Lexmark M1140 MS315 MS410 MS415 MX410 XM1140 Galvo Laser Scanner LSU 40X8081

Lexmark Laser Scanning Unit – 40X8081

Replacement laser scanner assembly for select Lexmark M1140, MS315, MS410, MS415, MX410 and XM1140 printers.

Product Overview

The Lexmark 40X8081 Laser Scanning Unit, also called an LSU, laser scanner, laser printhead or Galvo scanner, is an internal imaging component responsible for directing the printer’s laser beam across the photoconductor drum.

During printing, the laser scanning unit converts electronic print data into a precisely controlled laser pattern. That pattern creates the latent image on the imaging drum before toner is applied and transferred to the paper. A malfunctioning LSU may prevent the printer from initializing or may cause missing, faded or distorted areas on printed pages.

Compatible Make and Brand

Part number 40X8081 is cataloged for compatible Lexmark monochrome laser printers and multifunction printers. No compatibility with Dell, IBM, Konica Minolta or other printer brands should be assumed unless the original installed component is specifically marked 40X8081.

Common Symptoms of LSU Failure

• Laser-scanner, printhead or LSU-related service errors
• The printer does not complete its startup sequence
• Blank pages despite toner and imaging-unit operation
• Faded or missing horizontal areas across printed pages
• Repeating light bands or inconsistent print density
• Distorted, compressed or improperly positioned print
• Unusual grinding, whining or high-pitched noise during initialization

Galvo-versus-Polygon Compatibility

Important Diagnostic Information

Faded output, blank pages and print-positioning problems may also be caused by the toner cartridge, imaging unit, controller board, high-voltage power supply, wiring or contaminated optical surfaces. Verify the failure before replacing the laser scanning unit.

If the scanner optics are contaminated, carefully inspect and clean the appropriate optical surfaces using service-approved procedures. Do not touch internal mirrors or lenses with bare hands, and do not use liquids or abrasive materials unless directed by the service manual.

Installation

Replacing the LSU requires disassembly of the printer and access to internal electrical and optical components. Disconnect the printer from electrical power before beginning service. Protect the imaging unit from prolonged light exposure and observe appropriate electrostatic discharge precautions. Professional installation is recommended.
