Issue description

When using your xTool OS1 Automatic Shaker Oven Machine, you receive an "Exhaust fan exceptions (Error code: X)" error message displayed on either the xTool Creative Space (XCS) software or the oven's touchscreen control panel.

Potential causes

• Poor exhaust fan cable connection: Loose or disconnected wiring between the exhaust fan and the main control board;
• Exhaust fan failure: Hardware malfunction of the exhaust fan motor or components;
• Main control board issue: Abnormal voltage output from the oven's main control board;

Troubleshooting

Step 1: Reconnect the exhaust fan cable

Tools Required:

• M2.5mm Hex screwdriver (included with your xTool package)

⚠️ Important Safety & Preparation Notes:

• Printer Removal: Before starting the inspection, remove your xTool Apparel Printer from the top of the OS1 oven by unscrewing the two installation screws.
• Power Safety: TURN OFF the oven's main power switch and UNPLUG the power cord from the wall outlet.
• Printer Power: Once the printer is uninstalled, reconnect its power supply to ensure it remains powered on for its auto-maintenance function.

Procedure:

1. Use an M2.5mm Hex screwdriver to remove the screws securing the left-side panel of the oven. Carefully set the panel aside.

2. Locate the main control board inside the oven.
3. Unplug and then firmly re-plug the connector for the exhaust fan on the main control board. Refer to the image below for the connection point.

4. Plug the power cord back in and turn on the oven's power switch to test the oven.

If the issue persists, proceed to Step 2.
