TFC338CS Wireless Network Card for Lexmark CX431 XC2326 Printers

Internal Wi-Fi Module for Lexmark Printer Chassis

The TFC338CS wireless network card is an internal module that adds Wi-Fi connectivity to compatible Lexmark printers. It installs in the controller board option slot and carries part number 41X1873. The card is RoHS compliant and ships as a single unit.

The module fits Lexmark CX431, XC2326, C2326 and CS431 series printers. It also serves the MC3224adwe, MC3326 and MC3426 models. Lexmark excludes the MX522 and XM1246 from the compatibility list. The card replaces a failed wireless module or upgrades a wired-only chassis.

Installation requires removing the controller board cover and seating the card in the option slot. The printer detects the module on boot and exposes wireless settings in the embedded web server. A separate wireless module cable, part 41X2270, carries the antenna signal on some chassis.
