Chapter 26 Troubleshooting
26.7 LTS Troubles
• 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 Fingerprint program.
• Is the cable connected to P-606 on the CPU board and undam-
aged?
• Make sure that the active parts of the sensor are not obstructed
by dust or foreign objects.
• The sensitivity of the sensor’s receiver and the light intensity of
the sensor's emitter are adjustable, see Chapter 11.3.
• If still no reaction, the sensor is probably defective.
• Refer to Chapter 26.10 for problems with the built-in LTS in the
LinerLess Cutter.
• Has the clock/calendar been set?
• If TIME$ and DATE$ instructions give strange results, or time
is not updated at the right pace, replace the clock circuit IC-20.
• If the malfunction appears only after the printer has been turned
off, the trouble could be failing battery backup voltage.
Note that the TIME$ and DATE$ instructions will work by means
of the internal clock even when no real-time clock circuit is fi tted.
However, in this case time and date must be ”manually” reset after
each startup, else errors will occur. Also see Intermec Fingerprint
v6.13, Reference Manual.
