Xerox WORKCENTRE 3210 Service Manual

2-24 WorkCentre 3210/3220 Multifunction Printer Service Manual
Theory of Operation
Developing Voltage (DEV)
The Developing Voltage is supplied to the Developer Roller to transfer to the
toner to the charge on the OPC Drum scanned by the laser beam while
printing the image. The engine controls whether the high voltage is supplied
and its quantity.
■ Input voltage: 24 VDC ± 15%
■ Output voltage: -200 V ~ 600 V DC ± 3%
■ Output voltage fluctuation method: PWM control
■ Line regulation: under ± 3% (fluctuation input 21.6 V~27.6 V)
■ Load regulation: under ± 3%
■ Output voltage rising time: 50 ms Max
■ Output voltage falling time: 50 ms Max
■ Output Control Signal (BIAS-PWM): The CPU output is HV output when
PWM is low.
