I am interested in chipless firmware for this machine also. What is the hold up?

Hello, I tried a firmware downgrade instead of disabled ink firmware (that bricked my previous printer), the process went through without errors, printer restarted but no firmware downgrade was made. Printer still has factory firmware, which is DG03K7 - 03/07/2020. Can someone help me here? I've already spent $40 trying to make my printer chipless with no luck. FYI, my orders were #24072262 and #24789104. Thank you!

SOME NEWS ABOUT WF-3820 CHIPLESS

On the last screenshot printer is available via Wi-Fi only which means that WIC does not see USB connection either, futhermore the ports tab in the printer's properties window will show the port even if the printer itself is offline. Please, show how printer's port is recognized in the windows device manager or in the usb view (microsoft tool for usb enumeration available online).

AFAIK, you will need to update to official EPSON firmware for the printer to recognize new maintenance box and then, when installing chipless firmware again, it will ask you for a new key. So you only need one new key. You will need one key each time you want to upload chipless firmware to the printer.

Still no chipless firmware on this model? Its been 2 years of waiting. Thanks

Good day. Can you contact me directly, I will send contacts in PM.

I would also like to express interest in chipless firmware for the WF-3820

wf7820/7840 also in an Epson EC-C7000? Yes

Maybe in this year

According to the screenshot printer is connected via Wi-Fi only, if you had USB cable connected at this time then either USB module is disabled or not working properly. Silly question, but you are using USB port at the back of the printer and not in the front, right?

Good day, each time when you connect usb printer to the PC virtual printing USB port name (USB001,USB002,etc) is assigned, once you install the driver this assignment is remembered and as result the more installed printers you have in the system the higher is port number for the next one. Unfortunately, license.exe can only work with first 32 ports, so in order to use it with the new device, you need to delete one of the existed printers with low port number, freeing it, and then replug the new one (of course it will only work if new device is not installed itself, otherwise it will have fixed port number and nothing will change). Bottom line, remove as much unused printers from the system as possible.

We will add this model and let You know
