• The label length to be returned includes the gap between labels.
• The label pitch size to be returned will show the value of last label that passes over the sensor.
Therefore label will exist in between head and sensor with a short pitch label, and it may not be
equal to the printed/ejected label's pitch size. The minimum label length would be 70 mm.
• This is available only when sensor is enabled. Returns "000000" when sensor is disabled.
• If there is a missing label in the roll in using gap sensor, the valid label length and the distance
for the missing label are added together to be returned depending on sensor level.
• The label length detected by the printer includes around the same amount of tolerance as print
precision.
• Print speed and print darkness gives little or no affect to the detected label length. However it
may vary if you change print speed depending on the sensitivity of the sensor.
• Label length is measured once again at FEED when the sensor type is switched from LCD
menu. When you send DC2+PN command the label length before switching is returned. Then,
printer returns the unfinalized 0 dot in the first FEED, followed by the re-measured label length
at the 2nd FEED. And label length may vary depending on the characteristic of the sensor.
[Coding Example]
Get label length by feeding 2 labels
<A>
<IK>0 Feed 1
<Z>
<A>
<IK>0 Feed 2
<Z>
Feed completed ←Label length is finalized here
DC2+PN Request label length
Feeding necessary number of labels has been completed ←Label length is measured by each label and
then finalized
DC2+PN Request for label length←You can get the latest label length
The correct label length is returned if you feed twice manually and request with DC2+PN after
setting label, even without using <IK>0 command.
