6.4 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 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. To select the Reflective Sensor (Black Mark Sensor), press the
[FEED] key.
8. To select the Transmissive Sensor (Feed Gap Sensor), press the
[FEED] key again.
9. Press and hold the [PAUSE] key until more than 1.5 labels (tags)
have been advanced.
The media is advanced until the [PAUSE] key is released.
(Threshold setting is completed by this operation.)
10. Press the [RESTART]
key.
11. The printer is in stand-by.
12. Send an issue command from the PC to the printer.

NOTES:
1. If the [PAUSE] key is
released within 3 seconds
while in pause state, 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. Errors such as paper end
and cutter error are not
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
correctly 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, adjust the
Feed Gap Sensor in the
system mode. Reset the
threshold again. Make sure
that the Transmissive
Sensor (for pre-printed
labels) is selected in the
feed and issue commands.
