Service Manual
• Fuser Voltage
□ Input Voltage : 24 V DC ± 15%
□ Output Voltage : 0V ~ 1KV DC ± 3%
□ Output Voltage Rising Time : 50 ms Max
□ Output Voltage Falling Time : 50 ms Max
□ Output Loading range : 10 MΩ ~ 100 MΩ
□ Output Control Signal(Fuser PWM) : CPU is HV output when PWM is Low
2) SMPS (Switching Mode Power Supply)
It is the power source of entire system. It is assembled by an independent module, so it is possible to use for
common use. It is mounted at the bottom of the set.
It is consisted of the SMPS part, which supplies the DC power for driving the system, and the AC heater
control part, which supplies the power to fuser. SMPS has two output channels. Which are 5V and +24V.
• AC Input
