Hello @John_Admin and @wic.support: I have a Epson XP-15000 that I (stupidly) updated and there is conflicting information if a firmware activation key is available for this model... Within the WIC Reset Utility (v5.59), it looks like the answer is no, but on 2Manuals.com, it clearly states that this machine can indeed go chipless. Any chance you could give me a clear answer and direction on this? I just want to be able to print with the numerous non-OEM cartridges I've invested in. Thank you.
