I installed the recently ordered refillable cartridges and the blue gets "cannot recognize" error message.  Reinstalling the cartridge sometimes helps for a couple of minutes, and sometimes not.  Problem seems to be getting worse.  I've cleaned contacts with alcohol, no change to symptoms.

Same issue for me with Magenta on my Workforce 323.  They sent me new chips to install myself instead of a new M cartridge.  No clue how to install the new chips.  Searching for that now, I may call them back.

UPDATE: Chips are easy to change out.  Found it on an old thread.  Just slide to the left. Replaced chip.  Now my printer doesn't recognize MAGENTA or BLACK.

UPDATE #2:
Epson cartridge was the solution last time. 

Epson sent me a new magenta chip AND a whole set of chips.  Replaced magenta chip; not recognized.

Unplugged unit. Restarted.  BLK cartridge now not recognized.  Replaced with new chip (assumed 125R4 would be the correct one). BLK and Y not recognized. 

Replaced old chip on BLK cartridge.  Unplugged. Restarted.  Epson seems happy.  For now. 

Still, it feels like I'm chasing a moving target.  Put this QUESTION to Epson.  I'll update when I get an answer: Do the cartridges have corresponding chip numbers?  You sent a set: 125R1-4. If/when I replace the set, which chip goes in which cartridge?

Did you already check the small battery behind each chip?? If you were to pry the chip out of the cartridge then you should see a slot for a small watch battery.

If you replace that tiny battery, then you should be able get the cartridges to work for you once more.

I'm now having the same problem with the magenta, replacing the chip on the blue corrected the problem the first time, do I need a new chip for this cartridge also?

hey docwatson99.

That could be the case for you. But before you go into a new chip, copy and paste the link below. You will need a screw driver, what you will do here is manually jump the chip which will force it to reset itself.

Hold the screwdriver down on the contacts for 5 seconds and then re-install the cartridges.

I tried the reset procedure and the magenta cartridge is working again.

I now have the same problem with both the blue and the black cartridge.  The previous "reset" proc doesn't seem to change the problem at all.  Any other solutions?

Hello,

On the back of the 3520 chip which you have. If you slide it to the left from the carriage you would be able to remove the chip from the cartridge. Once you remove the chip if you look on the back side of it you will notice that there is a small silver harness which holds a battery inside of there. If you are unable to do the old reset trick, that would mean that the battery on the back of the chip has to be replaced. You would be able to purchase a replacement battery from your local market/store.
