Quote - I'm using the Epson Stylus CX7000 Fax/Scanner/Copier/Printer and it prints just fine if one cartridge is empty. It nags the hell out of you but it prints.

I wish I had taken a closer look before I bought my home unit.  I was in a hurry and just grabbed one off the shelf after my old one gave up the ghost.  But, I am happy with it.. when it has full ink.
