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:
1 directly over the hole or notch, or
2 anywhere along the width of the media if there is a gap between labels.
if you are using continuous media, position the upper media sensor over the media so that the printer can detect an out-of-paper condition.
adjusting the upper media sensor
refer to figure 6. (for clarity, not all printer parts are shown.)
1. remove the ribbon (if it is installed).
2. locate the upper media sensor. 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. secure the upper media sensor adjustment screw.
adjusting the lower media sensor
position the lower media sensor (refer to figure 7) by sliding it in its slot until it is positioned under the upper media sensor.
