replace the cartridge............ all printers do this, what did you expect? it will run with no ink?
Epson forces you to replace ink after X number of prints, regardless of ink levels. So if you print a few hundred pages with one letter on each page, it will force you to replace the ink even though you have near 100% ink. It will refuse
to let you print until you buy another ink cartridge.
Additionally as infuriating, if it decides you're out of color, it will refuse
to let you print anything, even if you have 100% black ink.
These are terrible printers. Nobody should ever buy an Epson
