This article aims to explain the process of the ceramic resistor test and is compatible with the following models:
✅ Maker Series
✅ Pronto Series
✅ Pro Series
The process typically takes approximately 10 minutes.
The ceramic resistor test is NOT required upon first receiving the machine. Perform this test only when the machine is malfunctioning, and the root cause is unknown. The test helps determine whether the fault originates from the laser power supply.
The ceramic resistor (as shown below) is usually included in the machine’s accessory bag.

You can watch this video or follow the step-by-step instructions to perform the test.
While performing the test, we recommend following these safety instructions:
