@@RefreshCartridges Thank you for this information. I was wondering if both cartridges have the same capacity but that the regular cartridge is just filled with less ink.
You can inject ink directly into the sponge and re-glue the lid, but this is far from ideal. We have a video on this topic that allows refilling without removing the lid. I would recommend searching for " How to Refill Canon CL-546 (8289B004) Colour Ink Cartridge".
