Positioning the Media (Transmissive) Sensors
The correct po sitioning of t he media sensors is important—it can mak e the dif ference 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 po sitioned:
• 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 i t so that the printer can detect an out-of-pa per
condition.
