Lexmark Front Door Sensor – 40X8048

Genuine Lexmark service component for select M, MS, MX and XM Series monochrome laser printers.

Product Overview

Restore proper front-door detection with the Lexmark 40X8048 Front Door Sensor. This internal sensor monitors the position of the printer’s front access door and communicates whether the door is properly closed. A damaged, worn or unresponsive sensor may prevent the printer from entering a ready state, even when the front door appears to be completely closed.

Part number 40X8048 is designed for a wide selection of Lexmark monochrome printers and multifunction devices built on the MS310, MS410, MS510, MS610, MX310, MX410, MX510 and MX610 platforms.

Compatible Make and Brand

This part is cataloged as a genuine service component for Lexmark printers. Compatibility with similarly designed Dell, IBM, Source Technologies or Konica Minolta machines should not be assumed solely because those products may share certain Lexmark-based components.

Common Symptoms of a Faulty Front Door Sensor

• The printer reports that the front door is open when it is physically closed.
• The printer remains in a “Door Open” or “Close Front Door” state.
• The printer will not initialize or enter the ready state.
• The printer operates intermittently when pressure is applied to the front door.
• The door must be opened and closed repeatedly before the printer responds.
• The sensor does not respond when its actuator is manually engaged.

Important Diagnostic Information

A front-door warning is not always caused by the sensor itself. Before ordering, inspect the front door, sensor actuator, plastic flag, mounting points, wiring and electrical connections for damage or misalignment. A broken door tab or actuator may prevent a functional sensor from being engaged.

Installation

Installation requires partial disassembly of the printer and access to internal electrical components. Disconnect the printer from electrical power before beginning service. Professional installation is recommended if you are unfamiliar with printer repair or electrical-component replacement.
