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
