FAQs & Troubleshooting

The error message "Print Unable 72" appears on the LCD. What should I do?

The machine may not work properly because of the condensation inside of the machine caused by a temperature differential between the inside and the outside of the machine.

To clear the error message please follow the steps below:

  1. Keep the machine's power on and open the front cover.

  2. Leave the front cover open for 30 minutes.

  3. Close the front cover.

  4. Turn off the machine's power switch and turn it on again.

To avoid the condensation DO NOT place the machine in a location with severe temperature changes or a humid place (Ex. near a humidifier).
Use the machine only within the following ranges of temperature and humidity:

  • Ambient temperature: 20°C to 32.5°C (50°F to 90.5°F)
  • Ambient humidity: 20% to 80% (without condensation)


If the message "Print Unable72" continues to appear on the LCD the machine may have a mechanical problem. Please contact "Brother Customer Service".
