I'm running into folk that are upset over replacing ink cartridges. It doesn't really matter why it doesn't switch but if that's a DESIGN FLAW in your view, call up and ask for a refund then start your research into printers and be sure that this feature is on your list.

Hopefully a new cartridge will let you print.

There are reasons that a printer will not drain cartridges absolutely dry. Think carefully why.
