Figure 1-3-1 B. Toner Caution The toner is non-toxic substance composed of plastics and minute color pigments. If toner adheres to the skin or clothing, remove as much as possible with dry tissue first, then wash with cold water, Hot water should not be used, as the toner will solidify and become difficult to remove. Toner will easily decompose vinyl materials, therefore avoid the toner to come close to vinyl. C. Ozone Safety An infinitesimal amount of ozone gas (O3) is generated during corona discharge from the charging roller. The ozone gas is emitted only while the printer is operating. This printer meets the ozone emission reference value set by Underwriters Laboratory (UL) at the time it is shipped from the factory.

V. INSTALLATION

A. Precautions This product has been carefully adjusted and strictly inspected before packing and shipping. To make the operation as intended, it is important to install it correctly. Service engineers must understand the performance of the printer sufficiently, install it in the appropriate environment with proper procedures, and operate the necessary checks. The following requirements must be met when installing the printer. The service engineer should inspect the installing site before taking the printer to the customers premises. Power must be directly connectable to a single socket with a supply voltage within 10 % of the rated voltage (110-127V) or +6 % to -10 % of the rated voltage (220-240V.) The temperatures should be in a range from 10 to 32.5 C and the relative humidity from 20 to 80 %. Avoid areas closed to water faucets, boilers, humidifiers, or refrigerators. Avoid areas near open flames, dusty locations, windy locations, areas which emit ammonia gas, and areas directly exposed to sunlight. When exposure to direct sunlight is unavoidable, hanging curtains is recommended. The room should be well ventilated. The printer should be placed on a level surface. If the printer is set up on a desk, be sure a study desk is used. Set the printer at a suitable distance from the wall for easy operation (See Figure 1-5-1.) There must be enough space around the printer to operate. Following dimensions should be taken into consideration to select an installation space for the printer.

Figure 2-2-4 2. Fixing Heater Safety Circuit This circuit is installed 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 0.67V (244C) due to the elevation of the fixing heater temperature, the output of the comparator (IC302) becomes L and the relay (RL101) goes OFF, cutting off power to the fixing heater.
3. Protection function The printer contains the following three protective functions in order to prevent excursion of the fixing heater. The CPU monitors the voltage of TH701. When detecting an abnormality, the CPU assesses a fixing heater failure and sets the FIXING HEATER DRIVE signal (FSRD) to L and the /RLYD signal to H as to turn OFF the relay (RL101), shutting off power to the fixing heater. At the same time, the CPU notifies the failure to the interface controller. When the fixing heater temperature rises abnormally and the thermal fuse exceeds 228C, the thermal fuse melts, cutting off the power supply to the fixing heater. When the fixing temperature rises abnormally and the voltage of TH701 falls below about 0.67V (244C equivalent), the fixing heater safety circuit interrupts the power supply to the fixing heater regardless of the output from the CPU. 4. Detecting Fixing Heater Error The CPU assesses fixing heater failures and notifies the failure to the interface controller under the following conditions: a. Within 500 msec after the start of the initial temperature control, the temperature does not reach 20C. b. During the fixing heater temperature control, the temperature remains above 250C for more than the specified period of time. c. During the print or warm-up period, the temperature does not reach 100C, even though the power has been supplied for the specified period of time. d. After the 500-msec fixing heater temperature control at the powering-ON, the CPU starts the normal temperature control and monitors the temperature every 135 msec. During this normal temperature control, the temperature sequentially drops to less than 20C twice. e. During the normal temperature control, the fixing heater temperature falls below 100C for the specified period of time. Note: The fixing film may be damaged if rotated at a temperature of 100C or below due to the high oil viscosity. Therefore, the fixing heater is required to rise above 100C as to melt the oil before rotated.

2. Operation a. Primary Charging Roller Voltage Generation When the pickup 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. Meanwhile, the PRIMARY HIGH-VOLTAGE (DC) DRIVE signal (PRDCC) is output from the CPU and input to the primary high-voltage circuit. This generates and combines AC bias and DC bias. The combined primary high-voltage is applied to the primary charging roller. The IC302 compares the primary high-voltage (DC) with the PRIMARY HIGH-VOLTAGE (DC) DRIVE signal (PRDCC) sent from the CPU in order to control the primary high voltage (DC). The presence of the cartridge is detected by the CPU. If the CPU detects the current flow (CRGSNS) on the J304, it determines the presence of the cartridge. b. Developing Bias Generation The DEVELOPING BIAS (AC) DRIVE signal (DVACC) is input to the developing bias circuit via the power operational amplifier, causing the circuit to generate the AC bias. Meanwhile, the developing DC bias is generated in the DC generation circuit on the developing bias circuit. The AC bias and DC bias are combined and applied to the developing cylinder. c. Transfer Charging Roller Voltage Generation The transfer charging roller is applied with the negative bias, print bias, and between-page bias according to the print sequence. The negative bias (negative voltage) cleans the roller by moving the toner adhering to the roller to the photosensitive drum. A negative voltage is applied to the roller at the specified timing. The print bias (positive voltage) transfers the toner on the photosensitive drum onto the paper. A voltage is applied to the roller. The between-page bias prevents the residual toner on the photosensitive drum from adhering to the transfer charging roller. A positive voltage lower than the print bias is applied to the roller at the specified timing. When the interface controller outputs a pickup command, the INITIAL ROTATION period (INTR) starts. At the same time, the CPU outputs the TRANSFER NEGATIVE VOLTAGE DRIVE signal (TRNFOT). This applies negative bias to the transfer charging roller for the specified period of time as to clean the roller. During the print sequence, the CPU outputs the TRANSFER POSITIVE VOLTAGE DRIVE signal (TRPWM) in order to apply the print bias and between-page bias to the transfer roller. After printing is completed, the negative bias is applied again to clean the transfer charging roller. d. Fixing Bias Generation The CPU outputs the PRIMARY HIGH-VOLTAGE (DC) DRIVE signal (PRDCC), causing the DC generation circuit on the primary high-voltage circuit to output the primary DC bias. The negative DC voltage is applied to the pressure roller as the fixing bias. e. Cartridge Detection When the PRIMARY HIGH-VOLTAGE (AC) DRIVE signal (PRACC) is output from the CPU and then the primary AC bias is output from the AC generation circuit on the primary high-voltage circuit, the primary high-voltage circuit feeds back the CARTRIDGE DETECTION signal (CRGSNS) to the CPU. During WAIT period, the CPU checks the voltage of the CRGSNS signal at the timing the primary AC bias is output, in order to detect the presence or absence of the cartridge.

3. Cleaning Page The printer executes a cleaning page sequence by the command sent from the interface controller. The cleaning page cleans the pressure roller. Receiving a cleaning page execution command from the interface controller, the engine controller conducts the paper pickup operation. Then, the engine controller adjusts the fixing temperature at 200C and feeds the paper 4mm at a time by step-driving the main motor. This fuses the toner adhering to the pressure roller and moves it to the paper. Note: The paper used for the cleaning page must be the maximum width in the scanning direction (indicated in the specifications) and 240 mm or more in the feeding direction.
4. Thick Paper Mode The printer contains a thick paper mode and a thick paper H mode. This mode is activated by a command sent from the interface controller. The mode is effective until a command for the other paper mode is sent from the interface controller. The thick paper mode implements the following controls: Rises the fixing heater target temperature : higher than usual (in the plain paper mode). Delays the paper pickup timing for the first page : 5.5 seconds later than usual. A delay is introduced to the pickup timing between 4 and 24 sec to suit the number of prints and selected mode: if A4 and a delay of 4 sec, 6 ppm. if A4 and a delay of 24 sec, 2 ppm.

III. LASER/SCANNER SYSTEM
A. Outline The printer contains a laser driver (IC801) on its laser driver PCB. The microcomputer (CPU : IC201) on the engine controller sends the LASER CONTROL signals (CNT0, CNT1) to the IC801. Meanwhile, the interface controller sends the VIDEO signals (/VDO, VDO) to the IC801 through the engine controller. The IC801 emits laser diode based on these signals sent from the engine controller and interface controller. The laser beam emitted form the laser diode passes though the collimator lens and cylindrical lens, and then strikes the four-faced scanning mirror rotating at a constant speed. Then, the beam reflects off the scanning mirror, passes through the focusing lens, and strikes the reflective mirror. The beam reflects off the reflective mirror and finally, scans onto the photosensitive drum. The photosensitive drum rotates at a constant speed, and at the same time, the laser beam scans across the drum surface at a constant speed. This allows the laser beam to form a latent image on the drum surface.

Figure 2-3-2 The CPU controls a switching operation for the following four modes: standby, APC emitting, masking, and unmasking. The CPU switches these modes by sending the LASER CONTROL signals (CNT0, CNT1) to the laser driver (IC801) on the laser driver PCB. When both CNT0 and CNT1 signals are L, the IC801 enters the standby mode to reset the laser driver PCB. When CNT0 and CNT1 signals are L and H respectively, the IC801 enters the APC emitting mode to make the laser diode emit the laser beam. The laser driver also performs the Auto Power Control, stated in the following section. When both the CNT0 and CNT1 signals are H, the IC801 enters the masking mode. Regardless of the VIDEO signals (VDO, /VDO), the IC801 prohibits the laser diode from emitting laser beams. When the CNT0 and CNT1 signals are H and L respectively, the IC801 enters the unmasking mode to turn the laser ON and OFF according to the VDO, /VDO signals sent from the interface controller.

2. Laser Diode Automatic Power Control The laser diode automatic power control (APC) is performed by the IC801. The APC makes the laser diode emit laser beams at a constant intensity. It is performed prior to the image formation (Initial APC) and during the between-line (between line APC). When the CNT0 and CNT1 signals, input to the IC801 from the CPU, are L and H respectively, the IC801 makes the sample hold circuit enter the sample mode (mode in which the APC is performed). At the same time, the IC801 allows the laser diode (LD) to emit laser beams. The intensity of the laser beam is detected by the photo diode (PD), converted into voltage, and then fed back to the IC801. To control the laser intensity, the IC801 maintains the fed-back voltage equal to the reference voltage by increasing or decreasing the drive current for the laser diode. When the CNT0 signal goes H, the IC801 makes the sample hold circuit enter the hold mode. In this mode, the IC801 converts the laser intensity controlled by the APC to voltage and stores it in the hold condenser (C803). 3. Horizontal Synchronization Control The CPU controls the horizontal synchronization based on the HORIZONTAL SYNCHRONOUS INPUT signal (/ BDI) sent from the BD sensor in the laser scanner. The CPU turns CNT0 and CNT1 signals to L and H respectively, making the laser diode emit a laser beam at the specified timing based on the /BDI signal. The laser beam passes through the collimator lens and cylindrical lens, and strikes the four-faced scanning mirror. Then, the laser beam reflects off the scanning mirror, passes through the BD lens on the scanning light path, and enters the BD sensor. Detecting the laser beam, the BD sensor generates the HORIZONTAL SYNCHRONOUS signal (/BD) based on the /BDI signal and then sends it to the interface controller. 4. Image Masking Control The CPU performs the image masking control in order to prevent the laser diode from emitting in the non-image area. In this control, the CPU controls the period of the laser diode emission by conducting the CNT0 and CNT1 signals that are sent to the IC801. In the non-image area, the CPU sets the CNT0 and CNT1 signals H as to implement the image masking. The IC801 prohibits the laser diode from emitting regardless of the video signals (VDO, /VDO) sent from the interface controller. In the image masking area, the CPU sets the CNT0 signal H and CNT1 signal L. as to stop the image masking. The IC801 turns the laser ON and OFF according to the VDO, /VDO signals sent from the interface controller.

Figure 2-4-4 1. Electrostatic Latent Image Formation Stage This stage consists of two steps which form an electrostatic latent image on the photosensitive drum. At the end of this stage, areas not exposed to laser (dark areas) hold the negative charges. Areas exposed to laser (light areas) loose the negative charges. The image formed on the drum with the negative charges is invisible to eyes, which is called an electrostatic latent image.

Step 1: Primary charging
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. Primary charging of this printer is performed by the method that directly charges the photosensitive drum. The primary charging roller consists of semiconductive rubber. In addition to DC bias, AC bias is applied to the primary charging roller to maintain the potential on the drum surface uniform. The DC bias changes with the developing DC bias that changes according to the IMAGE DENSITY DATA signal sent from the interface controller. This direct charging method has advantages such as the lower applied voltage and almost no ozone generation over the conventional corona charging method. Step 2: Scanning Exposure When the laser beam scans onto the photosensitive drum surface, charges on the light area are neutralized to form an electrostatic latent image.

2. Developing Stage Toner is applied to the electrostatic latent image on photosensitive drum surface to form a visible image. This printer performs the toner projection development with a single-component 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. It means that the photosensitive drum potential is higher as compared with that of cylinder.
As shown in Figure 2-4-8, the developing unit consists of a developing cylinder and rubber blade. The developing cylinder consists of a fixed magnet and a cylinder which rotates around the magnet. The single-component toner mainly consists of magnetite and resin binder and is held to the cylinder by magnetic attraction. The toner functions as an insulator, and acquires a negative charge by friction due to the rotating cylinder. The areas on the drum that were exposed to the laser beam have a higher potential (are less negative) than the negatively charged toner particles on the developing cylinder. When these areas approach the toner layer of the cylinder (with negative charges), the potential difference (higher on the drum) projects the toner particles to them. This is called toner projection development, which develops the latent image on the drum into a visible image.
