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.
Conclusion: this product is unacceptable. I spent 2 days to install the software for the scanner. the software is a mess...no help from on-line manual. box has missing parts.,AND i got a broken cd scanning takes more steps & needs the same answers over & over...user specifications you have entered as defaults don't take,,, even if the sw was good, this printer is SLOW there is a long wait before you can start to scan.... takes 3 minutes to scan 1 page..
Conclusion: I was very proud of this purchase for the first 14 months of use. Then I had one paper jam which happened in the back and I had to open the back of the printer to extract the paper. And from then on, the alignment was off. I tried multiple auto corrects, and multiple manual corrects. Neither worked. SOOO FRUSTRATED, I could throw it off a cliff and feel much better.
