Without this chip, your printer will always indicate that the ink level in the cartridge is low even if the cartridge has been refilled. However, the printer will let you print anyways.

With this chip, the printer will accurately indicate the ink level.

This chip is calibrated to the number of pages of our refill kits. (3500 pages at 5% coverage)

This chip is designed for the following cartridges: X264A11G, X264A21G, X264H11G, X264H21G
