Positioning the Media Sensor

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.”

Reflective Sensor

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 will help 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. See “Transmissive Sensor” on page 12.
