Hello everybody,\n\nI've fallen into the Epson trap ...\n\nFor 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.\n\nMy third-party ink is no longer recognized and I still have a whole box of it.\n\nAfter I calmed down, I'm looking for a solution ;-)\n\nI'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.\n\nDoes 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.\n\n\nThat would just be awesome! I will not buy any original ink from Epson because I just feel tricked.\n\nThanks and regards!!
