I am in the US and can’t find replacement pads anywhere for my Canon G 3200 printer. I tried cleaning the small one, and it is a pain, but doable. One of the larger ones is decomposing a bit. I may try to rig my own replacement pads, but I also liked the suggestion to route the two overflow/waste tubes through holes drilled in the back panel, and affix catch jars. No more pad swelling/overflow, and one could even recover the ink and reload it. Very clever idea — I might try that. I am disgusted with the entire throwaway society, and Canon is super-guilty in perpetuating it, so it is up to us to outsmart them.
