Page 524: Mpf
4062 When the pick rolls pick up media, the remaining media decreases, and the media out actuator will lower and interact with the sensor (media low) and sensor (media empty) to determine the amount of media remaining. The pick arm assembly (autocompensator) is a paper pick device that generates its own normal force. This force generation is inherent in the fundamental design of the pick arm.
Page 525 4062 Part MPF pick solenoid Sensor (MPF media empty) MPF pick roll assembly MPF feed roll The MPF pick roll feeds the media set on the MPF into the printer. MPF pick solenoid The MPF pick solenoid transmits the driving force from the main drive motor assembly to the MPF pick roll. Sensor (MPF media empty) The sensor (MPF media out) detects whether media is present on the MPF.
Page 526: Registration
4062 Registration Part Aligner assembly Sensor (input) Sensor (input) The sensor (input) is located just before the print cartridge and can detect whether media exists in the input path. Aligner assembly The aligner assembly is used to feed the media through the input path and to ensure that media is fed through the machine in a perfectly straight manner and not in a skewed manner.
Page 527: Transfer
4062 Transfer Part Transfer roll Transfer roll assembly The transfer roll assembly applies charge to the rear surface of the media when the media passes between the transfer roll assembly and photo conductor (drum). Thus, the toner image is transferred from the photo conductor (drum) surface to the media surface.
Page 528 4062 Part Polygon printhead LD card assembly — This generates the laser beam. The beam is turned on or off according to a print data signal coming from the system card. Printhead motor/polygon mirror — The polygon mirror is mounted to the shaft of the printhead motor, and is rotated at a high speed by the printhead motor.
Page 529: Oscillating Printhead Assembly
4062 When a laser beam is scanned across the photoconductor (drum) surface from one end to the other while turning on and off the beam, one line of latent image is created. If the scanning by the laser beam is repeated while rotating the drum, a two-dimensional image is created.

Page 532 4062 Part Fuser unit assembly Sensor (fuser output) Sensor (narrow media) Fuser solenoid Pressure roll Fuser lamp Heat roll The heat roll is a hollow metal tube with a coated surface. This tube is heated by the inner heater lamp. The heat is applied to the media passing between the heat roll and pressure roll, fusing the toner on the media.
Page 533: Fuser Unit Assembly (Types 1 And 2)
4062 Thermistor The thermistor monitors the surface temperature of the media-feed portion of the heat roll to control on/off of the main heater lamp and sub heater lamp. Sensor (fuser output) The sensor (fuser output) detects the arrival of media at the detection point in the exit area of the fuser, and also detects the ejection of media from this point.

4062 Part Sensor (standard bin exit) Sensor (standard bin full) The sensor (standard bin full) detects whether the standard bin is full by moving the actuator up and down. Drive Main drive motor assembly The main drive motor is a DC motor that drives the print cartridge, aligner, MFP, and fuser. Redrive motor assembly The redrive motor assembly is a DC motor that drives the redrive assembly that transports the media into the standard bin or output option.

4062 Electrical components and controller Part LVPS card assembly Duplex cooling fan Print cartridge cooling fan HVPS card assembly System card assembly Main cooling fan Switch (printer front door interlock) The switch is a safety switch to cut off a 24 VDC power supply from the LVPS card assembly to the high volt power supply (HVPS) card assembly, printer system card assembly and to the main drive motor assembly, while the printer front door assembly is open.
Page 537: Printhead Control
4062 LVPS card assembly The LVPS card assembly generates low voltages 5V for logic circuits, 5V for laser diodes, and 24V for cooling fans. The LVPS is switchable and can be switched to work with 100V, 110V, and 220V machines. HVPS card assembly The HVPS card assembly generates AC power and feeds it to the developer roll, the transfer roll assembly, and the charge roll assembly.
Page 538: Xerographic And Print Cartridge Components
4062 The fuser temperature control starts when the fuser ready in the system card assembly is turned on after a preset time period has passed from power on. If a failure occurs, the heater lamps are turned off, the fuser ready is turned off, and then the fuser temperature control is stopped.
Page 539 4062 Charge The charge roll places a uniform negative electrostatic charge on the surface of the drum. The drum surface is made of a photoconductive material that holds an electrical charge as long as the drum remains in darkness. Light striking the drum discharges the surface charge. HVPS Charge roll (-VDC)
Page 540 4062 This discharge/no discharge process creates an invisible, electrostatic image on the surface of the drum. This image is called a latent image. Modulated Laser Beam Printhead DRUM Drum Surface Drum Surface Image Voltage Laser Beam Laser Beam Discharge Level Invisible Latent Image Development The toner contained within the PC cartridge has an electrical property that causes it to adhere to the...
Page 541 4062 The toner adhering to the development roll is always in contact with the drum surface. When a less negative point on the drum (a discharged area) comes in contact with the more negative charged toner on the magnet roll, toner transfers from the magnet roll to that point on the drum. There is now a visible toner image on the drum surface.
Page 542 4062 Transfer As the paper travels between the transfer roll and the photoconductor (drum), the transfer roll applies a charge to the back of the printing paper. This positive charge transfers the negative charged toner image from the photoconductor (drum) to the top surface of the paper. The toner image is now on the paper and the paper is now stuck to the photoconductor (drum) due to the relative electrical differences between the negative electrical charge of the inner conductive layer of the drum and the positive electrical charge of the paper.
Page 543 4062 Auto density sensing The cleaning blade removes any toner that remains on the drum after the transfer process. The toner that the cleaning blade removes is collected inside the sealed PC cartridge. Part Sensor shield assembly Sensor (toner density) The image density sensor assembly uses a reﬂection type sensor that detects a pre-placed toner patch and image on the photoconductor (drum) and outputs pulses when the central line of the patch image aligns with the central line of the detector.

Page 546 4062 Media size sensing The media size set for the media tray assembly is set by positioning the right media guide, unlocking the slider lock, and sliding the rear paper guide.

Page 548 4062 Switch (media size) This switch (media size) sets the size of media supplied from each media tray assembly. A signal indicating the media size is transmitted as a voltage to the printer system card assembly.

Page 593 Print defects guide Page 1 of 1 Print defects guide Match a set of repeating defects on a print job to the marks on one of the vertical lines. The line that best matches the defects on the print job indicates which particular part may be causing the defect. For example, the distance between these two marks represents a repeating defect that occurs every 28.3 mm (1.11 in.), which means the charge rollers may need to be replaced.
