Besides ink debris, nozzle clogging can also be caused by foreign object interference, such as a curved printing medium or obstacles on the printing platform. To address this issue, Procolored has launched the Printhead Safeguard System, an advanced built-in detection system designed to promptly identify foreign objects and prevent deficient printing.
The system consists of two main components: an LED light emitter and a photosensitive receiver. It utilizes diffused photoelectric detection technology and triangulation methods for effective identification. The process works as follows: infrared light is emitted by the LED onto the printing medium, then reflected back to the photosensitive receiver and converted into electrical signals. If the signals from a foreign object exceed the preset threshold of the receiver, the protection action is triggered, and the circuit is opened to stop the printing process.
Currently, this system has been installed on the F8 Panda DTF Printer Gen-2, and it will soon be configured on the F13 Panda DTF Printer as well.
