5.4 Threshold Setting 
E5- 4 
5.4 Threshold Setting 
 
To maintain a constant print position the printer uses the Transmissive 
Sensor to detect the gap between labels by measuring the amount of 
light passing through the media.  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 a minimum threshold can 
be set for the sensor in the following way.  
 
„ Threshold setting procedure 
 
1.
  Turn the power ON.  The printer is in stand by mode. 
 
 
 
2.
  Load a pre-printed media roll. 
3.
 Press 
the 
[PAUSE]
 key. 
 
 
 
4.
  The printer enters the pause mode. 
5.
  Press and hold the 
[PAUSE]
 key for at least 3 seconds in the pause 
state. 
 
 
 
6.
  The sensor type is displayed. 
7.
  Select the sensor to be adjusted by pressing the 
[FEED]
 key. 
 
 
 
 
 
 
 
 
 
8.
  Press and hold the 
[PAUSE]
 key until more than 1.5 labels (tags) 
have been issued.   
 
The media will continue to be fed until the 
[PAUSE]
 key is 
released.  (Threshold setting for the selected sensor is completed by 
this operation.) 
 
 
 
9.
 Press 
the 
[RESTART] 
key. 
 
 
 
10.
  The printer is in stand-by. 
11.
  Send an issue command from the PC to the printer.

NOTES: 
1.  If the 
[PAUSE]
 key is 
released within 3 seconds 
while in the pause state, the 
paper will not feed. 
2.  Failure to feed more than 
1.5 labels may result in an 
incorrect threshold setting. 
3.  While the Print Head Block 
is raised, the 
[PAUSE]
 
key 
does not work. 
4.  A paper end error cannot be 
detected during paper feed. 
5.  Selecting the Transmissive 
Sensor (for pre-printed 
labels) within software 
commands allows the 
printer to detect the proper 
print start position even 
when using pre-printed 
labels. 
6.  If using the Transmissive 
Sensor and the printer 
continues to print out of 
position even after setting 
the threshold, contact a 
TOSHIBA TEC service 
representative.
