II. PRIMARY CHARGING ROLLER BIAS CONTROL

A.

Outline

The primary charging roller bias is controlled by the DC controller PCB’s CPU

(IC301). AC bias as well as DC bias is applied to the primary charging roller in order to
stabilize the charging.

• DC bias fixed voltage control
• AC bias fixed current control
• Bias switching control

B.

Control operation

The outputs of the DC bias and AC bias, which are applied to the primary charging

roller, are controlled by the DC (DCPWM) control signal and AC (PRACON) control sig-
nal respectively, which are output from the CPU (IC301). The DC bias, which is output
from the DC drive unit, is detected by the DC voltage sensor circuit, and is fed back to
the DC drive circuit via the comparison circuit. In this way, the CPU controls the primary
high-voltage DC component (constant voltage control).The AC bias output is detected
by the AC current control circuit, is fed back to the AC drive circuit via the comparison
circuit, and controlled by the CPU (constant current control).

Furthermore, the bias output to the primary charging roller of this unit changes

depending on the print resolution (1200dpi equivalent or 600dpi equivalent).

The bias output switches between the DC and AC drive circuits, in response to the

bias switching signal (1200dpi equivalent) from the CPU.
