CHAPTER 2 OPERATION AND TIMING 1. This chapter describes the printer functions, the relationships between mechanisms and circuits, and the timing of operations. Mechanical linkages are indicated by black and white lines ( ), the flow of control signals by solid arrows ( ), and the flow of groups of signals by outline arrows ( ). 2. An active-high signal is indicated by "H" or by a signal name without a slash in front of it, such as "PSNS.
CHAPTER 2 I. BASIC OPERATION A. Functions Printer functions can be divided into five groups: the video control system, the engine control system, the image formation system, the laser/scanner system, and the paper pick-up/feed system. VIDEO CONTROL SYSTEM To external device (host computer, etc.
CHAPTER 2 B. Basic Operation Sequence The operation sequence of this printer is controlled by the microcomputer on the engine controller PCB. The purpose of each period from that the printer is turned ON until that the main motor stops rotating after completion of printing is stated below. Refer to the appendix for the detailed timing chart. Table 2-1-1 Period Purpose WAIT ( WA I T period) From power-ON until the end of To clear the drum surface of the main motor initial rotation.
CHAPTER 2 C. Power-ON Sequence The sequence from power-ON until the printer enters the STANDBY mode is as follows: 1) Power-ON 2) CPU initialization 3) Start of the video interface communication 0.5 seconds after the status command signal (/SC) turns "H", the video interface communication is ready for operation. 4) Paper jam detection and door open detection Paper detection status of the sensors and door open are detected. 5) Fixing unit-ON The fixing unit is driven for 0.5 seconds.
CHAPTER 2 II. ENGINE CONTROL SYSTEM A. Engine Controller PCB 1. Outline The operation sequence of the printer is controlled by the CPU on the engine controller PCB. When the printer is turned ON and enters the STANDBY mode, the CPU outputs signals to drive loads, such as the laser diode, motors, and solenoids, based on the pick-up command and image data input from the interface controller. A block diagram of this circuit is shown below.
CHAPTER 2 2. Operations a. CPU (IC201) The CPU intstalled in this printer is an 8-bit single-chip microcomputer. This CPU is a single-chip CPU with a built-in ROM and RAM and controls the following printer operations based on the control program stored in the ROM. 1) Printer sequence control 2) Video interface control 3) High-voltage power supply circuit control 4) Laser/scanner control 5) Sensor control 6) Control of loads such as motors, and solenoids b.

CHAPTER 2 B. Fixing Control Circuit 1. Fixing temperature control A plate-shaped fixing heater is installed in the fixing film unit to heat the fixing film. The fixing heater temperature is detected by the thermistor (TH701) on the fixing heater. As the temperature of the fixing heater rises, the resistance of TH701 drops, and the voltage of the FIXING HEATER TEMPERATURE DETECTION signal (FSRTH) decreases.
CHAPTER 2 2. Fixing heater safety circuit This circuit is located on the engine controller PCB and always monitors the abnormal rise of the fixing temperature. When the output voltage from the thermistor falls below about 0.6V (240°C) due to the elevation of the fixing heater temperature, the output of the comparator (IC302) becomes “L” and the relay (RL101) goes OFF to cut off the power to the fixing heater. 3.
CHAPTER 2 C. High-voltage Power Supply Circuit 1.
CHAPTER 2 2. Operation a. Generation of voltage applied to primary charging roller When the pick-up command is sent from the interface controller, the INITIAL ROTATION period (INTR) starts, and the PRIMARY HIGH VOLTAGE (AC) DRIVE signal (PRACC) is input to the primary high-voltage circuit via the power operational amplifier. The PRIMARY HIGH-VOLTAGE (DC) DRIVE signal (PRDCC) sent from the CPU is input to the primary high-voltage circuit.
CHAPTER 2 D. Low-voltage Power Supply Circuit 1. Outline The AC voltage input from the inlet is converted to the DC voltage in the rectification circuit, transformer, and power supply circuits, and then supplied to the printer as +24VDC, +5VDC, and +3.3VDC. When the cartridge door is opened, the door switch (SW301) is turned OFF and the +24VU supplied to the high-voltage circuit is cut OFF.
CHAPTER 2 2. Protective function The power supply circuits of +24VDC and +5VDC are equipped with overcurrent/overvoltage protective functions. These protective functions automatically shut off the output voltage to protect the circuits when overcurrent or abnormal voltage results from troubles such as a short on load.
CHAPTER 2 E. Video Interface 1. Outline Unlike the conventional video interface, which uses an individual signal line for each signal exchanged between the interface controller and engine controller, this printer uses command status. This section describes the kinds of interface signals between the engine controller and interface controller, and gives information of the sequence of printer operation using the interface signals. a. System diagram External device (host computer, etc.
CHAPTER 2 2. Operation When the power is switched ON, the printer enters the WAIT mode. When the printer is ready for operation after the WAIT period, the engine controller sends the ready status to the interface controller to notify that the printer is ready. On receiving the ready status, the interface controller sends the pick-up command to the engine controller. When the engine controller receives the pick-up command, it starts the operation of the initial rotations (INTR) sequence.
CHAPTER 2 III. LASER/SCANNER SYSTEM A. Outline The microcomputer (CPU:201) on the engine controller sends the LASER CONTROL signals (CNT0, CNT1) to the laser driver (IC801) on the laser driver PCB. The VIDEO signals (/VDO, VDO) from the interface controller are sent to the laser driver (IC801) on the laser driver PCB through the engine controller. The laser driver (IC801) emits the laser beam according to these signals sent from the engine controller and interface controller.
CHAPTER 2 B. Laser Control Circuit 1. Outline Engine controller PCB Laser driver PCB IC201 /BDI J208F-11 J801F-2 BD sensor +3.
CHAPTER 2 2. Laser diode automatic power control The laser diode automatic power control (APC) is performed by the IC801 to make the laser diode emit the laser beam at a constant intensity. The APC is performed prior to the image formation (Initial APC) and between lines (between line APC). When the CNT0 and CNT1 input to the IC801 from the CPU are “L” and “H” respectively, the sample hold circuit on the IC801 enters the sample mode (mode in which the APC is performed).
/BD Unmasking area 0 mm T2 1 mm T1 /BD Unmasking area CHAPTER 2 1 mm 1 mm Figure 2-3-3 Notes: 1. The shaded area indicates the area where the laser beam can write. 2. T1 is the range 1mm toward the center from the right and left sides of the Letter size regardless of the paper size specification. 3. T2 is the range 1mm toward the center from the leading edge of the paper (start of /BD output) to the trailing edge of the paper.
CHAPTER 2 C. Scanner System The scanner motor control circuit is shown below. Engine controller PCB Laser/scanner unit +3.
CHAPTER 2 The CPU detects the following failures and error by monitoring /BDI sent from the BD sensor, and reports it to the interface controller. 1) Scanner failure The CPU assesses a scanner failure when the /BDI cycle does not reach the specified value within 3.5 seconds after the completion of the initial forced acceleration. 2) BD failure The CPU assesses a BD failure when the /BDI is not detected within 0.
CHAPTER 2 IV. IMAGE FORMATION SYSTEM A. Outline The image formation system is the main part of the printer, and consists of the photosensitive drum, developing unit, charging roller, etc. When a pick-up command is sent from the interface controller to the engine controller, the engine controller drives the main motor to rotate the photosensitive drum, developing cylinder, primary charging roller, and transfer charging roller.
CHAPTER 2 B. Print Process The major portion of the image formation system is contained in a cartridge as shown in Figure 2-4-2. Laser beam Primary charging roller Cartridge Blade Cleaning blade Photosensitive drum Developing cylinder Static charge eliminator Transfer charging roller Figure 2-4-2 The cartridge used by the printer has a seamless photosensitive drum with the structure shown in Figure 2-4-3.

Fixing Transfer stage Figure 2-4-4 1.
CHAPTER 2 Step 1: Primary charging Primary charging roller AC bias Photosensitive drum DC bias Figure 2-4-6 For preparation of latent image formation, a uniform negative potential is applied to the photosensitive drum surface. This printer performs primary charge by the method that directly charges the photosensitive drum. The primary charging roller consists of semiconductive rubber.
CHAPTER 2 2. Developing stage The toner is applied to the electrostatic latent image on the surface of the photosensitive drum to form a visible image. This printer performs the toner projection development with a singlecomponent toner. Step 3: Development Stirrer Blade Photosensitive drum AC bias Developing cylinder DC bias Figure 2-4-8 Note: Charges in the exposed areas of the photosensitive drum are shown as positive in this figure, even though they are actually negative.
CHAPTER 2 An AC bias is applied to the developing cylinder to help project the toner particles to the drum surface and improve the contrast of the printed image. The center voltage of the AC bias (1460 Vp-p) varies with the developing DC bias. This printer changes the developing DC bias according to the IMAGE DENSITY DATA signal sent from the interface controller.
CHAPTER 2 4. Fixing stage As the toner image transferred onto the paper in the transfer stage is held to the paper only by the static electricity, even a light touch will smear the image. The toner particles are fused to the paper to make an permanent image by applying pressure and heat to the paper and the toner.
CHAPTER 2 5. Photosensitive drum cleaning stage The photosensitive drum cleaning stage is to clean the photosensitive drum surface in preparation for the next print operation to obtain crisp image. Step 7: Photosensitive drum cleaning Cleaner container Cleaning blade Photosensitive drum Sweeper strip Figure 2-4-13 Prior to the next printing, the residual toner on the drum surface is scraped away by the cleaning blade to clean the drum surface. The removed toner is collected into the cleaner container.
CHAPTER 2 V. PICK-UP/FEED SYSTEM A. Outline The printer is equipped with two pick-up sources, the multi-purpose tray and the manual feed slot. Whether or not the multi-purpose tray and the manual feed slot are loaded with paper is detected by the paper-out sensor (PS003). The main motor (M001) starts rotating in about 0.5 seconds after the engine controller receives a pick-up command from the interface controller.
CHAPTER 2 In the specified period of time after the paper reaches the paper top sensor (PS002), the engine controller sends the /BD signal to the interface controller. The interface controller sends the VIDEO signal to the engine controller based on the /BD signal to form an image on the photosensitive drum. As a result, the leading edge of the image matches with the leading edge of the paper.
CHAPTER 2 B. Jam Detection The following paper sensors are provided to detect whether paper is present and whether the paper is fed correctly: • Paper top sensor (PS002) • Paper delivery sensor (PS201) The CPU determines whether paper jam has occurred by checking for the presence of paper in the sensor at the timing stored in the CPU. If the CPU determines that a jam has occurred, it stops the print operation and notifies the jam to the interface controller. 1.
CHAPTER 2 VI. VIDEO CONTROL SYSTEM A. Interface Controller PCB 1. Outline The interface controller receives print information from external devices such as host computers through interface cables. Print information described above is dot data converted from print data, corresponding to the resource type, in the host computer. The dot data is then passed to the engine controller to control the laser diode emitting. The external devices can check the printer status using bi-directional interface.
