  • Page 66 Circuit Description 4-4-2-8. MHV (Electrification Output Enable) Electrification Output Enable is the electrification output control signal 'PWM-LOW ACTIVE'. When MHV-PWM LOW signal is received, Q401 turns on and the steady voltage will be accepted to the non-inverting termi- nal of OP-AMP 324. As the voltage higher than the inverting reference voltage of OP-AMP, which is set to R405 and R406, OP-AMP output turns high.
  • Page 67 Circuit Description 4-4-2-9. BIAS (supply/dev output unit) BIAS voltage output is generated only when electrification voltage is set to output. In the circuit presented above, it organizes enough zener-diodes required to output dev/supply voltage from electrification output. Supply voltage is output when the supply-ea signal is 'L'. When supply-ea is 'L', Q104 turns off and as Q105 does not turn on, the electric potential of the output unit retains the electric potential of zener and thus -500V is output as the supply voltage.
  • Page 68 Circuit Description 4-4-2-10. THV(THV(+)/THV(-) Output Unit) Transfer(+) output unit is the transfer output control signal 'PWM-LOW ACTIVE'. When THV-PWM LOW signal is received, Q203 turns on and the steady voltage will be accepted to the non-inverting terminal of OP-AMP 324. As the voltage is higher than the inverting reference voltage of OP-AMP, OP-AMP output turns high. The 24V power adjusts the electric potential to ZD201 and ZD202, sends IB to TRANS auxiliary wire through current-restrict- ing resistance R215 via R212 and C204, and eventually Q204 will turn on.
  • Page 69 Circuit Description 4-4-2-11. Environment Recognition THV voltage recognizes changes in transfer roller environment and allows the voltage suitable for the environment in order to realize optimum image output. The analog input is converted to digital output by the comparator that recognizes the environ- mental changes of the transfer roller.
