¶ Issue Description
On the inner side of the printer's right front column, there are two Hall sensors positioned at the top and bottom respectively, which detect whether the front door is properly closed. When the Hall sensor wiring becomes loose, the system fails to recognize the front door status, triggering an alarm.
The possible causes of this fault include:
- Loose connection between the Hall sensor wire and the Hall board;
- Loose connection between the Hall sensor wire and the MC board;
- Broken wire connection.
¶ Troubleshooting
¶ Tools, Equipment, and Materials
- H1.5 hex wrench
¶ Solustions
Users may adjust the order of these solutions as needed.
- Check whether the connector on the Hall board is securely installed, and try reseating it if necessary.
- If reseating the connector does not resolve the issue, the wiring may be broken or the connection to the MC board may be loose. Please contact customer support for further troubleshooting assistance.
