I put a new set of refillable carts with PiezoPRO in my new 3880 yesterday. All carts worked except position 8 (VLM) & 9 (Y). After multiple troubleshooting steps including putting a small soft shim under the OEM chip, then removing it, I finally got the printer to accept the IJM Yellow cart. But VLM is being very stubborn. In the meantime, LLK also became sporadic at being recognized. After 10-12 removals, adjusting the chip resetter, and re-inserting, I'm back to the only cart not working is VLM.
I made at least 20 adjustments with no success. I removed the OEM chip and placed it back on the empty Epson VLM cart, and carefully inserted it in the printer. The printer screen displayed non-Epson ink is inserted and gave a warning on printer functionality with non-OEM ink. I had to select "AcCCEPT" in order to continue. The printer immediately did a 100% ink charge before allowing me to open the ink cover and replace the empty VLM Cartridge with the IJM cartridge. However, I again got the error "Please Install the Correct Cartridge"
It appears there is an issue with the IJM VLM cartridge that I received. Is there any possibility of replacing it this week?
