Doors Front with Duplex

Lexmark 40X7635 front doors with duplex are a service replacement part for compatible CS31x printers. The part number and front-door description are confirmed in Lexmark’s parts listing.

This component is intended for the printer’s front area and is specified for the duplex configuration. It is a printer part, not a complete printer or a standalone duplex unit. The exact model fit can vary, so the confirmed reference here is the CS31x series rather than a broader list of printer models.
