Icon name Explanation
OK (Mid.) The print position is detectable with the media sensor.
The threshold is at the midpoint between the peak and
the baseline.
OK (High) The threshold is near the peak voltage, so the
detection of a gap or black marks 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 a more
accurate detection.)
OK (Low) The threshold is near the baseline voltage, so the
detection of a gap or black marks 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 a more
accurate detection.)
NG (1) The print position is not detectable with the media
sensor. Sensor adjustment is necessary.
NG (1)
The print position is not detectable with the media
sensor. Sensor adjustment is necessary.
(Threshold ≤ Baseline)
NG (2)
The print position is not detectable with the media
sensor.
(Calibration may enable print position detection, but it
is very difficult.)

The operation is same as
that for 8.5.9 reflective

Explanation
The calibration result is shown.
Pressing the [FEED] key returns the screen to the
media sensor selection and enables a threshold
setting.
Pressing the [RIGHT] key shows the measured
voltages.
Pressing the [ENTER]
threshold setting. (*)
The result of the fine adjusted threshold setting is
shown.
Pressing the [LEFT] key enables setting a
threshold fine adjustment value.
The function by pressing the [RIGHT] and
[ENTER] keys is the same way as above.

Pressing the [LEFT] key
returns the screen to "6b.
Judgment".
Pressing the [PAUSE],
[ENTER] or [CANCEL]
key returns the screen to
"6a. Judgment".
The threshold value is
stored in the location with
the allocation number
selected in "3.1 Allocation
