2.PRINTER SETUP

2.10 Threshold Setting

Power ON
Power OFF
NOTES:
1. Failure to feed more than 1.5
labels may result in an
incorrect threshold setting.
2. Ensure that a paper end or
ribbon end error will not
occur during paper feed.
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.

Threshold Setting Mode
(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.
