WARNING
Before disassembling, assembling, or adjusting the printer, disconnect the power supply cable from the AC power socket. Failure to do so can cause physical injury.
The power switch is wired in the secondary circuitry of the power supply board. Therefore, the power supply’s primary circuitry remains
Tlive even after the printer is turned off.
Never touch primary parts of the power supply unit (including the heat sink) while the printer is plugged in.
