Label-Taken Sensor
Intermec EasyCoder 601 XP – Service Manual Ed. 3
The Label-Taken Sensor (LTS) is an optional device, which
enables the printer's firmware to detect if the latest printed label,
ticket, tag etc. has been removed before printing another copy.
The label-taken sensor is usually factory-fitted, but it is also
available as a kit for upgrading of existing printers by an authorized
service technician. It cannot be fitted 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 fitted inside the front
hatch, see illustration below.
The photoelectric sensor emits a narrow beam of light, which will
be reflected back to the sensor by any label, ticket, tag, piece of strip
or backing paper, that has not been removed from the outfeed area.
A prerequisite is that the web is fed out along the inner wall of the
printer.
The LTS is connected to P51 on the CPU board. The sensitivity of
the receiver can be adjusted by means of the potentiometer WR51
and the intensity of the emitter by a strap on P55 on the CPU board.
The point of detection of the LTS is situated 10 mm (0.39") outside
the inner edge of the paper web and 22 mm (0.87") in front of the
dot line on the printhead.
Vertical detection range is adjustable from 5 mm (0.2") above the
edge of the tear-off/dispenser edge to max. 50 mm (2") below the
edge (with strap fitted on P55).
