Re different or bad inks: I am careful to ask for the right ink, in this case for my canon ip4820. This same problem happened with the new magenta cartridge so I'm assuming it is simply a very clogged head. Anyone have thoughts (or experience) on this theory:The Hat said:SteveG
Question:- You said that you used island ink for years in Epson/Canon, Its not the same batch of ink by any chance.
The problems you are having with only the magenta sounds like a bad formulation,
bad batch or wrong ink and the print head obviously doesnt like it..
Also your refill ink may not be mixing very well with the OEM ink,
try purging the magenta cartridge and refilling it again..
Can print heads dry and clog in a dry/heated/hot room? I realize the printer should be used at least weekly but could lack of humidity result in print heads clogging? If so, would keeping a small dish of water or damp cloth inside the printer be helpful (when not used)?
