4-5. ATVC (Auto Transfer Voltage Control • Adjusts the transfer bias voltage based on the age and cleanliness of the transfer rollers.
5. 5-1. DRUM CARTRIDGE PC Drum • The photoconductive drum used in this printer is the organic photo conductor (OPC) type. ✽ This is the PC Drum consisting of the Charge Generating Layer and the Charge Transport Layer applied to an aluminum alloy base. Handling Precaution The PC Drum exhibits light fatigue after being exposed to light for a long time, which results in its sensitivity being changed.
5-2. PC Drum Charging • The PC Drum Charge Corona employs a comb electrode Scorotron charger system. • It generates corona emission to deposit a charge evenly across the surface of the PC Drum through a grid mesh. • The comb electrode ensures that a charge is concentrated on the grid mesh, thus reducing the amount of ozone produced.
6. LASER EXPOSURE An electrostatic latent image is formed on the surface of the PC Drum by a laser light emitted from the print head. Polygon Motor (M3) PC Drum 4131M005AB (1) FD Direction (vertical scanning direction) • The Polygon Motor and Main Motor are energized by the PRINT signal, which starts a paper take-up sequence. • The printing action in the FD direction is started when the Image Transfer Belt Positioning Sensor is activated.
(3) Print Area • The figure below shows the print area in the FD and CD direction.
7. (1) DEVELOPING UNIT Toner Cartridge Rack When printing in each of the four different colors of toner, the Toner Cartridge Rack is rotated to bring the Toner Cartridge of the corresponding color of toner (K, Y, M, or C) to the developing position. (2) Drive for the Toner Cartridge Rack • The Toner Cartridge Rack is driven by the Rack Motor (M2) and Rack Clutch.
(3) Drive for the Developing Roller • The Developing Roller is driven by the Rack Motor (M2) and the Developing Roller Drive Gears. • When the Toner Cartridge Rack is stopped at the developing position, the Developing Roller is rotated by a drive from the Rack Motor (M2) transmitted with the Developing Roller Drive Gears.
7-1. (1) Developing Position Toner Cartridge Rack Stop Position for Development • The stop position for development of each Toner Cartridge is determined by the Rack Lock Lever and the Rack Home Position Sensor (PC4). • The Toner Cartridge Rack rotates and the Rack Lock Lever drops into a stopping cutout. This unblocks the Rack Home Position Sensor (PC4), thus determining the stop position for the Toner Cartridge for the current use.
7-2. (1) Toner Cartridge Construction • The Toner Cartridge is constructed as illustrated below. 4 5 1 4131M050AA 2 1. 2. 3. 4. 5. 4131M051AA 6 3 Toper Hopper Toner Agitating Plate Toner Transport Roller Developing Roller PC Drum 7 8 6. First Regulator Blade 7. Second Regulator Blade 8.

(3) Developing Roller • Carries toner, whose amount has been regulated by the Regulator Blades. (4) Developing Bias • Applied to the Developing Roller to ensure that an adequate amount of toner is fed to the PC Drum. (5) Toner Empty Detection • Toner consumption is calculated from image data for toner empty detection.
(7) Toner Cartridge Installation Detection • Toner Cartridge installation detection is made with the Toner Cartridge Detection Sensor (PC8) and the Reflector in the Toner Cartridge.
(8) Detection of a brand new Toner Cartridge 1. A brand new Toner Cartridge is installed. 2. The Front Door is closed. Then, the Power Switch is turned ON. 3. The Toner Cartridge Rack is rotated to bring the Toner Cartridge at the developing position. 4. The Toner Cartridge Detection Sensor (PC8) detects whether or not the Toner Cartridge is installed. 5.

(3) First Image Transfer • The first image transfer bias is applied to the First Image Transfer Roller to transfer the toner image on the surface of the PC Drum onto the Image Transfer Belt. First Image Transfer Roller Image Transfer Belt First Image Transfer Bias 4131M054AA PC Drum (4) Second Image Transfer • The second image transfer bias is applied to the Second Image Transfer Roller to transfer the toner image on the Image Transfer Belt onto the paper.
(5) Second Image Transfer Roller Pressure/Retraction • The Second Image Transfer Roller is pressed against, and retracted from, the Image Transfer Belt by a cam on the printer side that is turned as the Second Image Transfer Roller Pressure Contact Solenoid (SL5) is energized or de energized.
8-2. Second Image Transfer Roller Cleaning • A reverse bias is applied to the Second Image Transfer Roller to remove any residual toner left on the roller. • The residual toner is transferred onto the Image Transfer Belt and then recovered by the Cleaning Blade. (1) Operating Timing • After the lapse of a given period of time during pre-drive. • After the paper moves past the Second Image Transfer Roller when a media error occurs. • Before the second image transfer ATVC.
8-3. (1) Image Transfer Belt Cleaning Mechanism Image Transfer Belt Cleaning Blade • The Cleaning Blade is used to scrape any residual toner off the surface of the Image Transfer Belt.
(2) Image Transfer Belt Cleaning Blade Retraction • The Image Transfer Belt Cleaning Blade is retracted from the Opposing Roller by a cam on the printer side that turns as the Belt Cleaner Separation Solenoid (SL4) is energized or deenergized. • The cam on the printer side is made into direct contact with the Cleaning Blade housing so that the Cleaning Blade is retracted.
8-4. Waste Toner Bottle • Waste toner on the PC Drum and the Image Transfer Belt is collected. • The waste toner sticking to the surface of the PC Drum is scraped off by the Cleaning Blade and conveyed by the Waste Toner Conveying Coil. • The waste toner left on the surface of the Image Transfer Belt is scraped off by the Image Transfer Belt Cleaning Blade and conveyed by the Waste Toner Conveying Coil. Cleaning Blade 4131M012AA 8-5.
9. FUSING SECTION 9-1. (1) Fusing Unit Overview • Toner transferred onto the paper through the image transfer process is permanently fixed onto the paper. • The fusing system employed in the printer is a heat roller method, in which the Fusing Roller heated by a heater lamp is pressed against the Fusing Pressure Roller and, by feeding the paper between these two rollers, toner is fused onto the paper. 4 3 7 1 2 6 5 4131M015AA 1. 2. 3. 4. 5. 6. Fusing Pressure Roller Heater Lamp (H2) 7.
(2) Drive • The Fusing Unit is driven by the Main Motor (M1). Main Motor (M1) 4131M016AA (3) Fusing Roller Pressure • The Fusing Roller and the Fusing Pressure Roller are pressed against each other at all times. They are released for maintenance service or replacement of parts. • When a paper misfeed occurs in the Fusing Unit, the Fusing Misfeed Clearing Levers are pulled upward to release pressure between the two rollers.
9-2. (1) Fusing Temperature Control Fusing Temperature Control Circuit • The resistance of the Thermistor (TH) mounted to the Fusing Roller varies with temperature. The higher the temperature, the smaller the resistance value. The output from the Thermistor (TH) is applied to the analog port of the CPU. • When the temperature increases and the resistance of the Thermistor (TH) decreases, the input voltage to the analog port becomes smaller.
(2) Fusing Temperature Control • The temperature control as detailed below is provided by means of the Fusing Roller Heater Lamp (H1) and the Fusing Pressure Roller Heater Lamp (H2). • The surface temperature of the Fusing Roller is converted by the Thermistor (TH1) to a corresponding electrical signal. 1. Warm-up Control • The temperature during the warm-up cycle is set at 170°.
10. PAPER TAKE-UP SECTION 10-1. (1) Manual Feed Tray Paper Take-Up Mechanism • The Manual Feed Tray consists of a Paper Take-Up Roll, Paper Lifting Plate, and the Manual Feed Paper Take-Up Solenoid (SL1). • When the Manual Feed Paper Take-Up Solenoid (SL1) is energized, the cam turns. At the same time, the Paper Lifting Plate raises the tray and the paper on the tray is taken up by the Paper Take-Up Roll and fed into the printer.
10-2. (1) Lower Feeder Unit (Option) Paper Take-Up Mechanism • Since there is no drive motor installed, the drive for paper take-up and transport (supplied from M1) is transmitted through a drive coupling gear from the printer. • The same paper take-up mechanism is employed as that of the Multi-Purpose Tray, except that paper separator fingers are used, instead of the separator roll with a torque limiter, for paper separation.
11. OTHER MECHANISMS 11-1. (1) Duplex Unit (Option) Drive • The drive for the Duplex Unit works as follows. The paper having a printed image on its one side is temporarily fed toward the Exit Tray and, as soon as the trailing edge of the paper moves past the guide plate before the Exit Roller, the Exit Roller is turned backward so that the paper is fed into the Duplex Unit.
