CANON MP730 ERROR MESSAGE 343 WASTE INK FULL

Question

Hi, I had the message waste ink near full for a while and I could get it to print but now the whole thing is jammed up. As far as I'm aware the error message 343 means waste ink tank is full!! I understand there is a routine to reset this issue and the ink pads may not be full. I don't mind if a bit of ink spills over, I would just like to get a bit more life out of the machine. I've seen some routines for other canon printers but not for the MP730. And Canon won't tell on their support line!! Any ideas
