Given I have *no* idea how to fix your printers, I do have a method to keep this
*&^%*&^%
from happening to you,
or others, in the future. These printers obviously use WiFi,
the WiFi signals all come from/through your router, and the printer's ID (MAC address?)
has long ago been sent to OEM. OEM can thus communicate -
individually- with your printer.
Most routers have a built-in Firewall, which can block various "websites", including those
OEM uses to communicate with your personal printers (and presumably, shut them down).
Here's the generalized method to activate router firewalls, and use them, to block printer's
communication with OEM:
LINK TO Lifewire Page. NOTE: Router firewall is
different from
the firewall you have using Windows' OS, or Apple's OS.
What sites need to be blocked is way beyond my knowledge, but I suspect someone
here has a friend who works in IT.
.Good Luck !
EDIT: I wonder if blocking the OEM sites on the internet will allow the printers to recognize
new
non-OEM+ (??) cartridges and/or aftermarket cartridges?? Might be worth a try.
.
BTW... Blocking Epson via firewall should not interfere with
you controlling your printer.
