Sjane 0 Report post Posted November 16, 2021 Hi I have been updating the Epson WF2850s for a while now with no issues, did a printer yesterday and all,was ok. Today I tried to activate the key for 2 different printers and the progress bar goes all the way across,but no confirmation or even an error will show, it then doesn’t give me a recovery code. I reinstalled the license.exe file (I noticed a new download versions so tried both) and for the keys I purchased today all of these are doing the same thing (I’m hoping I didn’t ruin the 5 keys I purchased by trying them), just no confirmation or recovery code. I then tried to use a key I know I have redeemed and I get the error telling me that it can’t be activated as I would have expected.Any ideas? I have done these all the same way, never had any issues. I have also restarted the computer, unplugged the printers, re did the firmware in case it hadn’t loaded, swapped USB port and cord, checked the computer internet protections wasn’t conflicting as well. I have another 5 printers I need to add the keys to in the next day or so so now I’m stressing. thank you Share this post Link to post Share on other sites
John_Admin 388 Report post Posted November 16, 2021 How to use Recovery Code to recover chipless firmware after updating from Epson server: If you have already activated printer in the past and then accidentally updated the firmware then you need to use recovery code that you saved during activation process to restore chipless functionality: Connect the printer and start license.exe again. Select your printer in the dropbox and paste recovery code in the filed at the bottom. Click `Recover` button. Restart the printer when writing of the recovery code is completed.
