3.3.15 High Voltage Power Supply
[Function]
- Deflection voltage output : DC 5.7kV Max.
Charge signal source voltage output : DC500V
[Note at the replacement]
- When replacing the high voltage power supply, be sure to turn off the power.
- If the high voltage line is dusty, a fault may occur due to a leakage of high voltage.
Wipe the dust off the line in the case where it is dusty.
- When connecting the deflection voltage output connector, be sure to joint the connector
to right position.
[Replacement procedure of high voltage power supply]
(1) Turn off the main power and open the maintenance door.
(2) Remove the wire harness from the wire clamp put on the high voltage power supply
protective cover.

(4) Remove the high voltage power supply.
Remove the two fixing screws and two fixing spacers.
(5) Install a new high voltage power supply by reversing the above procedure.
Check the clamping position of wire harness.
Caution against an electric shock
The high voltage power supply has a portion where high voltage is applied. In order to
avoid an electric shock, be sure to turn off the power before access the high voltage power
supply.
