CANON I Fix It? | MG5750 Printer That Doesn't Recognise INK!

This Canon Pixma Printer refuses to accept the yellow ink (error code 1684). Initially, I thought it was just going to be a case of cleaning the cartridge contacts... but it turns out, I was wrong (for a change!) Let's see if we can FIX It?! Hope you enjoy! Steve PS. I'm not an expert in repairs at all. I do this for fun, and it may not be the best or safest way to go about repairing broken stuff. I'm pretty good at melting plastic though. Please don't copy me - I'm an idiot.
