KX-MC6020HX 6.17. HVU (High Voltage Power Supply Board) Section 6.17.1. High Voltage Circuit This board outputs 12 high voltages used for electronic photographic process. The 12 voltages consists of 2 charge ( VCH/YMC, VCH/K : -1001V ~ -1405V ) for color (YMC) OPC and black OPC, 4 development bias ( VB/Y, VB/M, VB/C, VB/K : DC -100V ~ - 300V + AC400V ) for each color, 4 supply bias ( VSR/Y, VSR/M, VSR/C, VSR/K : -200V ~ -400V), FTR bias ( FTR : 0V ~ 1800V ), STR bias ( STR : 0 ~ 5000V ).
Page 108 KX-MC6020HX 6.17.3. Development Bias Control Circuit This circuits of a DC-DC converter and a DC-AC converter. The DC-DC converter boosts +24V to approximately -100 ~ -300V for the development bias. The DC-AC converter adds the rectangular AC voltage to development bias. AC frequency value is approximately 800/1000 Hz that is determined by the external clock signal SCLKHV from IC300 (ASIC) on the main board.

Page 126: Print Process
KX-MC6020HX 6.20.4. Print Process This Laser Printer creates an image on paper using a technique called laser electrophotography. The printer uses the electro- graphic process known as Discharged Area Development, or “write black”. In this process, a digitally modulated laser scans later- ally across a rotating OPC (Organic Photo Conductive) drum that has been negatively charged.
Page 127: Laser Exposure
KX-MC6020HX Each block is explained in the following sections 1.Charging (See P.127) 5. Paper Pickup (See P.129) 2. Laser Exposure and Scanning (See P.127) 6. Toner Transfer to Paper (See P.130) 3. Developing (See P.128) 7. Fusing (See P.131) 4. Toner Transfer to the Accumulator Belt (See P.129) 8. Paper Exit and Paper Switchback (See P.132) 6.20.4.1.
Page 128 KX-MC6020HX 6.20.4.2.2. Laser Scanning A laser diode generates the laser beam, and lenses and mirror in the laser scanner direct the beam to the OPC drum. The beam is made parallel by the collimator lens and is directed at the rotating polygonal mirror, attached with the polygon motor. The polygon mirror rotates at a constant revolutions approximately 22,000 per minute.
Page 129: Paper Pickup
KX-MC6020HX 6.20.4.4. Toner Transfer to the Accumulator Belt As the OPC drum rotates, in contact with the accumulator belt, which is rotating at the same speed. Located under the accumulator belt at the contact point with the OPC drum, the first transfer roller carries a charge approximately +700 volts (FTR voltage). This strong potential attracts and holds the toner from the OPC drum to the accumulator belt.
Page 130 KX-MC6020HX printed on the paper. The registration sensor detects whether the sheet of paper arrived at the registration roller after being properly picked and traveling through the paper feed rollers in the optional lower Input tray. The paper feed unit has the standard paper cassette paper empty and registration sensors. The standard paper cassette has the MPT paper empty sensor for multi-purpose tray and the paper size detection levers.
Page 131 KX-MC6020HX 6.20.4.7. Fusing After toner image has been applied to the paper, it passes through the fuser. When the BK motor starts to rotate, the Halogen Lamp is turned on, heating the heat roller. As a result, the fuser belt, contacted with the heat roller surface, is heated by the heat roller. A heated fuser belt melts the toner and pressure drives it into the paper.
Page 132 KX-MC6020HX 6.20.4.8. Paper Exit and Paper Switchback 6.20.4.8.1. Normal Printing Mode (Not Duplex Printing Mode) After fusing, paper is fed to the output tray by the paper exit roller. Rotation from the BK motor is transmitted to the double teeth gear.
Page 133 KX-MC6020HX 6.20.4.8.2. Duplex Printing Mode (Paper Switchback) The switchback solenoid is turned off by the time the top edge of paper passes by the paper jam sensor on the fuser unit. The switching lever engages with the switching gear-A, and the rotation of rotation switching gear-A is locked. As a result, the rotation from the BK motor is transmitted to the paper exit roller in order of numbers (1 - 7) through the double teeth gear.
