Page 147: Overview/Configuration
Chapter 8 8.1 Overview/Configuration 8.1.1 Overview 0019-5012 The image formation system forms a toner image on paper, which is controlled by the DC controller. It consists of four toner cartridges and the ETB unit, etc. The DC controller controls the laser scanner unit, and forms an electrostatic latent image on the photosensitive drum based on the video signal received from the main controller.
Page 148: Print Process
Chapter 8 8.1.2 Print Process 0019-5013 The print process is performed in 10 steps with five blocks. A toner image is formed on paper when the steps in each block are executed in sequence. 1. Electrostatic latent image formation block To form an electrostatic latent image on the photosensitive drum Step 1: Pre-exposure Step 2: Primary charging...
Page 149 Chapter 8 8.1.3 Electrostatic Latent Image Formation Block 0019-5014 In this block, an electrostatic latent image is formed on the photosensitive drum by following three steps. When a laser beam scans the photosensitive drum charged with a negative potential, an image with negative charge is formed on the photosensitive drum. This image is called "an electrostatic latent image"...
Page 150: Development Block
Chapter 8 8.1.4 Development Block 0019-5015 In this block, toner is adhered to the electrostatic latent image on the photosensitive drum to make it visible by the contact development method. In the contact development method, the developing cylinder is closely engaged with the photosensitive drum. Development is performed when toner is transferred from the developing cylinder to the photosensitive drum.
Page 151 Chapter 8 Step 6: Transfer The toner on the photosensitive drum is transferred to paper. The transfer roller is located at the opposite side of the photosensitive drum across the ETB. A positive DC bias is applied to the transfer roller. Since the ETB is charged positive by the transfer roller, the negative-charged toner on the photosensitive drum is transferred to the paper.
Page 152: Fixing Block
Chapter 8 8.1.6 Fixing Block 0019-5017 In this block, a toner image is fixed on paper. The toner image transferred to the paper can be smeared easily by hands since it is only attracted to the paper by a static electricity. When pressure and heat are applied to the paper and toner image, the toner image melts with mixed colors and becomes a permanent printed image (on-demand fixing).
Page 153: Image Stabilization Control
Chapter 8 8.2 Image Stabilization Control 8.2.1 Overview 0019-5019 The quality of a printed image is affected by changes in environmental condition where the machine is installed or changes in the characteristics of the photosensitive drum and toner. The machine performs the following controls according to necessity to stabilize print operation. - Environmental change corrective control To correct values of primary charging biases and developing biases based on the result of detection performed by the environment sensor.
Page 154: Environmental Change Corrective Control
Chapter 8 8.2.2 Environmental Change Corrective Control 0019-5020 This control corrects values of primary charging biases and developing biases to obtain an optimum image under the detected environmental condition. Explanation of operation The environment sensor sends detected temperature and humidity to the DC controller as a temperature signal and a humidity signal. The DC controller detects the printer's installation environment based on these two signals.
Page 155: D-Half Control
Chapter 8 8.2.3 D-half Control 0019-5021 This control corrects the gradation data based on the halftone density in order to obtain ideal image gradation. The DC controller executes this control following the command sent from the main controller. Explanation of operation 1) When receiving a command of executing density measurement from the main controller, the DC controller forms a pattern image for image gradation correction for each color on the ETB.
Page 156 Chapter 8 A pattern image for image gradation correction Image gradation correction pattern is formed on the position away from ETB center to right and left in the following order. ETB 1st round 1) Pattern image for adjustment of LED light intensity Y, C, M pattern is printed on the left side only.
Page 157: Color Displacement Corrective Control
Chapter 8 8.2.4 Color Displacement Corrective Control 0019-5022 This control corrects color displacement which occurs due to individual difference of the laser scanner unit and toner cartridge. Since this machine uses a different toner cartridge for each color, a difference may occur in the position or the size of an image depending on the color. The machine performs correction by calculating the degree of color displacement based on the position of the pattern image for color displacement correction formed on the ETB and controlling a video signal for each color.
Page 158 Chapter 8 Error Codes: E020 Warning: color displacement/density sensor abnormality When light could not be received by the light receiver, the machine sets an initial value for the color displacement corrective value, and displays the error code on the control panel. Pattern image for color displacement correction The pattern images are formed on both sides of the ETB certain distance away from the center in the following order.

Page 161: Toner Level Detection
Chapter 8 8.3.2 Toner Level Detection 0020-8176 The machine uses a transparent toner level detection method. With this method, light goes through the toner cartridge while the toner is stirred driven by the drum motor. The DC controller detects the toner level by monitoring how long it takes for the light to go through the cartridge. Explanation of operation The DC controller illuminates the LED on the memory controller PCB.
Page 162: New Toner Cartridge Detection
Chapter 8 8.3.5 New Toner Cartridge Detection 0020-0794 It is detected whether the protection material has been removed from the new cartridge.

Page 164: Transfer Unit
Chapter 8 8.4 Transfer Unit 8.4.1 ETB Unit 0019-8976 The ETB unit transfers toner into paper while feeding the paper. The ETB unit consists of the ETB, ETB tension roller, ETB feed roller, ETB slave roller, attraction roller, and transfer roller. The ETB motor (M5) rotates the ETB feed roller, and this drive rotates the ETB.
Page 165: Automatic Bias Control
Chapter 8 8.4.2 Automatic Bias Control 0019-8977 Depending on the individual difference or deterioration condition of the transfer roller, attraction roller, and ETB, differences and changes occur in the resistance value of each unit. In this condition, a transfer failure may occur when an expected level of bias is not applied to each roller. This control is executed to apply the optimum level of bias to each roller based on the measured voltage of each roller.
Page 166: Etb Cleaning
Chapter 8 8.4.3 ETB Cleaning 0019-8978 The ETB is used not only to transfer the toner on the photosensitive drum to the paper but also to write a pattern image for correction for image stabilization control. If the toner which is not transferred to the paper remains on the ETB, it causes stain on the back of paper. In this control, the ETB surface is cleaned by placing the residual toner on the ETB back to the photosensitive drum electrostatically.
Page 167: Transfer Roller Engagement/Disengagement Control
Chapter 8 8.4.4 Transfer Roller Engagement/disengagement Control 0019-8979 Overview In the machine, the transfer roller is engaged with or disengaged from the photosensitive drum via the ETB to reduce the color photosensitive drum consumption at monochrome printing.

Page 185: Overview/Configuration
Chapter 9 9.1 Overview/Configuration 9.1.1 Overview 0019-5027 The pickup/feed system picks up and feeds paper. The machine has two pickup inlets; a cassette and a manual feed tray, and the paper is delivered to the delivery tray. The pickup/feed system consists of the motor, solenoid, and feed roller, etc. The reverse unit and duplexing feed assembly are controlled by the reverse driver PCB.
Page 186 Chapter 9 The cassette detection switch (SW2) detects the presence/absence of the cassette. The manual feed paper sensor (SR707) and the cassette paper sensor (SR709) detect the presence/absence of the paper in the manual feed tray and the cassette. The reverse sensor (SR706), pre-registration sensor (SR708), registration sensor (SR710), paper loop sensor (SR6001), and fixing delivery sensor (SR6005) detect the arrival and passage of the paper on the feed path.
Page 187: Interval Speed Increase Control
Chapter 9 9.1.2 Interval Speed Increase Control 0020-8556 To increase printing speed, the machine increases the speed in an interval which does not affect image formation. The DC controller increases the process speed four times faster when the paper is fed to the reverse assembly. It also increases the process speed of duplex printing four times faster at the duplex feed assembly.
Page 188: Other Control
Chapter 9 9.2 Other Control 9.2.1 Cassette Pickup Mechanism 0019-5028 The cassette pickup is a mechanism to pick up and feed the paper loaded in the cassette into the machine one by one. The pickup condition is detected by the following sensors or switch. - Cassette detection switch (SW2): Detects the presence/absence of the cassette.
Page 189: Manual Feed Pickup Mechanism
Chapter 9 9.2.2 Manual Feed Pickup Mechanism 0019-5029 The manual feed pickup is a mechanism to pick up and feed the paper loaded on the manual feed tray into the machine one by one. The pickup condition is detected by the following sensors or switch. - Cassette detection switch (SW2): Detects the presence/absence of the cassette.
Page 190: Skew Correction
Chapter 9 9.2.3 Skew Correction 0019-5030 Before the paper fed from the cassette or manual feed tray is transported to the ETB unit, a skew is corrected. 1) The fed paper comes into contact with the registration shutter at the registration roller assembly. The lead edge of the paper comes into contact with the registration shutter so that the right and left edges of the paper are aligned.
Page 191: Throughput-Down Control
Chapter 9 9.2.4 Throughput-down Control 0020-0387 The machine prevents an abnormal temperature increase at the edge of the fixing sleeve by increasing an interval between sheets while keeping the paper feeding speed as needed. Control of the fixing assembly is performed to keep the temperature of the fixing heater higher than the target temperature while the paper is transported so that the target fixing temperature is maintained (print temperature control).
Page 192: Feeding Speed Control
Chapter 9 Print speed when the throughput down control is executed When the throughput down control is ON, print speed is switched step by step depending on the paper type or the temperature on the edge of the fixing sleeve etc. Following shows the print speed list in case of the minimum throughput.
Page 193: Delivery
Chapter 9 9.2.7 Delivery 0020-0766 Delivery is a mechanism to deliver the paper transported from the fixing assembly to the delivery tray. The following sensors detect the paper condition. - Fixing delivery sensor (SR6005): Detect the paper delivered from the fixing unit. - Reverse sensor (SR706): Detect the paper transported to the reverse assembly.
Page 194 Chapter 9 5) The paper is transported to the delivery tray by the delivery roller. Since the duplexing/delivery flapper is turned down at this point, the feed path toward the duplexing feed assembly is closed. Whether or not the paper has been delivered to the delivery tray is detected by the delivery sensor (SR715). When the paper in the delivery tray reaches the full level, the delivery paper full-level flag comes into contact with the paper, and the full level is detected by the delivery paper full-level sensor (SR713).
Page 195: Detection Jams
Chapter 9 9.3 Detection Jams 9.3.1 Jam Detection Outline 9.3.1.1 Overview 0019-5034 The machine is provided with several paper sensors at specified positions on the feed path to detect whether the paper exists or whether the paper is transported normally or not. When the machine determines that a jam has occurred based on the result of detection performed by each sensor, it stops print operation and displays an error mes- sage indicating that a jam occurred on the control panel at the same time.
Page 196: Stationary Jams
Chapter 9 9.3.3 Stationary Jams 9.3.3.1 Pickup Stationary JAM 0019-5039 The machine determines that the pickup stationary jam has occurred when the registration sensor (SR710) cannot detect the trailing edge of the paper even when approximately 3.2 seconds elapsed after it detected the lead edge of the paper. 9.3.3.2 Delivery Stationary JAM 0019-5040 The machine detects the delivery stationary jam after determining that the wrapping jam did not occur.
Page 197: Duplex Feeding
Chapter 9 9.4 Duplex Feeding 9.4.1 Overview 0019-8980 The paper fed from the fixing assembly to the reverse unit is sent to the reverse assembly. When delivery is performed, the paper is transported to the delivery tray. When duplexing printing is performed, the paper is sent to the duplexing feed assembly where transfer and fixing are performed for the second side.
Page 198: Duplexing Feed Control
Chapter 9 9.4.2 Duplexing Feed Control 0019-8981 In duplexing printing, the machine reverses the paper printed on the first side and again transports it to the pickup position to print the second side. Paper reverse is driven by the reverse motor (M11) and duplexing solenoid (SL5017). The duplexing feed assembly feeds the paper by rotating two skew rollers by the duplexing feed motor (M10).
Page 199 Chapter 9 Duplexing feed sequence 1) The feed roller driven by the fixing motor (M1) delivers the paper in which fixing was performed on the first side from the fixing unit. 2) When a specified period of time elapses after the fixing delivery sensor (SR6005) detects the lead edge of the paper, the duplexing feed motor (M10) and the reverse motor (M11) rotate forward.
Page 200 Chapter 9 5) When a specified period of time elapses after the reverse motor rotates in reverse, the duplexing solenoid (SL5017) is turned ON. When the duplexing/delivery flapper moves up, the feed path toward the duplexing feed assembly is secured. The paper is transported through the duplexing feed assembly.
