CHANGES TO IMPROVE TORQUE TRANSMISSION EFFICIENCY

The size of color registration errors has been reduced with changes in the design of the
drum motor.

Drum Motor Shaft

B132/B200
In the B132/B200, the drum motor shaft and drum motor are separate components. In the
new D014/D015 drum motor, however, the shaft and motor are permanently connected. This
direct-drive arrangement improves the performance of the drum motor and shaft. Also, for
the D014/D015 drum motor, the rotation wave fluctuation of has been reduced by 30%.
In addition to this change in drum motor design, the FB (Feedback) control system has been
improved to reduce color registration errors.
