Printers are a commonly used equipment in offices, so many manufacturers of office equipment will develop and innovate for printers, making them more intelligent and providing office work efficiency. In the working process of printers, photoelectric switches play an indispensable role. So, what are the main functions of photoelectric switches and reflective photoelectric sensors on printers?
The working principle of a photoelectric sensor is to convert the measured state into an optical signal, which is then converted into an electrical signal output through photoelectric elements. Reflective photoelectric switches can detect both the vacancy of printing paper and the position of ink cartridges in inkjet printers.
1. There is usually a small protrusion on the front or back cover corresponding to the position of the front and rear cover sensor switch, and the Omron photoelectric switch EE-SX1106 is installed here. Of course, the model will be determined based on the slot spacing. (The following models are available for everyone to choose from) And it mainly serves the purpose of stopping the printer if the front and back covers are not tightly closed. Because if the front and back covers are not tightly closed, there may be light leakage during printing or copying, which can affect the printing and copying results.
2. The paper feeding sensor will use a reflective photoelectric switch, which mainly detects the paper size and ink
