Transmissive Media Sensor The transmissive media sensor finds “start of label” indicators, such as notches or holes in the media or interlabel gaps. The sensor lowers brightness in dark locations and raises brightness in light locations. Adjust the sensitivity setting to determine how much motion it will take to engage the light. Locate the brake light switch. This means that the sensor doesn’t work properly and the light basically runs out of battery after, like an hour into the evening. Step 1. If the zone is too short, raise the head, but keep it at least 1 in. Before we can properly understand light sensors and how to apply them, we need to be able to quantify light.
