After applying the current firmware update (CM27J9) to my WF4734 printer it has ceased to function, reporting "Cannot recognize ink cartridge Try installing again" For months prior I have used an aftermarket ink cartridge with no problems. Epson has apparently ignored Supreme Court decision 15-1189 (Impression Products v. Lexmark) of May 30, 2017 in making the decision to block usage of aftermarket ink cartridges. I am unable to locate the prior firmware version to download and reinstall (and of course will never do a firmware update or purchase an Epson product again). Short of attempting to instigate a class action lawsuit, what recourse do I have?
