Label Stop Sensor

132 EasyCoder PX4i Bar Code Label Printer User's Guide (Fingerprint Version)
The label stop 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. The LSS should 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 label stop/black mark sensor (LSS) can be moved laterally
within a range of 0 to 50 mm (0 to 1.96 in) from the inner edge
of the media path. There is a screw running through the outer
lower gable. Turning the screw clockwise will move the LSS
inwards and vice versa. The position of the LSS in relation to the
media is best checked by looking head on into the print unit
when the printhead is raised. Align the center point of the V-
shaped upper sensor with the center of the slots or marks to be
detected.
The linear markings on the lower guide plate can also be used for
positioning of the LSS because they are spaced with an interval of
exactly 1 cm (0.39 in). This method is especially useful for black
marks (measure the lateral position of the black marks with a
ruler before loading the media).
