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...
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
Summary: In the guide, Canon offered tech support by phone (I have a hearing problem), and by Email (I am low tech), but I think I will need an Owners Manual to refer to even if I succeed in getting it operational.
Pros: Quick Service. Package in good shape. Protective sheets and tapes looked intact. Contained a well written Set-Up Guide, Easy to follow up to the point of connecting to my PC where I was referred to the owners manual. There is a Setup CD-ROM which I will try tomorrow.
Cons: The box did look like it had been re-taped, and the setup guide and included items were easily accessable without removing the printer. The pictures of included items did not clearly show an owners manual (just printed matter).
