This article provides information on "Troubleshooting the 3130cn / 3130cdn Dell Laser Printer Registration Sensor"
The registration sensor detects the leading edge of the paper arriving at the registration assembly. If the registration sensor is damaged, stuck, or otherwise operating incorrectly it can cause paper jams to occur.
Location of the registration assembly.
Detail of the registration sensor within the registration assembly.
The registration sensor is optical. It is triggered by an actuator arm passing through the area the sensor monitors. As the paper path through the registration assembly is different depending on whether the paper is fed from a paper tray or the Multi Purpose Feeder (MPF) the sensor has two actuators. The image below shows the normal position of the actuator arms. No paper is present and actuator A is blocking the optical sensor.
When paper is fed from the MPF, or is returned from the duplex paper path, it enters the registration assembly from the front. While paper is present actuator A is pushed back and no longer blocks the optical sensor. When the paper has passed the actuator springs back into it's normal position.
When paper is fed from tray 1 or 2 it enters the registration assembly from the rear. While paper is present actuator B is pushed back, which pushes actuator A clear of the optical sensor. When the paper has passed both actuators spring back into their normal positions.
More info can be found in the 3130cn User’s Guide.
Back to TopThe sensor is tested by manually moving the actuators and checking the value returned by the sensor. To enter the diagnostic menu, also known as "Customer Mode".
