DEVELOPER BIAS
VOLTAGE CHECK
PURPOSE
The purpose of this check is to ensure that the
Developer Bias Voltage is within specifications.
Note: During normal operation the Developer
Bias voltage is determined by the Process
Control Setup. It will be between –450 and
-650 volts when the color is being developed.
1. Set up the multimeter to read 500 VDC.
2. Enter Normal Diagnostics (
Menu [3]

Enter [7]
, Power ON).
3. Use
