Terrific workhorse pronter, better than the M610dn since this version the M611dn can use the X and Y higher yield toner cartridges, has the higher duty cycle at 275,000, great machine and synced for wireless printing from an Iphone or Droid.
I bought this printer thinking that it would be a workhorse but instead it turned out to be a complete dud! It malfunctioned within a couple of days after I installed it…good luck getting in the phone with someone who can help you. I would find a different model or brand.
Printer printed 3 pages before malfunctioning. HP sent a tech to fix and he needs other parts to fix. The printer does not work and waiting for a fix from HP. I don't know why they are not replacing the faulty printer!
We run a small print shop with several enterprise level printers, and have been using the old M602s, which we have loved, but they are finally giving up the ghost. We replaced 2 of them with M611s, and could not be more pleased with their performance. SUPER FAST. We've been using them for 2 months now with no complaints. Plan to buy 2 more this summer as funds permit.
Received printer and within a week it was printing super faded jobs. Did 2 hours worth of technical support and had to return it and get a replacement. It's unfortunate, but maybe the new one will be better.
