9. High-voltage transformer (HVT)
A circuit generates the output control voltage Vc of the main charger bias, main charger grid bias,
1st transfer roller bias, 2nd transfer roller bias, developer bias and cleaning blade bias.
10.Drum motor (M10)
This motor drives each drum and toner recovery auger. The drive of the motor is transmitted to each
drum by gears in the following 2 lines: Drum motor → K drum, drum motor → C drum → M drum → Y
drum
The gears and drum couplings are assembled with high precision in order to improve accuracy of
color overlay.
11. Drum switching motor (M11)
This motor switches ON/OFF the transmission of drive to the Y, M, C drums. When the motor rotates
normally or reversely, the gear of the motor moves the rack to shift the guides. And this movement of
the guides controls the transmission of the drive by engaging and disengaging gears which transmit
the drive to the Y, M, C drums. Additionally, the drum switching sensor detects the phase of the
guide to control the drum switching motor, and checks whether the drive is transmitted to the Y, M, C
drums or not.
12.Color drum phase sensor (S43), K drum phase sensor (S44)
This sensor matches the phase of Y, M, C drums and K drum. Matching the phase of each drum
improves the accuracy of color overlay. The actuator (disk) installed in the same shaft as the driving
gear of the K drum and C drum detects the position of their drums to match the phase.
