Label printer with adjustable light detection system
The patent US12053994B2 describes a printer designed for printing on a continuous label body that is temporarily affixed to a belt-like liner. Central to this invention is a label detecting unit, which includes a light-emitting portion that emits detecting light and a light-receiving portion that captures this light. The control unit of the printer is responsible for adjusting the light emission output to ensure that the voltage output from the label detecting unit, when the light is received through the liner without a label, closely matches the output when there is no label body present. This adjustment is crucial for accurate label detection and printing.
Additionally, the printer features a thermal head for printing and a platen roller that holds and feeds the label continuous body. The label detecting unit is strategically positioned downstream of the thermal head and platen roller. The control unit can set and modify a threshold value to determine the end of the label, enhancing the printer's functionality. Furthermore, the printer is equipped with a cover that can be opened and closed, with a sensor to detect its status. When the cover is closed, the control unit activates the light-emitting portion to facilitate label detection and stops the feeding process once the end of the label is identified. The patent also includes a control method and a computer-readable storage medium that outlines the program for adjusting the light emission and feeding the label to ensure precise printing operations.
