SENSOR 
READINGS 
 
Displays the values (0 - 255, see sample below) read from different 
sensors within the printer, where: 
 
THR TRAN RIBM 24V
103 091  009 171
PS HD RANK
003 255 050 
 
THR = Printhead thermistor sensor;  
TRAN = Transmissive (gap) media sensor (TRAN is replaced with REFL 
when the SENSOR TYPE is set to ‘reflective’); 
RIBM = Ribbon sensor; 
24V = 24 volt power supply sensor; 
PS = Present sensor; 
HD = Printhead position sensor; and,  
RANK = Printhead ranking resistor.  
 
 
RIBBON SENSOR 
LIMITS 
 
Displays the values from the ribbon sensor readings (see example below) 
for printers equipped with the thermal transfer option: 
 
RIBBON ADC LOW 
111 
RIBBON ADC HIGH 
249
