Firmware updates are released mostly to fix firmware bugs, crashes or issues to improve a printer's performance. However, this is not the case if you are using a remanufactured or third party ink cartridges.

Aside from fixing printer issues, firmware updates are also designed by printer industries to limit the use of third party ink cartridges. If you are currently using or planning to use remanufactured inks, then we strongly advise you to 'NOT' update your printer's firmware to the latest version. Please note that once your firmware has been updated, your printer will only accept OEM or original ink cartridges unless you will perform an Epson printer firmware downgrade or reset it back to its default settings.

How would I know if my printer's firmware has been updated?

Printer industries can automatically update your printer's firmware without you knowing especially if it is connected to your Wi-Fi or through a cable that is connected directly to your computer with an internet connection.

If you are getting an error messages such as 'Cartridge is missing or damaged.', 'Remove and reinstall ink cartridge.', 'Cartridge not being recognized.' or if the ink cartridges suddenly stopped working when it was working perfectly fine the first time, it means that you might be one of those who are affected by the firmware update. But no worries as you can still have your printer to accept remanufactured ink cartridges by doing an Epson printer firmware reset or downgrade which will be discussed later in this page.
