Downgrade of the firmware for Epson WF-3520 - looking for older firmware version

Sep 23, 2018
Hello everybody,

I've fallen into the Epson trap ...

For years I have used the Epson WF-3520 with third-party ink easily, now I have replaced my computer, reinstalled the printer while with the new firmware.

My third-party ink is no longer recognized and I still have a whole box of it.

After I calmed down, I'm looking for a solution ;-)

I've found instructions on how to downgrade the firmware via USB cable and keyboard shortcut on the device. The only problem: I can not find an older firmware version.

Does anyone happen to have a download link to an older firmware version for the Epson WF-3520? I found out that this is the firmware version CG29CA (29/10/2012), a google search did not produce any results.

That would just be awesome! I will not buy any original ink from Epson because I just feel tricked.

Thanks and regards!!
