CHAPTER 2 FUNCTIONS & OPERATION
2. Protection Function
The DC power supply PCB is a switching
regulator type.
If the load is shorted and there is an
over-current situation, the protection function is
activated and the output is stopped.
Once the output
automatically restored by turning the power
switch off, eliminating the cause of the short
circuit, discharging the capacitor (for about 10
minutes) and then turning on the power switch.
A fuse is used for protection on each PCB.
If an excessive current flows into the DC/DC
converter, the fuse blows and stops the power
supply to the PCB.
A fuse is also used for protection of the
main motor. If an excessive current flows in the
+ 24 VDC supplied to the main motor, the fuse
blows and stops the power supply to the main
motor.

3. Power Saving Mode

This machine will shift into the power saving
mode if no key or pick-up operation takes place
for 10 minutes or more, when the power is on. In
the power saving mode, power consumption is
minimized and the electrical circuits enter the
"sleep" state. The CPUs, however, do not shift
into power saving mode.
The machine shifts back to the standby
mode when any communication is carried out on
the computer side or when any key on the
operation panel is pressed.
Setting the power saving mode is carried out
in the user mode.
