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.
