What safety precautions should be followed before servicing or disassembling the printer?

Before servicing, always turn OFF the power source according to the specified steps and disconnect the power plug. Never disassemble the machine while the power supply cord is connected to the inlet, as power is supplied to the AC line even when the power switch is turned OFF due to the remote switch control circuit. Additionally, be careful of sharp corners, edges, springs, and protrusions that may cause injury. (Page 3)
