There are a various reasons to maybe why the chip is not recognizing inside the printer .
First, here are the easiest solutions to the most common issues/fixes.
It's possible that the chip may need to be re-aligned, so removing them and re-installing them back onto the cartridges will re-align the position of the chips. I would then take some rubbing alcohol and clean the contacts on the print head, just to remove any residue that may be on the chip, blocking the transmission to the print head.
Here is a video on how to remove and re-install the chips. https://www.youtube.com/watch?v=BTSrd9I3ZBM
If this does not solve the issue, then you may need to perform a Hard Reset, which WILL REQUIRE the Original Epson Cartridges.
Hard Reset :
Take out cartridges,
Then Unplug the printer,
wait 15-30 seconds,
Then plug into the printer,
Plug OEM's back inside,
Let them recognize, then plug our CISS cartridges back in.
Lastly, if this does not work, I would recommend contacting us to get your chips replaced.
It's very likely that the firmware is blocking the chips from reading into the printer, but these are the most common fixes that we have to get the systems working.
