printer displays 6A81 error as soon as it is turned on.  have checked several times to make sure there are no paper jams, foreign objects/debris, blown interior out w. compressed air, checked/cleaned  purge unit pads/wipers, and checked to make sure ...
does Canon currently make an AIO printer w. rear or top paper feed AND both wireless and USB connectivity?  i'm looking for a replacement for my Pixma MG5320 which had both but (UNFORTUNATELY!!) is no longer manufactured.
