AI Technical Summary
Technical Problem
The serial number of consumables is unstable when switching in the printer and is easily affected by false power-on or glitch signals, resulting in unstable authentication.
Method used
Design a consumable chip that includes a power-on detection unit, a storage unit, and a serial number switching unit. By detecting the power-on status and authentication results of the printer, dynamically update the status information in the storage unit and switch the consumable serial number to ensure stable authentication.
Benefits of technology
This improves the stability of consumable serial number switching, avoids the effects of false power-ups and glitches, and ensures the accuracy and continuity of consumable serial number authentication.
