even when the switch is OFF unless the power cord is
unplugged from the wall power outlet. Unless otherwise stated

code from the wall outlet before disassembling or assembling
the printer to prevent electric shock and damage to the circuit.

circuit) for memory backup. Be sure to observe the following
