Be sure Your printer can be modified to Chipless Version.
That means You can pass Step 4 of this guide.
Don't buy Activation Key BEFORE You have checked if Your printers Firmware can be changed to Chipless! Follow next 5 Steps.
Step 1
Download and extract Zip archive (How to unzip (extract) files from Zip archive?) with Epson WF-4720, WF-4730, WF-4733, WF-4734, PX-M780F Firmware  - CM27J5 version
Step 2
Connect printer to PC (under Windows OS) by proper USB cable.
Disable all Epson processes and services. You can do this manually using task manager and administration tools or You can do this via WIC Reset Utility (install and run it, then select MENU -> Support -> Disable processes).
Step 3
Upload Firmware to printer in the NORMAL MODE (do NOT use service mode yet just start the printer with the power button). Run EPFWUPD.EXE file and follow all steps until Firmware will upload in printer.Â
When Firmware Update process is complete - printer will restart - usually it will take only a few minutes but can continue for 10-20 minutes in some rare cases.Â
If process hangs or stops at 80-99% - replug power cable and start printer manually.
Step 4
Now check current firmware version ( how to check).
If firmware version is
