Hello my dear experts! I am trying to repair this ilumination sensor from a Xerox scanner system. This sensor gives information to the controller about the intensity of the scanner light (Value: 1 to OFF and 50 to 150 to ON). This sensor have only 2 wires and with the voltimeter it gives roughly 14v. I don´t know how it "sends" the value to the controller. My main question is if anyone can tell me what the indicated component is. Is seems some sort of photoresistor? I send the photo with the component protection and without. Thank you in advance from Portugal! |
