Motor Driving
The main motor driving circuits is on the BLDC Motor Assembly Unit. Main Controller has
the interfacing circuits. There is motor driver IC on the motor control board of Motor
Assembly Unit.
The exit motor driving circuits is formed when the driver IC is selected. The AN44060A
Motor Driver IC is used in this case. The resistance Rs value for sensing and voltage
value for the V reference can be changed by motor driving voltage value. The motor driv-
ing voltage is calculated with the following formula.
The motor driving circuit is formed when the Driver IC is selected. The A3977 Motor Driver
IC is used in this case. The resistance Rs value for sensing and voltage value for the V
reference can be changed by motor driving voltage value. The motor driving voltage is cal-
culated with the following formula.
I = Vref / Rs, wherein Vref is (R1 x 5V) / (R1+R2)
SMPS & HVPS board
The SMPS supplies DC Power to the System.It takes 110V/220V and outputs the +5V, +24V to
supply the power to the main board. The HVPS board creates the high voltage of THV/MHV/Sup-
ply/Dev and supplies it to the developer part for making best condition to display the image. The
HVPS part takes the 24V and outputs the high voltage for THV/MHV/BIAS. The high voltage out-
put is supplied to the toner, OPC cartridge, and transfer roller.
HVPS (High Voltage Power Supply)

Transfer High Voltage (THV+)
-Input Voltage: 24 V DC 15%
-Output Voltage: MAX +5.0KV 5%,(Duty Variable, no loading)
->1.2KV 15% (when cleaning,200)
-Output Voltage Trigger: 6.5
-Input contrast of the Voltage stability degree: under 5% (fluctuating input 21.6V ~ 26.4V)
Loading contrast: 5% or less
-Output Voltage Rising Time: 100 ms Max
-Output Voltage Falling Time: 100 ms Max
-Fluctuating transfer voltage with environmental various: +650 V(Duty 10%) ~ 5 KV (Duty
90%)
-Environment Recognition Control Method: The THV-PWM ACTIVE is transfer active signal. It
detects the resistance by recognizing the voltage value, F/B, while permits the environmental
recognition voltage.
