for those of us that do not want to give up the top fill method due to canon designing tight clearances on the newer printers, i am now using i little different adjustment. previously on the 560-640 and 990 printers i was cutting a slot in the upper case so the top of the cartridges could be seen during the entire travel of the print head thus there was no clearance issue, but any warranty was now void. even with the colored plugs there was some concern about clearance. the latest set of cartridges i am using i pulled the ball out of the factory fill hole and pushed a 9/64 drill through the hole to open it slightly because a rubber plug is too big to go through the oem hole, i then cut the top of a clear silicone (rubber) plug just below the lip and pushed the plug in until it was flush with the cartridge. it is a little tight pushing the plug in but if you open up the hole with a 5/32 drill which most suppliers tell you to use for the plugs i think there is a better chance you may push the plug all the through. the reason i am using the factory fill hole rather drilling a new hole next to it, is the cartridge is too thin and you may push the plug right through, the factory fill hole has, i will call it a short tube extending into the reservoir area which will support the plug, you then take a pin push it into the side of the plug to pull it out. this for the 220/221 cartridges that i am using
