Only suitable for use on original cartridges. Do not use on 123ink chipped cartridges. Click here for full instructions.
When your printer reads the ink levels in your cartridges it does so via a chip in the cartridge itself.
Unfortunately the ink levels reported to you by your printer are only estimates and often a cartridge will be reported as empty when there's still usable ink left in it. If you've never used a chip-resetter before then you've probably thrown out perfectly good ink!
Using a chip-resetter will "reset" the chip and allow you to use any leftover ink in the supposedly empty cartridge.
Save money and the environment by making cartridges last longer before you throw them out.
