4. REPLACEMENT AND ADJUSTMENT
4.1 GENERAL CAUTIONS
4.1.1 NOTES ON THE MAIN POWER SWITCH
The main power button of this machine has been changed to a push-button switch (push button)
from the conventional rocker switch. The push switch has characteristics and specifications
different from the rocker switch. Care must be taken when replacing and adjusting parts.
Characteristics of the Push Switch (DC Switch)
Power is supplied to the machine even when the main power switch is turned OFF.
The push switch in this machine uses DC (direct current). Therefore, if the AC power cord is
connected to an electrical outlet, power is supplied to the controller board, the operation unit
and other modules even when the main power is turned OFF. When replacing the controller
board and the operation unit in this state, not only these boards, it will damage other electrical
components.
So, when performing maintenance work such as replacing parts, in addition to turning off the
main power with the push switch, always unplug the AC power cord.
When you disconnect the power cord from the AC wall outlet, inside the machine there is
still residual charge.
When you disconnect the power cord from the AC wall outlet, inside the machine for a while
there is still residual charge. Therefore, if you remove boards in this state, it can cause a
blown fuse or memory failure.
--How to remove the residual charge inside the machine--
After you unplug the power cord from the AC wall outlet, in order to remove the residual
charge from inside the machine, be sure to press the main power switch. Thus, the charge
remaining in the machine is released, and it is possible to remove boards.
When you reconnect the AC power cord into an AC wall outlet, the machine will start
automatically.
In order to remove the residual charge, push the main power switch while you disconnect the
AC power cord. At that time, the power ON flag inside the machine is set. Therefore, after you
finish work on the machine and reconnect the power cord to the AC, even if you do not press
the main power switch, the machine will start automatically and the moving parts will begin to
move. When working on moving parts, be careful that fingers or clothes do not get caught.
