After reviewing your order history, I see you purchased the R3000 refillable carts and ConeColor ink in March, then just bought a set of replacement chips a few days ago.
R3000 chips are color position specific, so installing carts in the wrong positions, or switching chips on carts will not work (as you discovered).
Due to the age of the carts, you may be dealing with old/dead batteries, which will cause chip/cartridge recognition issues you’re experiencing- in this case new chips with fresh batteries will resolve the errors.
If the chips were not fully attached to the carts, then you could have damaged the thin wires of the chip sensors, which would cause a cartridge error. With cartridges removed, please examine the chip sensors in the printer and compare a good working one to the LK, MK and PK positions that are giving you an error.
Please keep me posted after you have tried the new chips, and let me know if you have further questions or there’s anything else I can help you with.
Best regards~ Dana
