  • Page 34 Summary of Product 4.4 SMPS & HVPS The SMPS and HVPS are on one integrated board. The SMPS supplies the DC power to the system. It takes either 110V or 220V and outputs the +5V and 24V supplies to the main and other PBAs. The HVPS creates the high voltage of THV/MHV/Supply/Dev and supplies it to the toner cartridge.
  • Page 35 Summary of product 4.4.1 HVPS(High Voltage Power Supply) 1) Transfer High Voltage (THV+) - Function : It is this voltage that transfers toner from the OPC Drum to the paper. - Output voltage : Maximum +5000V ±5% (no load, variable duty cycle) - Error : IF THV (+) is not present, low density printing occurs due to toner on the OPC Drum not being transferred to the paper.
  • Page 36 Summary of Product 4.4.2 SMPS (Switching Mode Power Supply) This is the power source for the whole system. It is an independent module so that it is possible to use it for common use. It is mounted at the bottom of the set. It consists of the SMPS section, which supplies the DC power to drive the system, and the AC heater control part, which supplies the power to the fuser.

(at 1500Vzc, 10mA) - Leakage voltage : under 3.5mA - Running voltage : under 40A peak (at 25°c, Cold start) Under 60A peak (in other conditions) - Rise Time : Within 2Sec - Fall Time : Over 20ms - Surge : Ring Wave 6KV-500A (Normal, Common)
  • Page 38 Summary of Product 4.5 Engine F/W 4.5.1 Feeding If feeding from the cassette the drive of the pickup roller is controlled by controlling the pick-up solenoid. The on/off of the solenoid is controlled by controlling the general output port or the external output port. If feeding from the manual feeder the set decides to feed the paper according to the operation of the manual sensor, and by driving the main motor, insert the paper in front of the feed sensor.
  • Page 39 Summary of product 4.5.4 Fusing The temperature of the heat roller's surface is detected according to the resistance value of the thermistor. The thermistor resistance is measured using the A/D converter and thus the CPU can determine the temperature of the heat roller.
