Papieraanwezigheidssensor-actuator Lexmark 40X8800 — sensoreenheid voor papierdetectie

Paper Present Sensor Actuator Lexmark 40X8800 — sensor assembly for paper detection is a replacement part designed to restore paper-detection functionality in compatible Lexmark printers. The unit senses the presence or absence of paper at a designated feed point and sends a signal to the printer control system to allow or pause feeding. It is intended for service and maintenance use to correct misreads that can cause misfeeds, false paper-out errors, or interrupted print jobs.

Advantages

The sensor assembly provides accurate and repeatable paper presence detection, helping reduce false paper-out conditions and feed errors. Its plug-and-play form factor aligns with original equipment mounting points and electrical connectors to simplify installation. Constructed for reliable operation under typical office printing cycles, the component supports consistent sensor response and helps maintain overall printer uptime.

Suitable for

• Replacing a failed or intermittent paper present sensor in compatible Lexmark printers
• Printer maintenance and service to resolve misfeed and false paper-out errors
• Repair shops and in-house IT teams performing parts-level replacement

Key specifications

• Function: paper presence detection (sensor actuator)
• Compatibility: designed for compatible Lexmark printer models requiring the same sensor form factor and connector
• Mounting: replacement assembly matching original sensor mounting points
• Electrical: low-voltage signal output compatible with printer control logic
• Durability: designed for repeated actuation typical in office printing environments

How to use

Power off the printer and disconnect it from mains before beginning any service. Access the sensor location according to the printer service manual or manufacturer guidance, remove the defective assembly and disconnect its connector, then fit the replacement sensor actuator into the correct mounting position and reconnect the cable. Reassemble any covers, restore power, and perform a paper feed test or printer self-test to verify correct detection and feeding behavior.

Recommendations

Use the replacement sensor only in compatible printer models and follow manufacturer service instructions. Handle the assembly with care to avoid contaminating the sensing surface or damaging the connector. If paper-detection issues persist after replacement, inspect adjacent feed rollers, guides, and the paper path for wear, dust, or misalignment before replacing other components.
