Summary: This printer is NOT compatible with Windows 7. When I used it with Windows XP it worked like a charm but it's been nothing but a nightmare since I had to upgrade to Windows 7. The function buttons on the printer are no longer usable. I have to open up the printer in my computer every time and set the scan from the computer. The feeder works about 20% of the time.
Conclusion: I got this printer for Christmas 2012. It worked good until about a month or so ago. I went to scan something for school, and the printer wouldn't scan. There was a pop up saying there was a document in ADF. I swear to you, there was no document in the entire printer. I am not allowed to do anything on the printer until this alert is gone.
Summary: This is my second mx512 with the exact same issue. Will not stay connected to my wireless network. It is located about 1 foot from my router so it's not a signal issue. My router is an ASUS RT-AC66U and all my other devices connect and stay connected rock solid! Going to put this thing on Craigs list and be done with it..
Conclusion: I purchased this printer to replace an OLD thermal fax machine. I've been quite pleased with it so far. The "fit-to-page" feature of the copier has been a great help with documents that are printed way to small. Also using it to scan documents that need to be saved, but don't have to be in paper form. The print quality and speed are excellent for an ink jet printer. The wireless works flawlessly which helps as I don't have space for it near my computer.
