages, but barely prints 100 pages text (invoices) before it runs out. You can't print black and white if the color cartridges are empty. If you don't keep a barrel of ink on tap, you won't be able to keep up.
Summary: Purchased this printer earlier in the summer of 2013. This thing sucks down ink at an incredible rate and the cartridges are not refillable and very expensive. I've replaced the color cartridges twice and the black cartridge 3 times in 5 months at $64.99 for 3 color and $36.99 for 1 black. While I am pleased with the mechanical reliability of the printer, it is extremely expensive to run due to ink costs. I will be junking it as soon as the next cartridges run out.
Summary: I regret having bought this printer. The printing is fine, and the scanner is pleasingly quick, but the software and the user interface are clunky. You have to install the OCR software separately (you won't find out about this till you try to use it and discover it's not there), and while I've been able to do so on a PC, I have yet to succeed on my Mac.
Summary: I purchased this Lexmark Pro4000 in August. It was bigger than I expected (it's meant for small offices but I use it in my home) but it worked well for two weeks producing fine documents for an inkjet. During the third week, an error message appeared "Printhead Cannot Move" and the printer would not operate. I tried various options including clearing obstructions (none), rebooting, updating drivers, etc. to no avail.
Summary: Almost plug & play, reasonably easy setup. Prints crisp & clear, scan, fax, copy, send receive & wireless. Value & a good fit for my home network. Great support from LEXMARK, firmware upgrades, utilities & software.
Summary: I looked in Consumer Reports for their recommendation on the best printers out there. I have always had a Lexmark and this one was on the top of their list. I was not disappointed. Excellent printer and economical on ink. A great buy. A great price. And it arrived the next day!
