Label Stop Sensor
Position
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 fi xed 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 
gives access to the lower sensor part.
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
