Downgrading or reverting the firmware may allow your Epson printer to work with the previous version of your firmware before the firmware update occurred*. After you downgrade the printer to the previous version, you can continue to print with your compatible Epson cartridges. The following instructions work for Epson Expression XP-330, XP-340, XP-430, XP-434, XP-440, and XP-446 series printers. If you have a different Epson printer, you will need to find a different installer for your printer series in order to revert the firmware.
- Turn off the printer. While the printer is off, press and hold the “home” “power” “left arrow” and “cancel” buttons at the same time until the ROM menu appears on your printer’s display.
- Download and run the installer for the previous version of the firmware update
