2.PRINTER SETUP2.10 Threshold SettingE2-592.10 Threshold Setting(Cont.) Display example Explanation1 Result: OK (Mid.)Threshold is at the midpoint between thepeak and the baseline.2 Result: OK (High)Threshold is near the peak voltage, sodetection of a gap/black mark may fail if thevoltage difference is very small. Adjustingthe threshold to the midpoint between thepeak and the baseline enables more accuratedetection. Follow next (5) to (10)3 Result: OK (Low)Threshold is near the baseline voltage, sodetection of a gap/black mark may fail if thevoltage difference is very small. Adjustingthe threshold to the midpoint between thepeak and the baseline enables more accuratedetection. Follow next (5) to (10)4 Failed (1)The media sensor cannot detect a gap/blackmark. Sensor adjustment is required.(⇒Section 2.11)5 Failed (1)The media sensor cannot detect a gap/blackmark. (Threshold ≤ Baseline) Sensoradjustment is required. (⇒Section 2.11)6 Failed (2)Detection by the media sensor is disabled.Sensor adjustment is required. (⇒Section2.11)(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].(e.g: Succeeded) (e.g.: Failed)Sensor typePeak voltageThreshold voltageBaseline voltageKey operation guideNOTE:To make a threshold value setin this section effective, selectthe Transmissive Sensor (whenusing pre-printed media) orReflective Sensor (when usingmanual threshold value) inIssue Command or the printerdriver.
