I had one of the latest firmware uploaded to the epson website. He was up to date. I just installed a CISS. The printer indicates error message :ess4.jpg.119116ddeaacbddda918ccdb3a555339.jpg

I proceed then as indicated in your tutorial to downgrade :

Printer in firmware update mode :

Launch EPFWUPD.exe ( http://chiplesssolutions.com/download/WF7710_FWG535TL_FA24I5.zip)

Download and extract this Firmware Version - FA99Z9 - http://chiplesssolutions.com/download/WF7710_FWG535TL_FA99Z9.zip
Upload firmware to  printer in normal mode  - dont put printer in Program Update mode -  the printer will restart , but the firmware won't get 100% - about  80%  -  just close it in task manager

After you get error message -  firmware wasn't installed properly - just use License.exe utility

Please reply about results.

The printer now works with the ciss thanks to your latest solution.

It was also necessary to do a manual cleaning of the nozzles.

Thank you for your promptness.
