CHAPTER II -3 1.3 Main PCB 1.3.1 CPU Core Fig. 2.3. shows the CPU circuit block on the main PCB. The CPU is an IDT 79R3041-20J which is driven at a clock frequency of 20MHz. This clock frequency is made by dividing the source clock frequency of 40.0MHz by two.
CHAPTER II -4 1.3.2 ASIC The ASIC is composed of a Cell Based IC that contains the following functional blocks. (1) Oscillator circuit Generates the main clock for the CPU by dividing the source clock frequency by two. (2) Address Generator Generates the address bus by latching the AD bus with the ALE signal.
CHAPTER II -5 (8) Parallel I/O <Data receive Mode> There are two modes in this unit. One is the CPU receive mode and the other is the DMA receive mode. In the CPU receive mode the CPU receives the command data from the PC, and after the CPU is switched to the DMA mode, it receives the image data and writes it to the DRAM directly.
CHAPTER II -6 (12) Engine control I/O This I/O is used for the connection to the driver PCB. It controls the main motor, solenoid, sensors, etc. Fig. 2.
CHAPTER II -7 1.3.3 ROM The program and the font data are stored in 4Mbytes of ROM. The ROM is composed of two 16Mbit masked ROMs which are mounted in 42-pin IC sockets. Fig. 2.5 1.3.4 Optional ROM The program and the font data are stored in 4Mbytes of ROM.
CHAPTER II -8 1.3.5 DRAM Four 4Mbit DRAM (x 8bit) are used as the printer memory. Fig. 2.7.
CHAPTER II -9 1.3.6 Optional RAM A 32bit SIMM (72 pin) can be fitted as optional RAM. The main PCB has one slot and its capacity is for SIMM from 1Mbytes to 32Mbytes.
CHAPTER II -10 1.3.7 Optional Serial I/O The interrupt of the serial I/O is input to the EXINT terminal of the ASIC, and recognized by the CPU. A 32-byte space for a register is provided for this I/O, which is read and written to by the CPU. Fig. 2.9 1.
CHAPTER II -11 1.3.9 Reset Circuit The reset IC is a PST591DMT. The reset voltage is 4.2V (typ.) and the LOW period of the reset signal is 50ms (typ.).
CHAPTER II -12 1.3.11 Engine I/O Fig. 2.13 shows the engine interface circuit. Fig. 2.13.

CHAPTER II -17 2.2 Paper Transfer 2.2.1 Paper Supply The pick-up roller picks up one sheet of paper from the paper feeder every time it is rotated and feeds it to the paper feed roller. Fig. 2.19 The paper is gripped between the pick-up roller and the separation pad and separated into individual sheets.
CHAPTER II -18 2.2.3 Paper Eject The completion of paper eject is detected in the following manner: (a) When the leading edge of the paper pushes down the eject sensor actuator located in the fixing unit, the photo sensor (photo interrupter) is opened and detects the start of paper eject.
CHAPTER II -19 2.3 Sensors 2.3.1 Cover Sensor Detects opening and closing of the top cover. Fig. 2.23 2.3.2 Toner Empty Sensor Detects if there is toner in the toner cartridge. It also detects whether or not the drum unit is installed. (The toner cartridge is installed in the drum unit).
CHAPTER II -20 2.4 Drum Unit 2.4.1 Photosensitive Drum Generates the latent electrostatic image and develops the image on the drum surface. 2.4.2 Primary Charger Forms a uniform charge on the drum surface. (1) Corona wire Generates the ion charge on the drum.
CHAPTER II -21 2.5.2 Exposure Stage After the drum is positively charged, it is exposed to the light emitted from the laser unit. Fig. 2.26 The area exposed to the laser beam is the image to be printed. The surface potential of the exposed area is reduced forming the electrostatic image to be printed.
CHAPTER II -22 2.5.3 Developing Developing causes the toner to be attracted to the electrostatic image on the drum so as to transform it into a visible image. The developer consists of a non-magnetic toner. The development roller is made of conductive rubber and the supply roller which is also made of conductive sponge rotate against each other.
CHAPTER II -23 2.5.5 Drum Cleaning Stage In the image transfer stage, not all the toner on the photosensitive drum is transferred onto the paper but some remains on the drum.
