Query: Spills ink inside the printer

I am all for saving a buck, so when I saw that the Rhinotek ink cartridges were cheaper than Canon, I immediately figured Canon was just overcharging. However, I do think there is a quality difference. When I opened my printer to check what cartridges I needed to buy, I noticed yellow ink in the gears and covering parts of the inside of my printer. My first thought was - this is a mess. My second thought was - Is this why I need to replace the cartridge already? I have no idea how much ink leaked out, but it should not happen at all. I had a Canon black cartridge, which seems to have outlived its Rhinotek color counterpart, even though I mostly print in black only. Given that Canon cartridges are marginally more expensive, I'll stick with them from now on. Sometimes saving a buck costs you more.
