RE: Canon MP210. I bought a new Canon 51 ink cartridge. Although the info with the printer calls for a 31 or 41 cartridge, I understand that 31, 41 and 51 are all kissing cousins with the only difference being the amount of ink a cartridge holds. The MP210 will not recognize the 51 cartridge although it fits correctly. Is there a way one can circumvent the system and get the 51 cartridge to work?
