2.PRINTER SETUP 2.10 Threshold Setting 2.10 Threshold Setting (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. Display example 1 2 3 4 5 6 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) (5) To return to the sensor selection screen, press the [FEED]. To terminate the threshold setting, press the [ENTER]. To see the details, press the [RIGHT].
