Page 194 6.2.6. PNL PC Board The PNL PC Board Assembly consists of the Panel CPU, LCD Module with BackLight, LED, A-Point Sensor, B4-Width Sensor (Specified Destinations only) and Key Switches. The Panel CPU is interfaced to the main CPU on the SC PC Board. The CPU controls LCD and LED by the command signals from the main CPU, which also detects the signals of Key Switches and Sensors.

Page 196 6.2.7 Laser Printer Drive Circuit 1.Motor Drive Circuit The Scanner/Printer Motor is a 4-phase uni-polar PM-type step motor. The step signals (A to nB) are transmitted to IC26 (the Chopper Drive Circuit) by SHINE(IC3). The chopper current is determined by the voltage at IC26, Pin3 and Pin13.
Page 197 2. Fuser Lamp Drive Circuit The Fuser Lamp is powered by 115 VAC. It is driven by the LVPS and controlled by the nSSR signal from the SC PC Board. When the CN103, Pin11 (nSSR) on the LVPS goes LOW, the Fuser Lamp turns ON. This lights up the PC001 LED and activates the CR001 photo-triac, and 115 VAC is sent to the Fuser Lamp.
Page 198 3. Fuser Temperature Control Circuit The fuser temperature is controlled by IC1 on the SC PC Board, which contains A/D (Analog/Digital) converters ANI0 to ANI7. The Fuser Temperature Control Circuit uses A/D converter, ANI1. When the PC001 drive current is transmitted from the SC PC Board to the LVPS(PSU), the Fuser Lamp turns ON. IC23 is a comparator with open output at pins 1 and 7 and is used as an abnormal temperature detection circuit.
Page 199: Interlock Safety Circuit
6.2.8 Interlock Safety Circuit This safety circuit turns OFF the +24 VDC supply voltages when the Cover is opened. When the Cover is opened, the microswitch(es) on the ILS PC Board are de-actuated, turning OFF +24 VDC to the Printer Drive Circuit, the High Voltage Power Supply, and the Paper Feed Solenoid Circuits, turning OFF the +5 VDC supply voltage for the Laser Driver circuits on the Laser Unit.
Page 200 6.2.9 Laser Unit (LSU) Control Circuit The laser control signals are described below. nLDEN The LSU is activated when this output signal is LOW. If an error occurs, the nLDEN output signal level goes High and the LSU is deactivated. nVIDEO This is the actual Data Signal.
Page 201 6.2.10 Modem and Peripheral Circuit This circuit consists of Modem, DAA (Primary/Secondary) and peripheral circuit. This modem conforms to ITU-T V.34, V.33, V.17, V.29, V.27ter, V.21 channel 2 (FSK), T.4, and T.30. Modem transfers/receives data from Secondary DAA chip and serial communication. Secondary DAA chip communicates with the line through Primary DAA chip and its peripheral circuit.
Page 202 6.2.11 Receive Signal Control Circuit This circuit consists of operational DAA and its peripheral circuit. Up to this time, from Primary circuit to Secondary circuit such as Hybrid circuit, Analog circuit, Analog Front End (AFE : A-D / D-A convertor) and Modem through Line transformer, and all the Received Signals to the AFE are processed with Analog signals.
Page 203 6.2.12 Transmission Signal Control Circuit This circuit consists of operational DAA and its peripheral circuit. As the same way as the Receiving Signal Control Circuit, Modem and DAA of Secondary Circuit are con- nected. The Transmit Signals are transferred as serial data to the DAA of Primary Circuit. Therefore, there is no Analog circuit, the signal level is adjusted with internal setting of Modem.
Page 204: Line Monitor Circuit
6.2.13 Line Monitor Circuit The Line Monitor Circuit consists of an operational DAA (The secondary side chip) 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.
Page 205 6.2.14 Line Control Circuit The Line Control Circuit consists of CML relay, DP circuit, DAA (Direct Access Arrangement), Ring Detect Circuit for power-save and DC hold circuit. A Jack for an external telephone, which can be used for either an external telephone or an optional Handset Kit. The block diagram of the Line Control Circuit is shown below.
Page 206 Dial Pulse Generator The Dial Pulse Generator consists of a CML relay, a DC hold circuit, a dial pulse generate circuit and their peripheral circuits. The generator generates dial pulses. The CPU on the SC Board controls all dial pulse generation sequences.
