2.10 Threshold Setting

E2-67  

To maintain a constant print position the printer uses the media sensor to 
detect a print start position according to the difference of voltage between 
a print area and a gap or black mark.  When the media is pre-printed, the 
darker (or more dense) inks can interfere with this process causing paper 
jam errors. 

To get around this problem, first, try an automatic threshold setting.   
If the problem still occurs, then, the threshold voltage needs to be fine 
adjusted.  

Threshold is a voltage level by which the printer determines whether a 
print area or a gap/a black mark is being detected by the media sensor.   
The threshold is a boundary between a print area and a gap/black mark, 
and should be a midpoint of their voltage levels. 

(1)  Load the media to be used.  
(2)  Choose 1) or 2) depending on the sensor type to be used, then press 

the [ENTER].  

 

 

 
(3)  Hold down the [PAUSE] until more than 1.5 labels (tags) have been 

fed.   

 

The media will continue to be fed until the [PAUSE] is released. (An 

automatic threshold setting for the selected sensor is completed by 

this operation.) 

 

 

(4)  The result of the threshold setting is displayed.
