6.5.15. HIGH VOLTAGE VALUE CHECK POINT
Measurement Procedure
1. Open the TOP cover.
2. Remove the developing unit, if it is equipped.
3. Open the TOP cover, and turn ON the TOP cover SW.
(Push the TOP cover SW with a sharp-tipped insulator or insert folded paper, etc. to the slit.)
4. The unit enters the service mode when the TOP cover is open, then push *628.
(Don´t push the START button.)
5. Touch the output terminals under test with the high voltage probes.
6. Push the START button.
(This causes to output high voltage from each terminal, so be careful not to touch them. The sound “Pi Pi Pi” warns that the
high voltage is outputting.)
7. When the measurement is finished, push the STOP button.
(The high voltage output is stopped.)
8. Repeat the items No. 5~7 until the measurement is finished.
9. When the measurement is finished, turn OFF the TOP cover SW.
Output voltage of each terminal
No. BIAS Name Specified output voltage The range of specified output voltage
CHG (Charge) -1000V -1000V± 30V
DEV (Developing) -200V -200V± 15V
TRA (Transfer) -1000V -1000V± 100V
* As for the High Voltage test equipment, FLUKE 85 (MULTI METER)+ HIOKI (HV PROBE 9014) or the equivalent should be
used.
