Summary: This is as bad a printer as anything I ever have bought from HP (the worst up until now). The glitchy software has a mind of its own, when it isn't just holding the printing until some random time has elapsed (up to 20 minutes),it is refusing to fax at all, the scanner sends the data to files but it is corrupted and losing drivers every other week.
Summary: Don't buy these, they are junk. I work at a government agency that uses these printers for small workgroups. The last 2 we received were out of box failures, would not detect paper in the paper tray. They are noisier than the original MX310's when they do work. Buy at your own risk, these things are GARBAGE!!!
ADF Roller problems and Fax forwarding to FTP silently dies

Summary: I now have a sample size of two of these in two separate locations, both purchased because they (as with an older larger model at another customer) can easily be set up to forward received faxes to an FTP server instead of printing them. I do not expect to purchase any more of these unless a new firmware (they're both on current P454/511 as of 1/26/2015) fixes the FTP problems.
Very good printer/scanner/fax, expensive toner but there is a work-around.

Summary: Overall a very reliable machine. Lexmark support is very good. We were initially having issues with scanning to our 2012 Server and contacted Lexmark and they provided us a beta firmware (which as of October 2014 is now public) and that resolved the problem. We have 4 of these in our office. Some have 100,000+ pages on them and have had the imaging unit replaced, which is fairly inexpensive compared to the toner... The toner is the worst part of this printer.

Summary: A fantastic machine with built in duplex & Airprint capable for all IOS products. I've only owned it for a short time but so far it is a great machine. I'm not technology savvy by any means but setup was a breeze. Scanning takes a little getting used to but works very well. Finally we can print from all our IOS devices with no setup requirement except connection to our home network.
Summary: I bought this printer MX310dn to use on my office network. The specs said Network...The instructions say PURCHASE a network adapter for the printer. I SAY I trip to costco to return the pig in a poke.
