Reflective Media Sensor

Some types of media have black marks printed on the underside of the media liner, which act as “start of label” indicators. The reflective media sensor senses these black marks. The position of this sensor is not adjustable. If you use this type of media, refer to Media Specifications on page 153 for information about black mark requirements.

Transmissive Media Sensor

The transmissive media sensor finds “start of label” indicators, such as notches or holes in the media or interlabel gaps. This sensor consists of a light source (positioned below the media) and a light sensor (positioned above the media).

To position the sensor, complete these steps:

1.Refer to Figure 18. Turn the adjustment knob on the media guide shelf assembly to move the media sensor.
