I have a HP 840 C and I refill my cartridges from a company called Premier Cartridges ~ unfortunately they're based in South Wales UK (or my rep is and he may be a lone figure) His email is cartridges@xxxxxxxxxxxxxxxxxxxxxxxx He may be able to tell you of similar set ups, I don't know but you can always see what he knows. If its just the way you do it, I can tell you the way I've been shown just gimme a shout. Ange a.k.a.
