11.2.16. HIGH VOLTAGE VALUE CHECK POINT
Measurement Procedure
1. Turn Off 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 (Fig. 3). See Fig 4 and 5 for fixing the wire to the terminal No.4.
4. Reinstall the developing unit and close the unit cover.
5. 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 the bottom plate of the unit without the paper cassette. (Fig.1)
6. Turn On 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 *628_0.
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. (Fig.6)
* As for measuring TRA, start measuring within 9 seconds after pressing the SET button. The output value will be changed in 9
seconds.
