• “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.
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.
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).
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.
7463 Data security notice This printer contains various types of memory that are capable of storing device and network settings, information from embedded solutions, and user data: • Volatile memory—This device utilizes standard Random Access Memory (RAM) to temporarily buffer user data during simple print and copy jobs.
7463 • Make sure the paper is the recommended paper for this printer. • Make a trial print with paper from a newly opened package, and check the result.

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 • “Sensor (duplex path)” on page 772 The printer has an integrated duplex that is used to provide two-sided printing.
7463 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.
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.
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.
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.
7463 Sensor (fuser exit) The sensor (fuser exit) detects the arrival and departure of media as it passes through the fuser. Exit • “Sensor (standard bin full)” on page 777 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.
7463 Main drive motor assembly The main drive motor is a DC motor that drives the imaging unit, aligner, and MFP. Fuser drive motor assembly The fuser drive motor is a DC motor that drives the fuser. Toner add motor assembly The toner add motor is a DC motor that drives the toner cartridge in order to provide new toner.
7463 Electrical components and controller 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.
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 782
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 783
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 784
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.
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 787
7463 Described below is the overview of the steps before document scanning and that of simplex and duplex document scanning modes. 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 document sheet is fed at the feed speed corresponding to the selected magnification, and the image on it is scanned with the exposure lamp at the scan position. As the image is scanned on both sides, the document sheet is fed and ejected by the ADF feed-out roll assembly and ADF exit roll assembly that are driven by the ADF transport motor.

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 796
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.
