The
/$>P
command is used to change the sensitivity of the sensors for label gap, end pa-
per and end ribbon. This parameter is indeed used by the printer it is disabled the autocali-
bration. In the contrary case the printing treadle of time in time the more suitable value.
The command must be followed by 5 parameters in the following order:
aaa
Sensitivity of transparency sensor (/K1), 3 digits, values from 000 to 255
bbb
Not used in ST3xx series (always set to 255). Sensitivity of lateral transparency
sensor in ST4xx, ST5xx series, 3 digits, values from 000 to 255
ccc
Always refers to the same sensor in the ST3xx series but can be used to memorise
a different level to function with black mark labels.
In the ST4xx, ST5xx series, relates to the level for the specific black mark reflec-
tive sensor 3 digits, values from 000 to 255
ppp
End paper sensor. 3 digits, values from 000 a 255 (255 deactivates the sensor)
rrr
End ribbon sensor. 3 digits, values from 000 a 255 (255 deactivates the sensor)
The actual significance of these values depends on the specific parameter.
For the label transparency sensors, if the value read is higher than the level memorised in
/$>P….., a gap between one label and another is considered.
The label reflective sensors, consider a gap between the black mark when the value read is
lower than the limit.
Paper and ribbons are considered present when the values read by the respective sensors
are lower than the relative limits.
The ST3xx series only have one sensor whereas the ST4xx, ST5xx series have 3 distinct
sensors:
Lateral transparency sensor- reads from one side of the label K2…..
Central transparency sensor – reads in a more central position of the label K1….
Reflective sensor – reads in a lateral position K3…..
Sensitivity parameters are factory set during the initial quality control and their values can
vary between one printer and another because of the tolerance of the sensors. If the paper
or ribbon is significantly different to that used in the factory, one or more of these pa-
rameters may need adjusting.
Series ST3xx and ST4xx, ST5xx printers with a firmware release of 2.0 onwards have an
auto calibration function. In this case the values for the sensors are calculated automati-
cally for every print session. The values memorised in the parameter /$>P are therefore
not used.
Pre-printed labels with particular shapes or colours can generate misleading values for the
auto calibration function or in the calibration procedure and the values should be calcu-
lated manually. This procedure is possible by connecting the ST3xx or ST4xx, ST5xx to a
PC which has a terminal emulation programme. LEPTONS supplies its own TERM.EXE
