Moveable "see-through" for die-cut labels and
reflective for tags with black striping.
The T4204 printer uses a movable sensor to
detect index holes/notches or the black stripe in
tag stock. The transmissive sensor position is
indicated by the sensor crystal at the front of the
label guide that is visible with the printhead
open. The Reflective sensor position is located
under the R2, far right side resistor, also visible
with the printhead open. The sensor can be
moved by squeezing the two locking tabs,
located under the label guide, and sliding the
sensor assembly in or out. For proper sensing,
ensure that the sensor is aligned with the center
portion of the index hole/notch or black stripe.
Detects when a printed label is at the printer
exit throat. Used for peel-off and tear-off media
handling modes.
Peels and presents label to the operator, one at
a time.
