WF 3640 new firmware update

[Ink stained Fingers]

a firmware change may be possible with some maintenance software/utility but that gets charged as well.

the 3620/3640 printers can actually detect if you are using non epson carts but will let you continue anyway. they warn about all sorts of dire consequences but don't stop the cartridges from working. still a good idea not to run firmware upgrades because if it aint broke dont fix it. We have a 3640 and 2 7610s (the wide carriage version) going on several years now and all are working with compatible cartridges from Edit: by Moderator

@techsavvy, What association do you have with the ink supplier you keep mentioning in this and your 2 previous posts. !

Yep, I get the messages all the time and just keep pushing forth.

I called Epson customer service directly about the new Firmware Update and the Error I received on my WF-3640. It displayed on the printer an error code of 0x9A. First I just updated it because I was out of the country for two years and the printer was working fine for the last 2 months I have been back in the US before I decided to do the update.

Epson Customer Service is sending me a Refurbished WF-3640 by Fedex at no cost. They did take down my CC for 119.00 if I don't return the old one back to them. They did check and mine is out of warranty but they want to see what was causing this error.

DO NOT TRUST Third Party repair or let Third party get access to your computer (Remote In) EVER to fix your computer issues. They are SCAMing you for money.

Like with WiFi routers, the only reasons to update firmware of your printer is if it will fix something that is malfunctioning or to add functionality you must have. If the printer ain't broke then don't fix it.
Fortunately you were spared buying a new printer because of Epson's curiosity.

Thanks for telling your story. It is a warning to others that are thinking of doing the same.
