1.4 Detection Functions1.4.1 Detection by sensorsThe following sensors detect the printer's condition.1.4.2 Paper-end sensorThe photo interrupter-type, paper-end sensor detects the paper with the paper sensorarm's flag when the edge of the paper passes through the paper feed section. Whenthere is no paper, the sensor is closed by the paper sensor arm. When paper isdetected, the sensor is open and paper is thereby detected.3-7S6300Part 3: Technical Reference ProductSpecificationsCarriage EncoderPaper Feed EncoderCover Sensor(SW)Purge SensorASF SensorPaper-end SensorInternal Temperature SensorFigure 3-5 Location of Sensors
