High voltage power supply The high-voltage power supply delivers the high-voltage biases to the following components used to transfer toner during the image-formation process: ● Primary-charging roller (in the cartridge) ● Developing roller (in the cartridge) ● Primary-transfer roller ● Secondary-transfer roller Figure 1-4 High voltage power supply circuits Y M C K The high voltage power supply contains several separate circuits.
Table 1-8 High voltage power supply circuits (continued) ENWW Circuit Description Primary-transfer-bias generation DC positive bias transfers the latent toner image from each photosensitive drum onto the ITB. Secondary-transfer-bias generation Two DC biases, one positive and one negative, transfer the toner from the ITB onto the paper.
Low voltage power supply The low-voltage power-supply circuit converts the AC power from the wall receptacle into the DC voltage that the product components use. The product has two low-voltage power-supplies for 110 Volt or 220 Volt input.
Table 1-9 Converted DC voltages Main DC voltage Sub-voltage Behavior Notes +24 V +24VA Stopped during Sleep (powersave) mode The 24V POWER SUPPLY (24VRMT) signal controls supply or interruption of +24VA. +24VB Interrupted when the front door or right door open Stopped during Sleep (powersave) mode +5 V +5VA Supplied during Sleep (powersave) mode 2 and Sleep (powersave) mode 3 The VOLTAGE CONVERSION (PWRSAVE) signal converts output voltage of +5VA into 3.2V.
Overcurrent/overvoltage protection The low-voltage power supply stops supplying the DC voltage to the product components whenever it detects excessive current or abnormal voltage from the power source. The low-voltage power supply has a protective circuit against overcurrent and overvoltage to prevent failures in the power supply circuit. If the low-voltage power supply is not supplying DC voltage, the protective function might be running. In this case, turn the power off and unplug the power cord.
Power off condition The DC controller turns off the product with the 24V POWER SUPPLY (24VRMT) signal, 5V POWER SUPPLY (VC5VOFF) signal, 3V POWER SUPPLY (VC3VOFF) signal, and VOLTAGE CONVERSION (PWRSAVE) signal. +5VA and +5VC, are converted into +3.2V, and +3.3VA and supplied during the power off condition. Fuser control The fuser-control circuit controls the fuser temperature. The product uses an on-demand fusing method.
Fuser temperature control circuit The temperatures of the two rollers in the fuser fluctuate according to the stage of the printing process. The DC controller sends commands to the fuser-control circuit to adjust temperatures.
Fuser over temperature protection To protect the fuser from excessive temperatures, the product has four layers of protective functions. If one function fails, the subsequent functions should detect the problem. ● ● DC controller: When a thermistor or thermopile detects a temperature above a certain threshold, the DC controller interrupts power to the specific heater.
Fuser failure detection When the DC controller detects any of the following conditions, it determines that the fuser has failed. The DC controller then interrupts power to the fuser heaters and notifies the formatter.
Laser/scanner system The laser/scanner system forms the latent electrostatic image on the photosensitive drums according to the VIDEO signals sent from the formatter. The product has two laser/scanners: one for yellow and magenta and the other for cyan and black. The formatter sends the DC controller instructions for the image of the page to be printed. The DC controller signals the lasers to emit light, and the laser beams pass through lenses and onto the scanner mirror, which rotates at a constant speed.
The DC controller determines that a laser/scanner has failed when any of the following conditions occurs: 20 ● Laser failure: The detected laser intensity does not match a specified value when the product initializes. ● Beam-detect (BD) failure: The BD interval is outside a specified range during printing. ● Scanner-motor failure: The scanner motor does not reach a specified rotation speed within a certain time after it begins rotating.
Image formation system The image-formation system creates the printed image on the paper. The system consists of the laser/ scanners, print cartridges, imaging drums, ITB, and fuser.
Image formation process The image-formation system consists of ten steps divided into six functional blocks. Figure 1-10 Image formation process Fusing Fuser Y M C K Table 1-11 Image formation process Functional block Steps Description Latent image formation 1. Pre-exposure An invisible latent image forms on the surface of the photosensitive drums. 2. Primary charging 3. Laser-beam exposure Development 4. Development Toner adheres to the electrostatic latent image on the photosensitive drums.
Step 1: Pre-exposure Light from the pre-exposure LED strikes the surface of the photosensitive drum to remove any residual electrical charges from the drum surface. Figure 1-11 Pre-exposure Step 2: Primary charging The primary-charging roller contacts the photosensitive drum and charges the drum with negative potential.
Step 3: Laser-beam exposure The laser beam strikes the surface of the photosensitive drum in the areas where the image will form. The negative charge neutralizes in those areas, which are then ready to accept toner. Figure 1-13 Laser-beam exposure Step 4: Development Toner acquires a negative charge as the developing cylinder contacts the developing blade.
Step 5: Primary transfer The positively charged primary-transfer rollers contact the ITB, giving the ITB a positive charge. The ITB attracts the negatively charged toner from the surface of each photosensitive drum, and the complete toner image transfers onto the ITB, beginning with yellow, followed by magenta, cyan, and black.
Step 7: Separation The stiffness of the paper causes it to separate from the ITB as the ITB bends. The static-charge eliminator removes excess charge from the paper to ensure that the toner fuses correctly. Figure 1-17 Separation Step 8: Fusing To create the permanent image, the paper passes through heated, pressurized rollers to melt the toner onto the page.
Step 9: ITB cleaning The cleaning blade scrapes the residual toner off the surface of the ITB. The residual toner feed screw deposits residual toner in the toner collection box. Figure 1-19 ITB cleaning Step 10: Drum cleaning Inside the print cartridge, the cleaning blade removes residual toner from the surface of the drum to prepare it for the next image. The waste toner falls into the hopper in the print cartridge.
The DC controller rotates the drum motor to drive the photosensitive drum, developing roller, and the primary-charging roller. Figure 1-21 Print-cartridge system The DC controller rotates the drum motor to drive the photosensitive drum, developing unit, and primary charging roller. The memory tag is a non-volatile memory chip that stores information about the usage for the print cartridge.
The DC controller notifies the formatter of an error if any of the following conditions exist: ● The memory tag fails to either read to or write from the DC controller ● The RD sensors detect a missing or incorrectly installed print cartridge. ● The accumulated print time reaches a specified time period or the cartridge runs out of toner.
The DC controller rotates the developing disengagement motor and changes the direction of the cam according to the instructions from the formatter for each print job. When the product is turned on and at the end of each print job, all four of the developing rollers disengage from the photosensitive drums. If the next print job is full-color mode, each of the developing rollers engage. If the next print job is black-only mode, only the black developing roller engages.
Intermediate transfer belt (ITB) unit The ITB unit accepts the toner images from the photosensitive drums and transfers the completed image to the paper. The ITB unit has these main components: ● ITB ● ITB drive roller ● ITB-driven roller ● Primary-transfer rollers ● ITB cleaner The ITB motor drives the ITB drive roller, which rotates the ITB. The motion of the ITB causes the primary transfer rollers to rotate. The ITB cleaner cleans the ITB surface.
Primary-transfer-roller engagement and disengagement Depending on the requirements of the print job, the primary-transfer rollers engage with the ITB so it can receive toner from the photosensitive drums.
Table 1-12 Primary-transfer-roller engagement states (continued) Roller state Product state All rollers engaged The state for a full-color print job Black roller engaged The state for a black-only print job FUSER MOTOR CONTROL Figure 1-24 Three states of primary-transfer-roller engagement and disengagement Four colors are disengaged Fuser motor Y Y M M C C Four colors are engaged K K Y Y M M C C K Only black is engaged K Y Y M M C C K K The primary-transfer-roller disengagemen
If the DC controller does not receive the expected signal from the ITB home-position sensor when the primary-transfer-roller engages or disengages, but the primary-transfer-roller disengagement motor is rotating, the DC controller determines that the primary-transfer-disengagement mechanism has failed, and notifies the formatter.
ITB cleaning The cleaning blade in the ITB cleaner scrapes the residual toner off the ITB surface. The drum motor (M5) drives the residual toner feed screw. The screw feeds the residual toner to the residual toner feed unit. The residual toner feed motor (M12) drives the residual toner feed screw. The residual toner feed screw deposits the residual toner in the toner collection box.
Calibration The product calibrates itself to maintain excellent print quality. Calibration corrects color-misregistration and color-density variation. During calibration, the product places a specific pattern of toner on the surface of the ITB. Sensors at the end of the ITB read the toner pattern to determine if adjustments are necessary. Figure 1-26 Toner patterns for calibration Color misregistration control Internal variations in the laser/scanners can cause the toner images to become misaligned.
If data from the color-misregistration and image-density sensors is outside a specified range when the product is turned on or when it is beginning the calibration sequence, the DC controller determines that these sensors have failed, and it notifies the formatter. Image stabilization control Environmental changes or deterioration of the photosensitive drums and toner can cause variations in the image density. The image-stabilization control reduces these fluctuations.
Pickup, feed, and delivery system The pickup, feed, and delivery system uses a series of rollers to move the paper through the product.

Figure 1-30 Three main units of the pickup, feed, and delivery system Fuser/delivery block Duplex block Y M C K ENWW Pickup, feed, and delivery system 41
Pickup-and-feed unit The pickup-and-feed unit picks an individual sheet of paper from the multipurpose tray or the cassettes, carries it through the secondary-transfer unit, and feeds it into the fuser.
Cassette pickup The sequence of steps for the cassette-tray pickup operation is the following: 1. When the product starts or the tray closes, the lifting mechanism lifts the paper stack so it is ready. 2. After receiving a print command from the formatter, the DC controller rotates the pickup motor, which causes the cassette pickup roller, cassette feed roller, and cassette separation roller to rotate. 3. The DC controller drives the cassette pickup solenoid, which rotates the cassette pickup cam.
Cassette presence detection The cassette presence sensor is in the lifter drive unit. The sensor detects the cassette-presence sensor flag and determines whether the cassette is installed correctly.
Cassette lift operation The DC controller rotates the lifter motor (M7) and moves the lifter rack until the Tray 2 cassette lifter sensor (SR9) detects it. The lifter lifts, and the lifting plate moves up to the position where the media can be picked up. The lift operation is performed by monitoring the cassette media-stack-surface sensor when the printer is turned on, when the cassette is installed, or as needed during a print operation.
Cassette paper presence detection The cassette media-presence sensor detects whether paper is in the cassette.
Cassette media width detection The paper width 1 sensor (SR10) detects the size of the paper loaded in the cassette. The DC controller determines the paper size using the paper-width sensor. The paper-width sensor flag moves relative to the cassette-side paper guide. The pickup pressure is adjusted according to the paper size to prevent a pickup failure.
Multifeed prevention In the cassette, a separation roller prevents multiple sheets of paper from entering the paper path. The cassette pickup roller drives the separation roller through a sheet of paper. The low friction force between the sheets weakens the driving force from the cassette pickup roller. Because some braking force is applied to the cassette separation roller, the weak rotational force of the pickup roller is not enough to rotate the separation roller.
Multipurpose tray pickup The multipurpose tray paper-presence sensor detects whether paper is in the tray. If no paper is present, the DC controller notifies the formatter. Printing does not occur until paper is in the tray. The sequence of steps for the multipurpose tray pickup operation as follows: 1. After receiving a print command from the formatter, the DC controller reverses the pickup motor, which causes the multipurpose tray separation roller to rotate. 2.
Paper feed After the pickup operation, the paper feeds through the product and into the fuser. 1. The paper passes through the feed rollers. The registration shutter aligns the paper correctly to prevent skewed printing. 2. The DC controller detects the leading edge of paper by the Registration sensor (SR8) and controls the rotational speed of the pickup motor to align with the leading edge of image on the ITB. 3.
Skew-feed prevention The product can straighten the paper without slowing the feed operation. 1. As the paper enters the paper path, the leading edge strikes the registration shutter, which straightens the paper. The paper does not pass through the shutter . 2. The feed rollers keep pushing the paper, which creates a force on the leading edge against the registration shutter. 3. When the force is great enough, the registration shutter opens and the paper passes through.
OHT detection The OHT sensor detects overhead transparencies. The OHT sensor is a transmission sensor that uses an LED. The DC controller determines a media mismatch and notifies the formatter when the media type differs from the media type detected by the OHT sensor. The DC controller turns the LED in the OHT sensor on and off during the wait or initial rotation period. If the intensity of the light does not match the specified value, the DC controller determines that the OHT sensor has failed.
Loop control The loop control monitors the tension of the paper between the second-transfer roller and the fuser. ● If the fuser rollers rotate more slowly than the secondary transfer rollers, the paper warp increases and an image defect or paper crease occurs. ● If the fuser rollers rotate faster than the secondary transfer rollers, the paper warp decreases and the toner image fails to transfer to the paper correctly, causing color misregistration.
Pressure-roller pressurization control To prevent excessive wear on the pressure roller and help with jam-clearing procedures, the pressure roller pressurizes only during printing and standby. The DC controller reverses the fuser motor. The fuser motor rotates the fuser pressure-release cam.
Duplexing unit (duplex models) For supported models, the duplexing unit reverses the paper and feeds it through the paper path to print the second side. The duplexing unit consists of the following components: ● Duplexing-reverse unit: Installed on top of the product ● Duplexing-feed unit: Along the right side The DC controller controls the operational sequence of the duplex block.
Duplexing reverse and feed control The duplexing reverse procedure pulls the paper into the duplexing unit after it exits the fuser. The duplexing feed procedure moves the paper through the duplexer so it can enter the product paper path to print the second side of the page. 1. After the first side has printed, the duplexing flapper solenoid opens, which creates a paper path into the duplexing-reverse unit. 2.
Jam detection The product uses the following sensors to detect the paper as it moves through the paper path and to report to the DC controller if the paper has jammed. ● Fuser output sensor (SR5) ● Registration sensor (SR8) ● Fuser loop 1 (SR14) ● Fuser loop 2 (SR15) ● Duplexer refeed (SR22) Figure 1-45 Jam detection sensors Y M C K The product determines that a jam has occurred if one of these sensors detects paper at an inappropriate time.
Table 1-17 Jams that the product detects (continued) Jam Description Fuser delivery delay jam The fuser delivery paper-feed sensor does not detect the leading edge of the paper within a specified period after the TOP sensor detects the leading edge. Fuser delivery stationary jam The fuser delivery paper-feed sensor does not detect the trailing edge of the paper within a specified period after it detects the leading edge.
Optional paper feeder The 1x500-sheet paper feeder is optionally installed at bottom of the printer. The paper feeder picks up the print media and feeds it to the printer. NOTE: These optional trays are not identical to the main cassette (Tray 2). Figure 1-46 Optional paper feeder Y M C K The paper-deck drivers contain a microcomputer and control the paper feeder. The paper-deck drivers receive commands from the DC controller.
Figure 1-47 Signals for the paper feeder The input trays contain several motors, solenoids, sensors, and switches, as described in the following table.
Paper-feeder pickup and feed operation The paper feeder picks up one sheet from the paper-feeder cassette and feeds it to the product.
Paper size detection and cassette presence detection The paper-feeder cassette media-size switch (SW1) detects the size of paper loaded in the paper-feeder cassette. The paper-feeder driver determines the media size by monitoring the combination of the switches.
Table 1-19 Paper size detection (continued) Paper size Paper-feeder cassette media-size switch settings Top switch Center switch Bottom switch A5 On Off Off B5 Off On On Executive On Off On Letter Off On Off A4 Off Off On Legal On On Off No cassette Off Off Off The paper-feeder cassette media size switch (SW1) detects whether the paper-feeder cassette is installed correctly. The paper-feeder driver determines if a cassette is absent when all three switches are turned off.
Paper feeder cassette lift operation The cassette lift operation keeps the stack surface of paper at a specified height to maintain stable media feeding. The paper-feeder driver controls the paper-feeder lifter motor (M2) and monitors the paper-feeder media stack surface sensors (SR1, SR2) to adjust the stack height when the printer is turned on, when the printer recovers from sleep mode, when the paper-feeder cassette is installed or as needed during a print operation.
The paper-feeder driver notifies the formatter if either of the paper-feeder media-stack surface sensors fails to detect the stack surface within a specified period from when a lift-up operation starts.
Paper feeder presence detection The Tray 3 paper present (SR3) detects whether the paper is present in the paper-feeder cassette.
Paper-feeder multiple feed prevention The paper-feeder uses a separation roller to prevent multiple sheets of paper from entering the printer. The separation roller prevents multiple feeds of paper by allowing the paper-feeder separation roller to rotate in the same direction as the paper-feeder feed roller 1. The paper-feeder separation roller is equipped with the torque limiter.
Paper feeder jam detection The paper feeder uses the Tray 3 feed (SR4) to detect the presence of paper and to check whether paper has jammed. Figure 1-52 Jam detection Y M C K The paper-feeder driver identifies a jam if the sensor detects paper at a specified timing stored in the paper-feeder driver. The paper-feeder driver stops printing and notifies the formatter through the DC controller of the jam.
