I've been buying my EPSON C60 ink cartriges by PrintPall for over a year. They are not EPSON original but they work fine and are much less expensive than EPSON ones. This time I've replaced the black ink cartridge following the usual procedure (at least .. I hope so as I do that automatically) but when I push the button that should cause the printer to start loading the ink then the printer starts moving the head but then stops right away. The ink indicator shows that there is no black ink at all. I've already tried to turn Off/On the printer, unplug/re-plug the USB cable, shut-down and reboot my computer ... and got nowhere ! May the cartridge be defective ? Or I might have touched unadvertently the back circuit which is strongly discouraged ? Can the printer internal cicuit/program be messed up ? I tried to reset the printer by MTINK .. It resets but it still refuses to load the ink .. I've ordeed a new black ink cartridge.....hoping the current one is somehow defective ... Any other suggestion ? Thank you. Maura
