Page 31: General Information
• “Tools required for service” on page 33 The Lexmark MX71x and MX81x are network‑capable, multi‑function laser printers that print monochrome print jobs. The operator panel is touch‑sensitive and lets the user adjust the viewing angle. All information in this service manual pertains to all models unless explicitly noted.
Page 32: Selecting Paper
7463 Weight The printer trays and multipurpose feeder can automatically feed paper weights between 60–176 g/m (16–47‑lb) grain long paper. The 2100‑sheet tray can automatically feed paper weights up to 60–135 g/m (16–36‑lb) grain long paper. Paper lighter than 60 g/m (16 lb) might not be stiff enough to feed properly, and may cause jams.
Page 33: Selecting Preprinted Forms And Letterhead
Lexmark concerns itself with the responsible use of paper in general based on life cycle assessments of its products. To gain a better understanding of the impact of printers on the environment, the company commissioned a number of life cycle assessments and found that paper was identified as the primary contributor (up to 80%) of carbon emissions caused throughout the entire life of a device (from design to end-of-life).
Page 34: Storing Paper
In addition, the company encourages purchasing paper from suppliers who demonstrate their commitment to sustainable forestry practices. Lexmark does not endorse specific suppliers, although a converter’s product list for special applications is maintained. However, the following paper choice guidelines will help alleviate the environmental impact of printing: Minimize paper consumption.

Page 282 7463 Step B Print a copy of the Quick Test Page, and check the top alignment indicators printed on the test page. The difference in the print location to the top edge of the paper between the left and right alignment indicators should be 0.5mm (one dot) or less.
Page 283: Polygon Printhead Mechanical Registration Adjustment
7463 Polygon printhead mechanical registration adjustment Complete the printhead mechanical registration adjustment procedure when you remove or replace the printhead, or loosen the mounting screws. Install the new printhead with the mounting screws lightly tightened before printing the registration Quick Test Page to see if adjustment is needed.
Page 284 7463 Locate the printhead adjustment screw access hole in the front of the printhead access cover. This will require a 3mm hex wrench to adjust. A ballhead hex wrench is suggested to make it easier to find the screw head. 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.
Page 285: Adjusting Skew
7463 One full 360‑degree turn of the printhead screw will change the skew on both edges by roughly 0.5mm (one alignment indicator dot). Warning—Potential Damage: Caution should be taken to not turn the printhead adjustment mechanism more than a few turns counterclockwise, for the screw will fully back out and will become disassembled. Stop turning the screw when you stop feeling resistance, you may need to turn it clockwise to re-engage the screw into the adjustment plate.
Page 286: Adf Skew Adjustment (Back Side)
7463 For positive skew, rotate the adjusting screw (B) clockwise, as shown in the following image. For negative skew, rotate the adjusting screw counterclockwise, as shown in the previous image.

Page 746: Rear Media Guide
7463 Rear media guide The rear media tray guide assembly can be adjusted to different media sizes by moving it to the front or rear and can be locked in position. The rear guide should come into contact with the media and hold it in position. Side media guide The media tray assembly is designed so that it can adjust to the media width in the media feed direction by moving the side guide to the left or right.
Page 747: Multi-Purpose Feeder (Mpf)
7463 Multi-purpose feeder (MPF) 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 748: Sensor (Input)
7463 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 The printer has an integrated duplex that is used to provide two-sided printing. After the first side of the page is printed, the page enters the duplex path and then re-enters the primary paper path just before the input sensor.
Page 749: Printhead
7463 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 750: Fuser Components
7463 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 751: Heat Belt (Belt Fuser)
7463 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. Pressure roll The pressure roll is used to apply pressure to the media surface for fusing.
Page 752: Exit
7463 Exit 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 753: Toner Add Motor Assembly
7463 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 755: Electrical Components And Controller
7463 Electrical components and controller 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. Sensor (rear door interlock) The sensor is a safety device to cut off a 24 VDC power supply from the LVPS to the HVPS, controller board, and to the main drive motor assembly, while the printer rear door is open.
Page 756: Lvps Board Assembly
7463 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 757 7463 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 758 7463 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 759 7463 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 760: Document Scanning At Adf
7463 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.

7463 The operational overview of a document scanning at the platen: The flatbed scanner CCD assembly travels to read the document. The exposure lamp is installed on the flatbed scanner CCD assembly. As the flatbed scanner CCD assembly travels, the document on the platen glass is scanned and exposed with the exposure lamp. The flatbed scanner CCD image sensor assembly reads the image data.
Page 762: Setting A Document
7463 Setting a document When a document is set on the document tray assembly and the lead edge is pushed into the tray until it stops, the sensor (ADF media present) becomes covered and the machine recognizes that the document has been set properly, turning on the media present LED.

7463 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 771 7463 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.
