The correct positioning of the media sensor is important — it can make the difference
between a perfect label and a call to Technical Support!
There are two media sensors in this printer: “reflective” and “transmissive.”

The reflective sensor detects the “start-of-label indicator” (the notch, hole, black
mark, or gap between die-cut labels).
The reflective sensor must be positioned:
directly under the notch, hole, or black mark, or
anywhere along the width of the media if there is a gap between labels
The glow of the red light through the media helps you to accurately position the
reflective sensor.
NOTE: If you are using continuous media, position the reflective sensor
anywhere under the media so that the printer can detect an out-of-paper
condition.
NOTE: The reflective sensor is compatible with most types of media.
However, if you encounter difficulties with calibration, use the transmissive
sensor. For details, see “Transmissive Sensor” on page 10.
