3.1 Automatic Threshold Setting
Outline of Automatic Threshold Setting
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
even if the media is not actually jammed.
To get around this problem, first, try an automatic threshold setting.
If the problem still occurs, then, the threshold voltage needs to be manually set. (Refer to Section 2.3.7.)
How to Perform an Automatic Threshold Setting
NOTES: 1. Failure to feed more than 1.5 labels may result in an incorrect threshold setting.
2. While the print head is raised, the [PAUSE] key does not work.
3. When the [PAUSE] key is released within 3 seconds while the printer is paused, no action is taken.
4. While the printer is feeding labels to determine a threshold value, no errors, including a paper end
error, is detected.
5. If the printer still does not start printing at the proper print start position after the threshold setting
operation is performed, it can be suspected that a sensor adjustment is not proper.
In this case, readjust the sensor in the system mode, then perform the threshold setting operation
again. (When the backing paper of a label paper is too thick, the transmissive sensor should be
readjusted.)
In addition, make sure that the type of sensor for Issue and Feed commands is set to “3: Transmissive
sensor (when using a preprinted label)” or “4: Lower Reflective sensor (when using a manual
threshold value)”.
