Review on MYCARTRIDGE Remanufactured Ink Cartridges Replacement for Epson 802 802XL - Compatible with Workforce Pro EC-4040 EC-4020 WF-4740 WF-4720 EC-4030 WF-4730 WF-4734 - Black Cyan Magenta Yellow, 4-Pack by Flavio Iyer

After installing these remanufactured cartridges my printer does not print and reports a service error, cannot recognize the ink cartridge. I can't disable this error message and overwrite the error. With the same success, you can spend money and buy official Epson cartridges. Of course I didn't keep the packaging, so I can't return it.
