Please reset the drum counter only when you replace the drum unit. If you reset the drum counter during the life of the drum unit currently being used, the remaining drum life will not be displayed accurately.
Make sure that the machine is turned on.
Open the front cover.
Press Options on the control panel.
NOTE: The layout of a control panel differs depending on the model, but the Options button is located on the near side of the LCD screen as shown in illustration.
Do one of the following.
If your Brother machine has a numeric keypad:
Press 1 to reset the drum counter.
If your Brother machine doesn't have a numeric keypad:
Press the UP ARROW key to reset the drum counter.
When the LCD shows Accepted, close the front cover.
