No chip need to replace chip. (CLI 8 or CLI221)
can you help?
The chip is a sensor that helps the printer to recognize the cartridge and the ink level.
For NO-CHIP ink cartridges, you will have to replace the chips from the OEM original ink cartridges (genuine) ink cartridges to our new replacement ink cartridges, and we have instruction inside of the box, you can follow the instruction to replace the chip.
Or you can follow the instruction here to replace the chip.
Personally, we would recommend you purchasing those ink cartridges with chips, since they will save you from unnecessary efforts and potential trouble.
Feel free to contact us if you have more questions.
