Yes I have tried exactly that in that order many times, I have done it with many other printers. The issue should be somewhere else, don't you have any updated firmware for this model?

Yes it was succesfully activated but chipless is not working, printer still shows no ink and can not print or copy.

I already told you this is my key BD62Q-9KMQX-R494P-TD9X8-3TVQT , I purchased it from a reseller, hope that's not a problem, I suppose you can verify the key is valid. If I have to purchase another key tell me, but I want to know if it will work. (Firmware loaded and activated to my printer is the one from https://chiplesssolutions.com/download.shtml)

Right now (after doing procedure I told you before) this appears when enter to firmware mode: Note: I also tried to upload chipless firmware in this mode, transfer 100 successfull, but still after activating with license it shows not recognize ink

@John_Admin thank you for your answer I hope you can Help me, Wic reset do not work with this C869R, firmware version: Printer: I do not know order number, but this is key that was successfully activated: BD62Q-9KMQX-R494P-TD9X8-3TVQT

Hello, I successfully loaded this chiples firmware (in normal mode), then I successfully activated it with purchased key. The issue is that after power off and then power on printer (without disconnecting) printer still shows not ink detected, chipless is not working despite firmware is loaded and activated. I need help please

I am thinking to try using "WF-4740 (EURO) Epson adjustment program" to initialize printer(USA WF-4740), then test if can recognize EU WF-4740 ARC chip (T35XL)

@John_Admin Could we donate $ for WF-4740 Chipless solution development?

I found out that lastest chipless firmware (XP230_FWE857TL_FO30HA_FO99Z9) is detected by Epson software updater as an older firmware version. It shows Epson software updater This happens when printer is connected by wifi. Firmware and chipless functions work correctly

Thank you. It works as expected with your new chipless firmware MZ99Z9

Please I need help

This is normal mode. Current official firmware installed on printer is newer than chipless firmware, is that the problem?

I got a XP-2101 . Current firmware if official MZ21K2 . It can not receibe chipless firmware MZ01JA

Hello, I want to know if there is any news on development chipless solution for WF-4740 ?

After installing chipless firmware everything works, except that printers does not respond when doing a print head cleaning from epson utility. Same thing happened in 2 different printers, same XP-2101
