AI Technical Summary

Technical Problem

In existing technologies, the vibration of label paper can lead to partial misdetection between label sections, making it difficult to accurately distinguish between the label section and the gap section, thus affecting the detection accuracy of the printing system.

Method used

The paper feed is controlled by a conveying control unit, the reflected light is detected by a sensor, the moving average calculation unit calculates the moving average of the voltage value, and the judgment unit judges the part between the label parts based on the moving average and the sensor output. By setting a threshold and a dot/line count threshold, the part between the label parts is judged, thereby reducing false detections.

Benefits of technology

This improves the accuracy of the printing system in detecting the label section and gaps, reduces false detections caused by label paper vibration, and ensures printing quality.

Abstract

A printing system includes a conveyance control section that controls a conveyance section that conveys paper on which label sections are formed at predetermined intervals; a sensor that irradiates light toward the paper conveyed by the conveyance section and detects reflected light of the irradiated light; a detection section that detects an output of the sensor; a moving average calculation section that calculates a moving average of a voltage value based on the output of the sensor detected by the detection section; and a determination section that determines a case where a portion between adjacent label sections is detected based on the moving average of the voltage value calculated by the moving average calculation section and the output of the sensor.
