(Cont.)
NOTE:
To make a threshold value set
in this section effective, select
the Transmissive Sensor (when
using pre-printed media) or
Reflective Sensor (when using
manual threshold value) in
Issue Command or the printer
driver.

Explanation
Result: OK (Mid.)
Threshold is at the midpoint between the
peak and the baseline.
Result: OK (High)
Threshold is near the peak voltage, so
detection of a gap/black mark may fail if the
voltage difference is very small. Adjusting
the threshold to the midpoint between the
peak and the baseline enables more accurate
detection. Follow next (5) to (10)
Result: OK (Low)
Threshold is near the baseline voltage, so
detection of a gap/black mark may fail if the
voltage difference is very small. Adjusting
the threshold to the midpoint between the
peak and the baseline enables more accurate
detection. Follow next (5) to (10)
Failed (1)
The media sensor cannot detect a gap/black
mark. Sensor adjustment is required.
(⇒Section 2.11)
Failed (1)
The media sensor cannot detect a gap/black
mark. (Threshold ≤ Baseline) Sensor
adjustment is required. (⇒Section 2.11)
Failed (2)
Detection by the media sensor is disabled.
Sensor adjustment is required. (⇒Section
2.11)
