3. Using a Phillips-head screwdriver, slightly loosen the upper media sensor adjustment
screw.
4. Using the tip of the screwdriver, slide the upper sensor along the slot to the desired
position (for non-continuous media with a notch or hole in the media, the sensor must be
directly above the notch or hole).
5. Tighten the adjustment screw to secure the upper media sensor.
Note • T he upper media sensor can be positioned along the inside half of the media (the side
closest to the back of the printer) or the outside half of the media (the side farthest from the
back of the printer).
