6.6 MANUAL THRESHOLD SETTING
6.6.1 Outline of Threshold setting
When a label stock is printed, the printer automatically corrects the print position by detecting gaps between
the labels by using the transmissive sensor to maintain a constant print position. However, when preprinted
label stock is used, print positions may not be detected correctly depending on ink type used for preprints. In
this case, it is required to manually set the transmissive sensor threshold through key operations and store the
value in the non-volatile memory.
This threshold stored is used for printing by selecting “3: Transmissive Sensor (when using the preprinted
label)” for the sensor type of the Issue Command, and data is printed at a constant print position correctly
since the print positions are detected based on this threshold.
When the media with black marks printed on the back side is used, the printer automatically corrects the print
position by detecting the black marks by using the reflective sensor. However, if there is reflective rate
variation on the media except for the black marks, the print position cannot be corrected properly. In this case,
it is required to manually set the reflective sensor threshold through key operations and store the value in the
non-volatile memory.
This threshold stored is used for printing by selecting “4: Reflective Sensor (when using a manual threshold
value)” for the sensor type of the Issue Command, and data is printed at a constant print position correctly
since the print positions are detected based on this threshold.
