Xerox 120E40421 OEM Document Set Actuator (Sensor Actuator) – VersaLink & SetDoc Series
When your Xerox VersaLink machine shows messages like “Document Set” or “Paper Out” despite there being paper in the feeder, or if it intermittently fails to detect documents in the feeder/ADF/DADF path, the issue may lie with the document sensor actuator. The Xerox 120E40421 is the exact OEM actuator (sensor actuator / document set actuator) that manages the switching/detection required for proper document feed confirmation.
This actuator is engineered to the original specifications by Xerox, guaranteeing compatibility with several VersaLink models such as B7125, B7130, B7135, as well as C-series machines C7120, C7125, C7130. It is listed in Xerox parts catalogs under REP 5.12 (document sensor actuator) for those models.
By installing the 120E40421 actuator, you restore reliable actuation and detection in the document feeder. This reduces downtime caused by false errors, prevents unnecessary user intervention, and helps maintain quality output throughput. The part is simple to install (for service technicians or skilled users) and involves placing the actuator where the document sensor assembly resides so that it can physically engage or detect document presence correctly.
Because this is a genuine Xerox Component, performance is consistent with factory tolerances; its electrical and mechanical parts are designed to handle the duty cycle typical for medium-to-high volume office environments. Using this OEM actuator also helps maintain the device’s service warranty/parts assurance.
- Genuine Xerox part – ensures proper fit and long-term reliability.
- Restores document detection function – helps eliminate “Paper Out / Document Set” errors.
- Compatible with multiple VersaLink models – B7125, B7130, B7135, C7120, C7125, C7130.
- Easy to install – plug-and-play actuator that integrates with the existing document sensing mechanism.
- Affordable maintenance part – replacing a failing actuator is less expensive than major repairs or replacing larger assemblies.
