the original position temporarily.
(7) Do not use gloves that may cause static electricity easily when handling
IC and the circuit board such as microprocessor, ROM, and RAM.
(8) Do not put the PCB on the device and the floor directly.
(9) Do not work for a long time with the printer with the top cover open, and

There is a risk of electric shock during replacement of the low voltage power supply.
Use insulating gloves or avoid direct contact with any conducting part of the power
supply, and caution should be exercised during replacement.
The capacitor may take one minute to complete discharge after the AC cord is
