Chapter 10 — Label Taken Sensor

10.1 Description

Label taken sensor
114
The label taken sensor (LTS) is an optional device, which enables the
printer's fi rmware to detect if the latest printed label, ticket, tag etc. has
not been removed and hold the printing on the next label until the present
label has been taken away from the outfeed area.
The label taken sensor is usually factory-fi tted, but it is also available as a
kit for upgrading of existing printers by an authorized service technician. It
cannot be fi tted in combination with a paper cutter.
The label taken sensor consists of a photoelectric sensor with a bracket and
a connection cable. The sensor is fi tted inside the front door, see illustra-
tion below.
The photoelectric sensor emits a narrow beam of light, which will be
refl ected back to the sensor by any label, ticket, tag, piece of strip, or liner,
that has not been removed from the outfeed area.
The LTS is connected to J53 on the CPU board. The sensitivity is adjusted
in the Setup Mode, see Chapter 10.4.
The point of detection of the LTS is situated 10 mm (0.39 inches) outside
the inner edge of the media path and 22 mm (0.87 inches) in front of the
dot line on the printhead.
