Adjusting the Label Stop Sensor
The label stop sensor (also called label gap sensor or black mark
sensor) is a photoelectric sensor that controls the media feed by
detecting gaps between labels, or slots or black marks in continuous
stock. For the sensor to work, it must be aligned with the gaps, slots,
or marks on the media. If you are using irregularly shaped labels, align
the sensor with the front tip of the labels.
Note: Be sure you make identical adjustments on both screws. If you
are unsure, tighten both screws completely by turning them
counterclockwise as far as they will go, and then start over.
