CHAPTER 5. CIRCUIT DESCRIPTION

[l] Circuit description

1. General description

The compact design of the control PWB is obtained by using Rise Processor (CPU) in the main control section and high density printing of surface mounting parts. Each PWB is independent according to its function as shown in Fig. 1.

2. PWB configuration

3. Operational description

Operational descriptions are given below:

Transmission operation When a document is loaded in standby mode, the state of the docu-

ment sensor is sensed via the CPU (SHZ). If the sensor signal was on, the motor is started to bring the document into the standby position. With depression of the START key in the off-hook state, transmission takes place.

Then, the procedure is sent out from the modem and the motor is rotated to move the document down to the scan line. In the scan processor, the signal scanned by the CIS is sent to the internal image processor and the AD converter to convert the analog signal into

binary data. This binary data is transferred from the scan processor to the image buffer within the RAM and encoded and stored in the transmit buffer of the RAM The data is then con-vetted from parallel to serial form by the modem where the serial data is modulated and sent onto the line.

Receive operation There are two ways of starting reception, manual and automatic.

Depression of the START key in the off-hook mode in the case of manual receive mode, or Cl signal detection by the LIU in the automatic receive mode.

First, the CPU(SH2) controls the procedure signals from the modem to be ready to receive data. When the program goes into phase C, the serial data from the modem is converted to parallel form in the modem interface of the 1 fax CPU(SH2) which is stored in the receive buffer of the RAM. The data in the receive buffer is decoded software-wise to reproduce it as binary image data in the image buffer. The data is DMA transferred to the recording processor within the printer control gate array which is on printer PWB and sent to the ink head. The data is printed by printer gate arrey and fine signal.

Copy operation

To make a copy on this facsimile, the COPY key is pressed when the

machine is in stand-by with a document on the document table and

the telephone set is in the on-hook state.

First, depression of the COPY key advances the document to the scan line. Similarto the transmitting operation, the image signal from

the CIS is converted to a binary signal in the DMA mode via the

reading processor which is then sent to the image buffer of the RAM. Next, the data is transferred to the recording processor in the DMA mode to send the image data to the ink head which is printed swath by swath. The copying takes place as the operation is repeated.

4) Panel PWB

The panel PWB allows input of the operation keys.

5) Printer PWB

This PWB controls the printer mechanical parts. This PWB employs Bbit CPU that is installed on printer PWB. This CPU control a printer mechanical parts.

6) LCD PWB

This PWB controls the LCD display.

7) IrDA PWB

This PWB employs led and sensor.

6)lnk sensor PWB

This PWB examine the ink level of the cartridge.

(4) Modem (Rl44EFXL) block

INTRODUCTION

The Rockwell R144EFXL MONOFAX modem is a synchronous 14400 bits per second (bps) half-duplex modem with error detection and DTMF reception. It has low power consumption and requires only a single +5V DC power supply. The modem is housed in a single VLSI device package. The modem can operate over the public switched telephone network (PSTN) through line terminations provided by a data access arrange-

ment (DAA). The R144EFXL is designed for use in Group 3 facsimile ma-chines. The modem satisfies the requirements specified in CCITT recommendations V.29, V.27 ter, V.21 Channel 2 and T.4, and meets the binary signaling requirements of T.30. The modem can operate at 14400,9600,7200,46W, 2400, or 300 bps, and also includes the V.27 ter short training sequence option. The modem can also perform HDLC framing according to T.30 at 14400, 9606,7200,4660,2400, or 300 bps. The modem features a programmable DTMF receiver and three programmable tone detectors which operate concurrently with the V.21 channel 2 receiver. The voice mode allows the host computer to efficiently transmit and receive audio signals and messages. The modem is available in either a loo-pin plastic quad flat pack (PQFP) or a 64-pin quad in-line package (QUIP). General purpose input/output (GPIO) pins are available for host as signment in the 1 W-pin PQFP.

The modem’s small size, single voltage supply, and low power con-

sumption allow the design of compact system enclosures for use in both office and home environments. MONOFAX is a registered trademark of Rockwell International.

The power unit intakes input of AC 12OV, 50/60 Hz and supplies output of +24V, +7.4V and +5V as shown in the block diagram. (See Fig. 8.)

w RECTITYING

2-1. Filter, rectifying and smoothening circuit

In the filter section, the noise generated from the power unit is elimi-

nated from being discharged to the external, and external noise is prevented from entering. Thunder or other excessive surge is prevented by the varistor 21.

In the rectifying and smoothening section, AC input is rectified by the

diodes Dl 0, 11, 12 and 13, and is smoothened by the capacitor C5. Thus, DC voltage is supplied to the switching section. Moreover, the thermistor NTCl prevents surge current when the power is turned on.

2-2. Switching section

The circuit uses the tinging choke converter of a self-excited type.

Since MOS. FETQl is repeatedly turned on and off in this system, the DC voltage

supplied from the rectifying and smoothening section is converted into the high frequency pulses. While Ql is on, energy is accumulated in the primary winding of the transformer Tl , and while Ql is off, energy is discharged to the secondary side. Thus, the power is supplied. Moreover, the frequency is varied depending on the load of the output. As the load becomes the heavier, the frequency becomes the smaller to extend the ON period.

The constant voltage is controlled by applying the feedback to the con-

trol circuit through the photo coupler PC1 from +24V output. The overcurrent-protective circuit detects that the ON period becomes the wider as the output load becomes the heavier. For the control, the OFF period is extended by the control circuit to squeeze the energy which is accumulated in the primary winding of the transformer Tl. For protection against overvoltage, the rise of the output voltage of +24V on the secondary side is brought into the overcurrent state through the continuity of the power zener diode D104 between +24V output and GND. Thus, the overcurrent-protective circuit of the control circuit is activated for the protection.
