2-14 Phaser 3140/3155/3160 Printer Service Manual
Theory of Operation
Supply
• Output voltage: -400 V ~ -800 VDC ± 50 V (ZENER using, DEV)
• Input contrast of the output stability degree: under ± 5%
Loading contrast: ± 5% or less
• Output voltage rising time: 50 ms Max
• Output voltage falling time: 50 ms Max
• Output Loading range: 10 M Ohm ~ 1000 M Ohm
• Output control signal (BIAS-PWM): The CPU is HV output when PWM is Low.
Power Supply
The Power Supply (switch-mode power supply, SMPS) supplies DC power for driving
the printer, and the AC heater control, which supplies power to the Fuser.
The Power Supply has two output channels: +5.0 V and +24 V.
AC Input
• Input rated voltage:
• AC 110 V~127 V
• AC 220 V~240 V
• Input voltage fluctuation range:
• AC 99 V~140 V
• AC 198 V~265 V
• Rated frequency: 50/60 Hz
• Rated frequency fluctuating range: 47~63 Hz
• Input current: under 4.0 A/2.0 A (when the lamp is Off or rated voltage is
inputted/outputted)
