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!
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.
Summary: First off the design of this printer is nice, it looks like a piece of art, too bad it's a piece of junk... The cons: this is the second Canon I've owned in two years, Canon printers tend to permanently clog if you don't use them for a couple of weeks and there is no way to clean them if they get to...
Summary: Programs that will print in black & white only have a problem with this printer. The printer default is color. I have Presto Forms and it will not work with this printer because the program scans and prints in black & white. Canon cannot advise me how to change the defaults to black and whit.
Duplex Clip causing Paper Jam Issue MX510 and MX512
8 October 2013
Summary: This printer is ok for the money but after 6 months usage the duplex function stopped working altogether. My Epson never had this issue, or previous Canon Models. We started having problems of printer jams constantly, so I thought to open up the back of the printer.
Conclusion: I bought this printer to replace a previous Canon I had for 8 years. I've had three issues with it. 1. Paper falls on the floor, even when the tray is extended. Very poor engineering design. 2. There is a huge lag when printing wirelessly.
Cons: Slow Print Speed, unreliable, long lag with wireless printing
