These are replacement chips for our refillable ink cartridges. These chips are usually found on the side or top of our refillable ink cartridges. They contain information that the printer needs to run. Occasionally these chips can fail. If they won’t reset with your chip resetter you may need to replace the chip. The printer will cease to print if the chip becomes corrupted. These chips are color slot and printer model specific and sold as a complete set for your particular printer model. We highly recommend keeping at least one back up set available at all times.
