AI Technical Summary
Desktop barcode printers with cutters lack a safety interlock mechanism in their cover opening control, leading to interference between the cutter and the cover, damage to the media, and the risk of pinching fingers. Furthermore, the lack of linkage between cover opening and the printing process results in data loss and equipment malfunction.
By receiving and verifying the legality and validity of the lid opening trigger signal, the system obtains the position status of the printing body and the cutter in real time, determines whether the cutter has been safely reset, and performs preset timing wait and unlock operations after reset, thus verifying the lid closing status in a closed loop to ensure the reliability and safety of the lid opening and closing process.
It achieves a safety interlock between the cutter and the cover, avoiding mechanical interference and operational risks, improving the printer's operational safety and stability, reducing the probability of accidental triggering and invalid closure, and improving the user experience.
