ive got a epson printer 415 and all the inks are fine ecept megenta and ive replaced it with anothher one to see if that makes eny difference and it dont so can eny one help
Did you go for a while without printing? That particular printhead may be clogged with dried up ink, as the printheads are in the machine and not the cartridge on that particular printer. Does the printer recognize the cartridge or not?
