I have now spent many hours trying to get answers to my one simple question. Canon has extorted my personal info from me, just trying to get help with this one simple problem. I've been forced to register my info with canon and go through all my walmart purchases, back through May! The paper manual for this PIXMA TS3522 includes ZERO specs re: ink cartridge replacement requirements. I am now forced to eat the $30.00 I spent on cartridges numbered 243 and 244, when the only compatible cartridges are numbered "275 and 276". BEWARE Friends! If just getting info on something as basic as ink, is THIS time consuming and frustrating, I am going to avoid canon as much as possible. SHAME!
