Please download new firmware version here - http://chiplesssolutions.com/download/WF3720_FWF469TL_ZZ99Z9.zip Upload firmware to printer in normal mode - dont put printer in Program Update mode.

Now power on the printer - chipless firmware is installed now in your printer! Please reply about results. Share this post Link to post Share on other sites

xemoterp 0 Report post Posted February 9 The above license file fixed my issue completely. I am now able to use my Epson WF-3730 with an ink cartridge that was originally not accepted by the printer (a brand new 3rd party one that had a chip that was incompatible with the printer). The activation procedure was exactly as described (easy) with this new license file application! Great customer service and a fantastic solution to using 3rd party inks with the Epson WF-3730!
