Malfunctions, cont.

Description:
The label taken sensor (LTS) is not working properly.
Possible Causes and Suggested Remedies:
• Intermec Fingerprint instruction missing.
- The LTS must either be enabled by means of an LTS& ON
statement, or the status of the LTS must be polled by means of
a PRSTAT function, in the current Intermec Fingerprint pro-
gram.
• Bad connection.
- Check that the cable is connected to P51 on the CPU board
and undamaged.
• Dirty or misaligned sensor.
- Make sure that the active parts of the sensor are not obstructed
by dust or foreign objects and that the bracket is not bent so
as to cause misalignment.
• Wrong LTS sensitivity.
- The sensitivity of the sensor's receiver and the light intensity
of the sensor's emitter are adjustable, see Chapter 10.3.
• Defective sensor.
- If still no reaction, the sensor is probably defective and should
be replaced.
