1 Theory of operation ● Basic operation ● Engine control system ● Laser/scanner system ● Image formation system ● Pickup, feed, and delivery system ● Jam detection ● Optional paper feede.
Basic operation The product routes all high-level processes thro ugh the formatter, which stores font information, processes the print image, and communicates with the host computer.
Sequence of operation The DC controller PCA controls the operating se quence, as described in the following table. NOTE: The terms fusing and fixing are synonymous.
Engine control system The engine-control system receives commands from the formatter and interacts with the other main systems to coordinate all product functions.
DC controller The DC controller controls the oper ational sequence of the printer. Figure 1-3 DC controller block diagram Fuser Laser/scanner ENWW Engine control system 5.
Solenoids Table 1-2 Solenoids Component abbreviation Component name SL1 Primary transfer roller disengagement solenoid SL2 Duplex reverse solenoid (HP LaserJet Enterp rise 500 color M551dn and HP Lase.
Sensors Table 1-5 Sensors Component abbreviation Component name SR1 Drum home position sensor 1 SR2 Drum home position sensor 2 SR3 Drum home position sensor 3 SR5 Fuser output sensor SR6 Output bin f.
The product has 11 motors and three fan motors. Th e motors drive the components in the paper-feed and image-formation systems. The fan motors cool the product's inside.
Table 1-6 Motors (continued) Abbreviation Name Purpose T ype Failure detection M12 Residual toner-feed motor Drives the residual toner feed screw DC motor Yes M13 Pickup motor Drives the cassette pick.
High voltage power supply The high-voltage power supply delivers the high-vol tage biases to the following components used to transfer toner during the image-formation process: ● Primary-charging ro.
Table 1-8 High voltage power su pply circuits (continued) Circuit Descrip tion Primary-transfer-bias generation DC positive bias transfer s 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 th e AC power from the wall receptacle into the DC voltage that the product components use. The pr oduct has two low-voltage power-supplies for 110 Volt or 220 Volt input. Figure 1-5 Low voltage power-supply circuit +3.
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.
Overcurrent/overvoltage protection The low-voltage power supply stops supplying the DC voltage to the product components whenever it detects excessive current or abnorma l voltage from the power source. The low-voltage power supply has a protective circ uit against overcurrent and overvoltage to prevent failures in the power supply circuit.
Power off condition The DC controller turns off the product with th e 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.
Fuser temperature control circuit The temperatures of the two rollers in the fuser fluctu ate according to the stage of the printing process. The DC controller sends commands to the fu ser-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.
Fuser failure detection When the DC controller detects any of the following conditions, it d etermines 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 electrosta tic image on the photosensitive drums according to the VIDEO signals sent from the formatter. The pr oduct has two laser/scanners: one for yellow and magenta and the other for cyan and black.
The DC controller determines that a laser/scanner has failed when any of the following conditions occurs: ● Laser failure : The detected laser intensity does not ma tch a specified value when the product initializes. ● Beam-detect (BD) failure : The BD interval is outside a specified range during printing.
Image formation system The image-formation system creates the printed imag e 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.
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 photose nsitive drum and charges the drum with negative potential.
Step 3: Laser-beam exposure The laser beam strikes the surface of the photosensi tive drum in the areas where the image will form. The negative charge neutralizes in those ar eas, which are then ready to accept toner.
Step 5: Primary transfer The positively charged primary-transfer rollers contac t the ITB, giving the ITB a positive charge. The ITB attracts the negatively charged toner from the surf ace 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 fr om the ITB as the ITB bends. The static-charge eliminator removes excess charge from the pape r to ensure that the toner fuses correctly.
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.
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 th e photosensitive drum, developing unit, and primary charging roller.
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 ti me period or the cartridge runs out of toner.
The DC controller rotates the developing disengag ement 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, al l four of the developing rollers disengage from the photosensitive drums.
Intermediate transfer belt (ITB) unit The ITB unit accepts the toner images from the phot osensitive drums and tra nsfers the completed image to the paper.
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 stat e for a black-only pr.
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 pr imary-transfer-disengagemen t mechanism has failed, and notifies the formatter.
ITB cleaning The cleaning blade in the ITB cleaner scrapes the re sidual toner off the ITB surface. The drum motor (M5) drives the residual toner feed screw. The scre w feeds the residual toner to the residual toner feed unit. The residual toner feed motor (M12) drives the residual toner feed screw.
Calibration The product calibrates itself to maintain excellent pr int quality. Calibration corrects color-misregistration and color-density variation. During calibration, the product places a specific pa ttern 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.
If data from the color-misregistration and image-de nsity 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.
Pickup, feed, and delivery system The pickup, feed, and delivery system uses a series of rollers to move the paper through the product. Figure 1-27 Switches and sensors for the pickup , feed, and deli.

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-transf er unit, and feeds it into the fuser.
Cassette pickup The sequence of steps for the cassette-tr ay pickup operation is the following: 1. When the product starts or the tray closes, the lift ing mechanism lifts the paper stack so it is ready.
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 mo ves the lifter rack until the Tray 2 cassette lifter sensor (SR9) detects it. The lifter lifts, and the lift ing plate moves up to the position where the media can be picked up.
Cassette paper presence detection The cassette media-presence sensor detec ts whether paper is in the cassette. Figure 1-35 Paper level detection mechanism 46 Chapter 1 Theory of operation ENWW.
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 senso r. The paper-width sensor flag moves relative to the cassette-side paper guide.
Multifeed prevention In the cassette, a separation roller prevents multip le sheets of paper from entering the paper path. The cassette pickup roller drives the separa tion roller through a sheet of paper. The low friction force between the sheets weakens the driving force from the cassette pickup roller.
Multipurpose tray pickup The multipurpose tray paper-presence sensor detects wh ether paper is in the tray. If no paper is present, the DC controller notifies the formatter. Prin ting does not occur until paper is in the tray. The sequence of steps for the multipurpo se tray pickup operation as follows: 1.
Paper feed After the pickup operation, the paper feed s 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.
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 .
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 senso r.
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 se condary transfer rollers, the paper warp increases and an image defect or paper crease occurs.
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.
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.
Jam detection The product uses the following sensors to detect th e paper as it moves through the paper path and to report to the DC controller if the paper has jammed.
Table 1-17 Jams that the product detects (continued) Jam Description Fuser delivery delay jam The fuser delive ry paper-feed sensor does not detect the leading edge of the paper within a specified period after the TOP se nsor 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.
Figure 1-47 Signals for the paper feeder The input trays contain several motors, solenoids, se nsors, and switches, as described in the following table.
Paper-feeder pickup and feed operation The paper feeder picks up one sheet from the pap er-feeder cassette and feeds it to the product. Figure 1-48 Paper-feeder pickup and feed operation ENWW Optional.
Paper size detection and cassette presence detection The paper-feeder cassette media-size switch (SW1) d etects the size of paper loaded in the paper-feeder cassette. The paper-feeder driver determines the me dia size by monitoring the combination of the switches.
Table 1-19 Paper size detection (continued) Paper size Paper-feed er cassette media-si ze switch settings Top switch Center switch Bottom switch A5 On Off Off B5 Off On On Executive On Off On Letter O.
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 notifies th e formatter if either of the pape r-feeder media-stack surface sensors fails to detect the stack surface within a specifie d 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. 66 Chapter 1 Theory of operation ENWW.
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 f eed roller 1.
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 sens or detects paper at a specified timing stored in the paper-feeder driver.
