The RJ Utility is a computer program that allows you to change the printer's default settings. This utility can be used to adjust settings that are more advanced than the printer driver’s settings.

Before Using the RJ Utility:

• Connect the printer to an AC or DC power outlet, or make sure that the battery is fully-charged.
• Make sure that the printer driver has been installed and is functional.
• Connect the printer to a computer via USB or Bluetooth^® (RJ-4030/4030Ai).

Starting the RJ Utility:

1. Connect the printer to be configured to the computer.

2. Start the Printer Setting Tool.
   For Windows 11 / Windows 10
   Click [Start] - ([All apps] - [Brother] -) [Printer Setting Tool].

   For Windows 8/8.1
   Click the [Printer Setting Tool] icon on the [Apps] screen.
   For Windows 7 / Windows Vista
   From the Start menu, click [All Programs] - [Brother] - [Label & Mobile Printer] - [Printer Setting Tool].
3. Select the printer connected in step 1.
4. Click the [Device settings] button. The main window is displayed.

How to Use the RJ Utility:

1. In the main window of the RJ Utility, check the parameters with settings that can be changed.
2. Select the desired settings from the pull-down menus or enter the desired values.
3. Click [Apply] to save the settings in the printer.

   The settings are saved when you quit the RJ Utility, and the settings are applied the next time the RJ Utility is started.
   If the printer is already connected when the RJ Utility is started, the printer's settings are applied.
