That sounds rather like Epson with separate heads/carts. Got so tired
of trying to revitalise those that I swore off Epson completely.

Still have an olde HP900 series inker that seems to fire up fine about
every six months, and a Canon that rattles/clunks/whirrs for about 90
seconds at every power-up. Good thing nearly all our printing needs
are mono and met elegantly/economically with an HP Laser.
