Page 274: Polygon Printhead Mechanical Registration Adjustment
4063 Step C Print a copy of the Quick Test Page, and check the top and bottom alignment indicators printed on the test page. The goal is to make the skew at the top and bottom of the page parallel. Depending on the skew, turn the screw either clockwise or counterclockwise using a 3mm hex wrench, and print a copy of the Quick Test Page to check the diamonds on the top and bottom margin.
Page 275 4063 To perform the printhead mechanical registration adjustment: Print a Quick Test Page. See “Adjustments” on page 271. If the skew between the bottom left and bottom right alignment indicators is greater than 0.5mm (1 dot), then proceed with adjustment. Otherwise, no polygon printhead adjustment is needed.
Page 276 4063 Check the Quick Test Page for any sign of misalignment by checking the diamonds at the bottom left and bottom right of the test page for equal distance from the bottom of the page. If necessary, rotate the printhead adjusting screw with a 3mm hex wrench either clockwise (to rotate the image clockwise) or counterclockwise (to rotate the image counterclockwise), and run another Quick Test Page.

Page 604: Media Tray
4063 Media tray • “Media feeder” on page 604 • “Sensor (media size)” on page 604 • “Sensor (pick roller position)” on page 604 Media feeder Media feeder Pick roller assembly The pick roller assembly which is part of the media feeder, is a mechanical unit supplying media from the media tray to the paper path.
Page 605: Mpf Pick Roller
4063 The MPF is a mechanical unit supplying media to the printer. The driving force from the main drive motor drive motor is transmitted to the MPF pick roller to feed media. MPF pick roller The MPF pick roller feeds the media placed in the MPF media tray into the printer. MPF pick solenoid The MPF pick solenoid transmits the driving force from the main drive motor assembly to the MPF pick roller.
Page 606: Sensor (Input)
4063 Sensor (input) The sensor (input) is located just before the print cartridge and can detect whether media exists in the input path. The sensor is used to detect jams and to set functional timing. Duplex • “Sensor (duplex path)” on page 606 The printer has an integrated duplex that is used to provide two-sided printing.
Page 607: Transfer Roller
4063 Transfer roller The transfer roller applies charge to the rear surface of the media when the media passes between the transfer roller and photo conductor (drum). The toner image is transferred from the photo conductor (drum) surface to the media surface.
Page 608: Printhead
4063 Printhead The printhead scans the photoconductor drum surface with a laser beam. It consists of four components: laser diode (LD) card assembly, printhead motor, polygon mirror, and the start of scan card assembly. LD card assembly—The LD card assembly generates the laser beam. The beam is turned on or off according to a print data signal coming from the controller board.
Page 609: Fuser Components
4063 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 610: Heat Belt (Belt Fuser)
4063 Heat belt (belt fuser) The heat belt is a thin metal belt with a coated surface. This belt is heated by a ceramic heater bar. The heat is applied to the media passing between the heat belt and pressure roll, fusing the toner on the media. Heat belt (hot roll fuser) The heat roll is a hollow metal tube with a coated surface.
Page 611: Heater Lamp (Hot Roll Fuser)
4063 Heater lamp (hot roll fuser) The heater lamp is a quartz glass tube containing a halogen heater coil. A terminal is mounted to the end of the heater rod using a harness. Thermistor The thermistor monitors the surface temperature of the media-feed portion of the heat belt or heat roll to provide feedback to the controller board.
Page 612: Sensor (Standard Bin Full)
4063 The standard media exit ejects printed media from the printer to the standard bin . Sensor (standard bin full) The sensor (standard bin full), along with the standard bin full flag, detects whether the standard bin is full and stops the printing process.
Page 613: Toner Add Motor Assembly
4063 Toner add motor assembly The toner add motor is a DC motor that drives the toner cartridge in order to provide new toner. Redrive motor assembly The redrive motor assembly is a DC motor that drives the redrive assembly that transports the media into the duplex path entrance, standard bin, or output option.

Page 615: Sensor (Control Panel Door Interlock)
4063 Main cooling fan LVPS card assembly Controller board Duplex cooling Print cartridge cooling fan HVPS card assembly Sensor (control panel door interlock) The sensor is a safety device to cut off a 24 VDC power supply from the LVPS to the high volt power supply (HVPS), controller board, and to the main drive motor assembly, while the control panel door is open.
Page 616: Lvps Board Assembly
4063 LVPS board assembly The LVPS board assembly generates 6.5V and 25V DC voltages. The LVPS can be switched to work with 100V, 110, and 220V machines. HVPS board assembly The HVPS board assembly generates and provides DC voltages to the developer roll, the transfer roller, and the charge roller (located in the imaging unit).
Page 617 4063 Exposure The Printhead generates a beam of laser light. Image data received from the controller board assembly modulates this beam, turning it on and off according to image information that is received from the host computer and software. Through the use of a series of rotating and stationary mirrors within the Printhead, the beam scans the negative charged drum surface.
Page 618 4063 Development The toner contained within the PC cartridge has an electrical property that causes it to adhere to the development roller. The metering blade spreads the toner into a very thin layer on the development roller. Friction between the development roller and the CM blade development roller generates a small electrical charge that is transferred to the toner.
Page 619 4063 Transfer As the paper travels between the transfer roller and the photoconductor (drum), the Transfer roller applies a positive 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 620: Supported Paper Sizes, Types, And Weights
4063 Auto density sensing 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 625: High Capacity Output Expander Theory
4063 When the output expander is installed on top of the printer, the diverter plunger changes the position of the diverter below it. Since the diverter position of the printer below is opened, the printed paper will be re-routed. Instead of exiting the standard output bin, the media enters the output expander.
Page 626: Mailbox Theory
4063 When the HCOE is installed on top of the printer, the diverter plunger changes the position of the diverter below it. Since the diverter position of the printer below is opened, the printed paper will be re-routed. Instead of exiting the standard output bin, the media enters the HCOE.
Page 627: Staple Finisher Theory
4063 The main motor drives the transport rollers which move the media along the paper path. The sensor (pass through) detects if the media has entered the mailbox. Four diverters control which way the media will go. If a diverter is opened, then media will pass through it and go to the next diverter above it.
Page 628 4063 Stapling process Exit rollers move the media to the tamper where it will be prepared for stapling. Multiple pages can be stacked on the tamper before the document is stapled. The paddle drive motor rotates the paddle rollers for aligning the trailing edge of the pages.
