Positioning the Media (Transmissive) Sensors
The correct positioning of the media sensors is important—it can make the difference between
a perfect label and a call to Technical Support!
The web or gap sensor, also known as the “transmissive sensor,” detects the gap between
labels. The transmissive sensor actually consists of two sections: a light source (the lower
media sensor) and a light sensor (the upper media sensor). The media passes between the two.
The upper media sensor must be positioned:
• Directly over the hole or notch, or
• Anywhere along the width of the media if there is a gap between labels.
To adjust the upper and lower media sensors, complete these steps:
1. Remove the ribbon (if it is installed). Refer to page 32 for instructions.
2. Locate the upper media sensor ( Figure 30 ). The upper media sensor “eye” is directly
below the adjustment screw head.
3. Slightly loosen the upper media sensor adjustment screw (use a Phillips-head
screwdriver).
4. Using the tip of the screwdriver, slide the upper sensor along the slot to the desired
position.
5. Tighten the upper media sensor adjustment screw.

Note • If you are using continuous media, position the upper media sensor over the media
with the lower media sensor directly below it so that the printer can detect an out-of-paper
condition.
