We have a Canon InkJet PIXMA iP4000 printer. As the ink cartridge is expensive, we buy the colours & fill the cartridge up. It worked all the time fine until the last time, where a lot of magenta ink is inside the printer after the procedure. The photo prints have all a strong magenta touch & are useless.
My question is how one can clean the printer from this spill of colour without damaging the hardware?
