Hello, I am Christina Pine. I am a printer offline executive and freelancer. If your Epson ink cartridge keeps saying that it is empty even after you replace it, you will need to reset it. You can only utilize the "empty" cartridge's remaining ink if you reset the Epson ink cartridge because it often contains some ink. Take the printer's print cartridge out. Match the reset tool's base markings with the cartridge. Press the reset tool pins firmly on the cartridge's chip contacts for a number of seconds. When a red light is blinking, the cartridge and the gadget are firmly in touch. If a blinking green LED light appears, the cartridge has been reset.
