Firmware patches are used if the performance of the printer has to be fixed with firmware glitches, crashes or problems. In order to restrict the use of third-party ink cartrids, the firmware is structured in addition to solving the problems in printers. It's highly recommended that you should not upgrade your printer firmware to the new edition while you actually use or expect to use used inks. Recall that your printer can only allow OEM ink cartridges by the time you reset or reset your Epson printer firmware to default settings when the firmware is modified.
