Sensor Positioning The printer has a moveable sensor to detect
inter label gaps, black lines or marks, and index
holes/notches on the media. For optimal opera
-
tion, the sensor should be adjusted to center on
the label, black mark or index hole (or notch) of
the media in use.
Typically, media does not require a media sen
-
sor position adjustment if the sensor is pulled to
the outside adjustment position. The sensor po
-
sition can be moved by squeezing the two lock
-
ing fins, located under the media sensor and
guide assembly, and sliding the sensor in or out.
Top Of Form
Sensing
To accommodate different media and media
dimensions, your printer is equipped with sen-
sors capable of detecting the top of form for la-
bels or tags. Two methods are used by the
printer for top of form sensing: gap sensing and
black mark sensing. The sensors are combined
into a single sensor assembly in the media sen-
sor and guide assembly.
Gap Sensing The gap sensing feature depends on the ability
of the transmissive (gap) sensor to “see
through” the label liner between labels. Label
and label backing opacity vary due to manufac
-
turing differences in label stock. The sensor may
have difficulty distinguishing the difference be
-
tween labels and the liner and may require the
user to AutoSense the media. Set the gap sen
-
sor’s sensitivity with the AutoSense feature.
Black Mark
Sensing
The black mark uses a reflective (black mark)
sensor to detect a black line (mark) on the me
-
dia backing. The black mark sensor is used with
special labels that have a black mark printed on
the back of the label liner or tag between each
label or tag.
