10. Label Taken Sensor

10.1 Description

Intermec EasyCoder 501 XP & 601 XP – Service Manual
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 been removed before printing another copy.
The label taken sensor is usually factory-fi tted, but it is also avail-
able 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
hatch, see illustration below.
Label Taken Sensor
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 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 inches)
outside the inner edge of the media path and 22 mm (0.87 inches)
in front of the dot line on the printhead.
Vertical detection range is adjustable from 5 mm (0.2 inches)
above the edge of the tear bar to max. 50 mm (2 inches) below the
edge (with strap fi tted on P55).
