Assembling Note:
- As the DCLN coil spring and CHG 1 coil spring tend to come out of the Side frame R, be
careful not to lose them.
-
When assembling the High-voltage power supply PCB ASSY, make sure that the CHG 1 coil
spring and CHG 2 coil spring properly come into contact with the electrodes. If not, Drum
Error will occur
