  • Page 235 6.2.5 Picture Quality Control Circuit This circuit consists of a recording picture control standard cell IC140 (DZZAC000168 or “IPC”), an interpolation table ROM (IC141) and its peripheral circuitry. The recording picture control standard cell (IC140) inputs the serial data from the IC110 (DZZAC000167or “PEC”), conducts picture quality correction (smoothing), reduction, synchronization control, etc., then sends this data to the printer.
  • Page 236 6.2.6 Line Monitor Circuit The Line Monitor Circuit consists of an operational amplifier (IC100), analog master (IC91) and its peripheral circuits. Its function is to monitor the dial tone, DTMF tone, response signals, etc. over the speaker. It also sounds the output of the key touch tones, alarm tones, etc. from the panel CPU over the speaker.
  • Page 237 6.2.7 Transmit Motor Control Circuit The transmit motor is a stepper motor powered by +24 VDC and driven by a 1/2-phase excitation, greater step division is provided by controlling the phase circuit in steps. The stepping signal and chopping current control signals (pTINA, pTTDA, pTINB and pTTDB) are sent to the chopper drive circuit, comprised of IC190 and its peripheral circuitry, from the IC150 (S-CPU) output port.

  • Page 242 6.2.10 Control Panel The Control Panel consists of the Display PCB and Panel Unit, which display various status information. It is normally interfaced to the main CPU. Keyed input signals are received by the Panel CPU and the data is transferred to the main CPU on the FCB PC Board.
  • Page 243 6.2.11 Printer Motor Drive Circuit Motor Drive Circuit The Printer Motor is a Brushless DC Motor. When the nMMP2 signal level goes Low, the Printer Motor starts rotating. When the Printer Motor reaches a constant speed, the monitor feed back signal, nMMP3 goes Low and is fed back to the CPU which controls the printing process.The Printer Motor is powered by a +24 VDC supply.
  • Page 244 Fuser Lamp Drive Circuit The Fuser Lamp is powered by 115 VAC. It is driven by the LVPS and controlled the FCB PC Board. When the CN32, Pin 9 (nSSR) on the LVPS goes LOW, the Fuser Lamp turns ON. This lights up the PC301 LED and activates the CR301 photo-triac, and 115 VAC is sent to the Fuser Lamp.
  • Page 245 Fuser Temperature Control Circuit The Fuser temperature is controlled by IC51 on the LPC PC Board, which contains A/D (Analog/Digital) converters ANI0 and ANI7. The Fuser Temperature Control Circuit uses A/D converter, ANI1. When the PC301 drive current is transmitted from the LPC PC Board to the LVPS, the Fuser Lamp turns ON. IC55 is a converter with open output at pins 1 and 7 and is used as an abnormal temperature detection circuit.
  • Page 246 High Voltage Drive Circuit (Charging, Development and Transfer) High Voltage is provided through a DC to DC converter, which changes the +24 VDC supply voltage to - 650 VDC, and output approximately 0.72 KVAC (Steady current: 450 µA) for the Charging Block. The Developer Circuit converts the +24 VDC to between -500 VDC for the development bias, and outputs 1,700 VAC(p-p) at a frequency of 1.7 kHz to charge the toner.
  • Page 247 6.2.12 Interlock Safety Circuit This safety circuit turns OFF the +24 VDC supply voltages when the Printer Cover is opened. When the Printer Cover is opened, the microswitch(es) on the ILS PC Board are de-actuated, turning OFF +24 VDC to the Printer Drive Circuit, the HVPS, and the Paper Feed Solenoid Circuits, turning OFF the +5 VDC supply voltage for the Laser Driver Circuit on the Laser Unit.
