This is typically caused by an incorrect selection made during the LCD prompting after a cartridge is replaced or the hook did not snap securely over the ink cartridge when installing. Do the following to clear the message:

1. Open the ink cartridge cover. Pull the lock release lever and take out the ink cartridge for the colour shown on the LCD.

2. Reinstall the ink cartridge and lift each lock release lever and push it until it clicks, and then close the ink cartridge cover.

3. The LCD may then display:
   Did you change [colour name]?  Yes  No.
   The LCD may display this question for the colour that was replaced.
   BE SURE to select Yes using the up or down arrow key or Dial Pad. If  Yes is not selected for the replaced cartridges, INK EMPTY will appear again.
4. After all the correct selections are made, the machine will then go into the cleaning process. 

If the LCD displays "No Cartridge" there is a possibility that ink cartridges other than the ones you replaced are empty. Follow the steps below to check the ink volume. If there are other empty ink cartridges, please replace them.

1. Press Ink or Ink Management. *If your Brother machine does not have Ink or Ink Management key on the control panel,  please press Menu, then press the up or down arrow key to select Ink or Ink Management, and press OK.
2. Press the up or down arrow key to select Ink Volume and press OK.
3. The LCD shows the ink volume, press the up or down arrow key to select the colour you want to check.
4. Press Stop/Exit.

If the message "No Cartridge" does not disappear, unplug the machine from the AC power outlet and wait approximately 10 seconds, and then plug it back in. If the date and time appears on the display, the issue is resolved.
