Introduction
High Voltage Power Board (HVPS) has two kinds, a new type and an old (original) type. When replacing the HVPS or the parts on
the HVPS, first confirm if HVPS is a new type or an old type. A new type and an old type should be proceeded respectively with a
service according to each procedure.
If it is a new one, see the NEW TYPE VERSION (P.4). If it is an old one, see the service manual for KX-FL403UA (Order
No.KMF0606986CE).
The new type of HVPS and the old one have different parts respectively as shown above.
When ordering, make sure you order the correct parts.
For the new one, see the LOWER MAIN CABINET SECTION (2) (P.13).
For the old one, see the parts list of service manual for KX-FL403UA (Order No.KMF0606986CE)

HIGH VOLTAGE VALUE CHECK POINT
[Changed from original section “6.5.15. HIGH VOLTAGE VALUE CHECK POINT”]
6.5.15. HIGH VOLTAGE VALUE CHECK POINT
Measurement Procedure
1. Unplug the unit, and open the unit cover.
2. Remove the developing unit, if it is equipped.
3. Connect the wire to the terminal to be measured (Fig. 2). The wire should be put out of the unit not to interfere in other termi-
nals. See Fig 2 and 3 for fixing the wire to the terminal No.5.
4. Connect the wire fixed to the terminal to be measured and high voltage probe. Connect the earth of the high voltage probe to
the screw located under metal plate (Fig4, 5).
5. Reinstall the developing unit and close the unit cover.
6. Plug un the unit. It causes the unit to start the initial operation. Be careful, high voltage is output at that moment. (Avoid mea-
suring then.)
7. The unit enters the service mode. Then push *556_0. (Do not push the SET button.)
8. Push the SET button.
(High voltage will be added to the unit in the hereafter. Avoid touching the wire and the tip of high voltage probe where high
voltage is supplied.)
9. When the measurement is finished, push the STOP button.
(The high voltage output is stopped.)
10. Remove the wire fixed to the output terminal after measuring.
Each terminal’s output voltage
* FLUKE85 (MULTIMETER) + HIOKI (HV PROVE 9014) or the equivalent should be used as the high voltage measuring instru-
ment.
* As for measuring TRA, start measuring within 9 seconds after pressing the SET button. The output value will be changed in 9
seconds.
