Position the Label Sensor

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
• anywhere along the width of the media if there is a gap between labels

The glow of the red light through the media may help you accurately position the 
reflective sensor.

Refer to the illustration on the next page.

Open the printhead assembly by pressing the printhead open lever.

2. Locate the reflective sensor positioning lever.

3. Move the reflective sensor positioning lever across the width of the media until the 

reflective sensor aligns with the gap or notch. The glow of the red light assists in 
the proper placement of the reflective sensor.

Note • If you are using continuous media, position the reflective sensor anywhere 
under the media to detect an out-of-paper condition. The reflective sensor is 
compatible with most types of media. If you have difficulties with calibration, use the 
transmissive sensor. See 

Caution • Ensure printhead is fully open and engaged in the up position. Failure to 
latch in the up position could result in the printhead falling on your hand during the 
procedure.
