Lexmark sensor (TPS)

Precision paper handling starts with accurate detection. The Lexmark 41X0383 optical paper sensor is engineered to provide reliable paper presence and jam detection in demanding office environments, ensuring your Lexmark MS/MX series printer maintains peak throughput without false stops. Unlike generic aftermarket sensors, this genuine Lexmark component is built to exact OEM tolerances, delivering consistent reflective sensing and a response time under 10 milliseconds.

Highlights

• Reflective optical sensing for dependable paper presence and jam detection
• Fast response time under 10 ms minimizes downtime and misfeeds
• Direct replacement for Lexmark part number 40X8023
• Compatible with Lexmark MS310, MS410, MS510, MS610, MX310, MX410, MX510, MX610 and related models
• Integrated 3-pin cable with connector for straightforward installation
• Operates on 5V DC, typical for Lexmark printer logic circuits
• Durable high-grade plastic housing and PCB withstands continuous use
• Snap-in or screw-in mounting depending on printer model

In daily use

When paper feeds through the printer, this sensor monitors the media path in real time. It detects the leading and trailing edges of each sheet, allowing the printer to synchronize pick rollers, fuser timing, and output stacking. If a sheet stalls or crumples, the sensor immediately signals the controller to halt and alert the user, preventing damage to internal components. Its black housing blends seamlessly into the printer chassis, and the pre-attached cable eliminates soldering or crimping. Installation is recommended to be performed by a qualified technician, as the sensor resides inside the paper path assembly.
