NOTES:
(1) When the [PAUSE] key is released within 3 seconds while the printer is paused, the [PAUSE] key is
invalid.
(2) To set the threshold, 1.5 pieces or more label shall be fed. (If the label feed amount is insufficient, the
threshold may not be properly set. In this case, the threshold setting needs to be retried.)
(3) While the print head is lifted, the [PAUSE] key is invalid even if the [PAUSE] key is held down for 3
seconds or more.
(4) When the print position is not corrected even after the threshold is set, the sensor adjustment may be
insufficient. In this case, readjust the sensor in the system mode, and set the threshold.
(When the backing paper of the label is too thick, the transmissive sensor needs to be readjusted.)
In addition, make sure that "3: Transmissive sensor (when using the preprinted label)" or "4: Reflective
sensor (when using a manual threshold value)" is selected for sensor type of the Feed Command and the
Issue Command.
(5) Paper end and ribbon end are not detected during the threshold setting. (The setting continues as long
as the [PAUSE] key is held down even if the printer runs short of media or ribbon.)
(6) The detailed result of the calibration is shown when the [RIGHT] key is pressed while the judgment result
is displayed. The measured sensor level and the currently programmed threshold fine adjustment value
can be checked.
Fine adjustment value = Peak voltage – Threshold voltage
(7) Pressing the [LEFT] key returns the detailed result to the judgment result display. Pressing the [RIGHT]
key causes the display to go to the threshold fine adjustment screen. This is the same menu with the
threshold fine adjustment menu in section 5.7.3.1 REFLECT (Reflective sensor) or 5.7.3.2 TRANS.
(Transmissive sensor).
Icon name
OK (Mid.) Print position is detectable with the media sensor.
Threshold is at the midpoint between the peak and the
baseline.
OK (High) Threshold is near the peak voltage, so detection of a
gap/black mark may fail if the difference between the
threshold and the peak voltage is very small. (Adjusting
the threshold to the midpoint between the peak and the
baseline enables more accurate detection.)
OK (Low) Threshold is near the baseline voltage, so detection of
a gap/black mark may fail if the difference between the
threshold and the base voltage is very small. (Adjusting
the threshold to the midpoint between the peak and the
baseline enables more accurate detection.)
NG (1) Print position is not detectable with the media sensor.
Fine adjustment is necessary.
NG (1)
Print position is not detectable with the media sensor
because the threshold  Baseline. Fine adjustment is
necessary.
NG (2)
Print position is not detectable with the media sensor.
(Calibration may enable print position detection, but it is
very difficult.)

Explanation
The calibration result and the threshold voltage are
displayed.
Pressing the [RIGHT] key enables setting a
threshold fine adjustment value.
Pressing the [LEFT] key returns the screen to the
