Label Stop Sensor

The label stop/black mark sensor (LSS) is a photoelectric sensor that controls the printer’s media feed by detecting gaps between labels, or slots or black marks in continuous stock, depending on the printer’s setup

in regard of media type (see Chapter 6, “Setting Up the Printer”). An obvious prerequisite is that the LSS must be aligned with the gaps, slots, or black marks. If using-irregularly shaped labels, align the LSS with the front tips of the labels.

The LSS can be moved laterally between 5 fixed positions. There is one part of the sensor on top of the upper media guide and another part underneath the lower guide. These must be adjusted individually to the same position. Using a small screwdriver, push them inwards as far as they go and then pull them out—one at the time—while counting the clicks from the snap-locks. A hole in the bottom plate facilitates adjust- ment of the lower sensor package.

The various detection points of the sensor in relation to the inner edge of the media are as follows:

One click out	3 mm	.118 inches
Two clicks out	8 mm	.315 inches
Three clicks out	12 mm	.472 inches
Four clicks out	16 mm	.639 inches
Five clicks out	20 mm	.787 inches
