anyone know anyting about refillable cartridges?
bought a set that came prefilled, all worked fine. except now i've refilled the black ones they don't want to pull ink through.
the cartridge has a fill hole and a breather hole, i've followed instructions. no joy at all.
its not a print head issue i'm fairly sure as i did get them to work for a few prints after pushing the cartridges down really hard.
am i doing something really stupidly wrong?
