If the machine’s sensor is not working, first open Settings and check whether “Auto-loading” is disabled. Enable it if necessary. Then try cutting any model and observe the roller. Normal roller rotation indicates that the sensor may be faulty and needs replacement. If the roller does not move, the symptom may instead indicate another issue, such as a motor or control problem.
What the Sensor Symptom May Mean
The sensor symptom has more than one documented troubleshooting path. The first condition to check is whether the Auto-loading option has been disabled in the machine’s settings. If the setting is enabled, roller movement can help distinguish a possible sensor fault from another type of machine issue.
A roller that rotates normally during a cutting attempt may indicate that the sensor itself is faulty. A roller that does not move may indicate a different problem, including a motor or control problem. Roller movement therefore provides the documented basis for deciding whether sensor replacement is the appropriate remedy.
Run the Supported Checks
Complete these checks in order so that the setting is verified before the roller test is interpreted:
- Check the Auto-loading setting. Open Settings and locate the “Auto-loading” option. If the option is disabled, enable it. Do not proceed on the assumption that the sensor is faulty until this setting has been checked.
- Observe the roller during a cutting attempt. Try cutting any model and watch whether the roller rotates. The result of this test determines which documented troubleshooting path applies.
Choose the Remedy Based on Roller Movement
If the roller rotates normally, the issue may be caused by a faulty sensor. In this situation, the documented remedy is to replace the sensor.
If the roller does not move, the available evidence does not identify the sensor as the confirmed cause. Instead, the lack of roller movement may indicate another issue, such as a motor or control problem. Sensor replacement is not documented as the remedy for this result.
Documented Expected Result
After completing the checks, Auto-loading should be enabled and the roller’s behavior should establish the applicable next action. Normal roller rotation supports replacing a possibly faulty sensor. No roller movement points away from a sensor-only diagnosis and toward another possible machine issue. No additional fixes or escalation steps are documented for the motor or control path.
