III. POWER SUPPLIES

A. Outline

The power supply unit uses a remote switch.

When the printer power switch is turned ON, the printer outputs a command to the option

controller through the video controller. The option controller outputs a POWER ON signal
(PWRON-IN) to the power supply unit through the paper deck driver according to the
command. When the PWRON-IN signal is “H”, the power supply unit pr24 V and +5 V
to the paper deck driver.

+24 V is used to drive the lifter motor, feed motor, pick-up motor, clutches and solenoids,

and +5 V is used for sensors and ICs on the paper deck driver PCB.

The power supply unit uses the stand alone mode switch (SW1). This allows the paper deck

to be ON while the printer is OFF.

A block diagram of the power supply unit is shown below.

Figure 2-3-1

B. Protective Function

The +24V and +5V power supply circuits have the overcurrent protection function and the
overvoltage protection function that interrupt the output voltage automatically to prevent
failure of the power supply circuits if a trouble, such as a short, occurs in the load and results
in overcurrent flow or occurance of abnormal voltage.

Therefore, if the overcurrent or overvoltage protection function is activated and the DC

voltage is not output from the power supply circuit, turn the printer OFF, correct the trouble in
the load, and turn the printer ON again.
