Diagnose a Nonresponsive Sensor Using Auto-Loading and Roller Checks

If the machine sensor is not working, first check whether Auto-loading is disabled in Settings and enable it if necessary. Then try cutting any model while observing the roller. Normal roller rotation may indicate that the sensor is faulty and needs replacement. If the roller does not move, the problem may be elsewhere, such as with the motor or control system.

Documented Symptom and Possible Causes

A sensor that appears not to work does not automatically confirm a faulty sensor. The documented checks distinguish between an Auto-loading setting that is disabled, a possible sensor fault, and another machine issue. Roller movement during a cutting attempt is the key observation used to separate a possible sensor problem from a possible motor or control problem.

Check and Enable Auto-Loading

Start with the machine setting because Auto-loading may have been disabled. Complete this check before using roller movement to assess the fault.

1. Go to Settings.
2. Check whether the Auto-loading option is disabled.
3. If Auto-loading is disabled, enable it.

After this check, the documented expected result is that Auto-loading is enabled. If the sensor still does not work, continue with the roller movement test.

Test the Roller During Cutting

Try cutting any model and watch the roller during the attempt. The purpose of this test is to determine whether the roller operates normally when the machine is asked to cut.

• The roller rotates normally: The issue may be caused by a faulty sensor. In this case, the sensor needs to be replaced.
• The roller does not move: This may indicate another issue, such as a motor or control problem.

Use the roller’s actual movement, rather than the sensor symptom alone, to identify which documented outcome applies.

Expected Troubleshooting Result

These checks should establish whether the issue is associated with a disabled Auto-loading setting, a potentially faulty sensor, or another machine problem. Auto-loading should be enabled before evaluating the roller. If the roller rotates normally but the sensor remains unresponsive, sensor replacement is the documented remedy. If the roller does not move, the documented result points away from the sensor-only diagnosis and toward another possible motor or control issue.
