Label Stop Sensor - Intermec EasyCoder PM4i User Manual

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 from the inner edge of the media path
and 57 mm (2.24 inches) outwards, which corresponds to the center-
line of full width media. There is one part of the sensor on top of the
upper media guide and another part underneath the lower guide. Using
a straight-slot screwdriver, turn the adjustment screw until the point of
detection on the upper sensor becomes aligned with the center of the
slots or marks in the media, when you look into the print mechanism
from the front with the printhead lifted.
• Rotate the screw clockwise to move the sensor towards the center sec-
tion.
• Rotate the screw counterclockwise to move the sensor outwards, away
from the center section.
