4. Turn the label gap sensor knob clockwise to secure it in the new position.
5. Try printing a label to see if the printer is detecting the start of the label
(top of form).
6. If the printer is still not detecting the top of form, slide the label gap sensor a little
further toward the outer edge of the lower media guide.
7. Replace the media cover.
Adjusting the Label Mark Sensor
The label mark sensor detects the black mark on the back of continuous media stock.
The printer uses the output to determine the start of print. The label mark sensor is
behind the platen roller and near the inboard edge of the printer. You can position the
label mark sensor no more than 6.35 cm (2.5 in) from the inboard edge of the printer.
To adjust the label mark sensor
1. Remove the media cover and locate the label mark sensor.
2. Use your index finger to slide the label mark sensor to the correct position for the
media. You can position the label mark sensor anywhere from the inboard edge of
the printer to the center of the paper path.
