The Chip Resetter is equipped with 3 pins and the chip on the Brother cartridge has 3 matching contact areas. When you press the 3 pins to the 3 contact areas the LED on the Chip Resetter lights up red. After about 1 second it turns to green. That is when the Chip Resetter has reprogrammed the Chip on the cartridge. When you have refilled the cartridge you can insert it back into your printer and continue printing.

The Brother LC-223, LC-225, LC-227, LC-229 cartridges are equipped with a chip. This chip measures the ink filling level and thus prevents you from dry printing with an empty cartridge.

But what happens if you refill the cartridge. The printer still gets from the chip the information that the cartridge is empty (see the pictures). You have 2 options to handle this situation: You can ignore the message from your printer or reset the chip with the suitable Chip Resetter.

Option 1: Ignoring the filling level indicator.

The printer informs you that one of the cartridges is empty. He wants you to exchange the cartridge with a new original cartridge from Brother. You can ignore this message by pressing the red X-button. When you start a new printing job a new message may occur: “Ink filling level can not be detected”. Simply press the red X-button and the printer starts printing.

The disadvantage of this method is the constant appearing of warning messages. They sometimes appear before every print job. Another problem could be that you forget to refill the cartridge and print with an empty one. In this case there may air bubbles get into the tubes that connect the LC-223, LC-225, LC-227, LC-229 cartridges to the print head. It takes quite some time to get this air out again.
