2.1.2.6 Bias Voltages and Laser Drive Timing
Figure 2-27 is a diagram of the drum charge bias voltage, image transfer bias voltage, doctor blade
bias voltage, and the developing bias voltage control circuit. These bias voltages are generated
from the +24
from the high voltage supply board
If the printer detects a case open
condition, the interlock switch is set to OFF, which cuts the +24
which, in turn, cuts the bias
voltages.
These bias voltages are controlled by the engine controller board
The

signal is the image transfer (roller) bias voltage control. While this signal is LOW, the image
transfer roller is charged to
