wf4740 is not supported not sure we will develop firmware for this model in future

1. I dont have it 2. You dont need it - just make the same steps next time 3. Disable automatic updates

If your printer has updated from internet - you have to do following: Upload to printer our firmware in regular mode Don't put printer in firmware mode Then restart printer

Please reply on my 2 questions

P.S. We can give You little discount. But We have NO free keys

So I paid for nothing! Did You used your Key??? If You have not used - You can use it !!! If You have used already - You have paid for using this key on your printer and key did its job - printer became chipless. Activation Key doesnt garantee Your printer will not have any problems. So if You have used the key - it means You have paid for using this key and for making your printer chipless. Chipless firmware doesnt have any relation to other printer problems that can be in future. P.S. We can give You little discount. But We have NO free keys

You have already used Your Activation Key You have paid for key and got the key. Then You have USED Your Key. Every key is generated after payment. We have no free keys. If You have other printer - You have other key. For the printer in which key was used - it can work as many times as you want. So the kry you have purchased - is valid on printer that was used for chipless.

But for 2-nd, 3-rd etc other printers You have to use other Activation Key. You want to buy 1 key and use it for 1000 printers?? ????

You can not use the same key on more then 1 printer Key is for ONE device

What firmware version have You uploaded to your Printer??? Have You disabled automatic firmware updates from internet?? Maybe Your printer had updated from epson again?

Download new updated firmware - FWF469TL_CL30J5_WF3720.zip

You can see list of supported printers for chipless firmware here - https://chiplesssolutions.com/support.shtml

Activation Keys have 1-2 months expiration date After that - keys are removed from database

After keys expired - they are removed from database automatically

Create text file and input recovery code in it. You can not paste code to folder. Only in text file. Disable Automatic Updates first!!! If for some reason you need to recover chipless firmware - just upload firmware in regular mode and activate by your key once more time.
