Epson Printer Not Recognizing Ink

my Epson printer rejecting OEM print cartridges immediately after updating the software to my computer. I have powered the printer off and unplugged it for three days (waiting on replacement ink) when new ink arrived (yellow) and I installed it (other inks were showing 1/2 full on computer before I ordered the yellow only) When I inserted the new Yellow cartridge the blue one immediately reported as not recognized. I have MULTIPLE ink cartridges from these last two complete set purchases that either report as empty when they are not, or as not recognized. ALL ARE OEM. If this is not corrected, this will be my last EPSON purchase.

Using a ink cartridge chip resetter usually helps. They can be purchased online.

Been there, tried that, didn't work.

Le même problème avec ma cartouche rouge OEM 26XL ref T02633

What was the solution?

[@tiredofliars]

There has been none, it has been over a year, and I rarely use the printer, but it is time to change three of the inks, so, I will change all of them at once and do a new video showing how crooked Epson has become.

@@tiredofliars The issue is caused by firmware. In older firmware versions the problem would appear after running an update. In more recent firmware versions the problem appears to occur after uninstalling/reinstalling the cartridge. The printer memorizes each cartridge and estimates ink levels to prevent use of third party cartridges. The easiest solution is to flash the firmware back to the previous recommended version. This will require the provided printer cable and the model number. The previous firmware is provided on Epsons website.
