Description:
When the system detects that the bottom cover is opened, it triggers the #903 error message indicating that the bottom cover is open. In typical scenarios, the system fails to detect the signal indicating the bottom cover is closed, resulting in the bottom cover icon on the panel not changing to the closed state. Another situation is when the bottom cover is securely closed; the error message randomly pops up during ongoing tasks.
Regardless of the symptoms your machine is exhibiting, please follow the steps below sequentially:
Step1 - Check the Icon on the touch panel
The icon located in the upper right corner of the touch panel can be used to determine whether the magnetic sensor detecting the bottom cover is recognized by the machine. Under normal circumstances, the bottom cover symbol should be in the closed state, indicating a normally closed condition.
b: Bottom Cover - Displays the machine's bottom cover status.
