2.5.6.2 Detection Mode - Blackline (1)
This detection mode is used when a black line on the underside of the media is used to
register the labels. The Lower Sensor detector “senses” the amount of light reflected off of
the label from the Lower Sensor emitter. While registration is determined by the Lower
Sensor only in this mode, the upper gap sensor is used for out-of-stock or stock out
conditions.

2.5.6.3 Detection Mode - Die-cut (2) and Blow-hole (3)
Die-cut sensing refers to die-cut label registration where the difference in the transparency
of [label] and [label + backing] is detected (gap between labels is registration point).
Blow-hole sensing refers to label stock with holes punched out as registration marks. In this
case, the Upper and Lower Sensors must be aligned so that the hole in the stock passes
over the sensors.
Dies-cut and blow-hole use the same basic method of detection. However, because of the
difference in light intensity and stock out detection, they each require their own Detection
Mode setting (^D636).
