AI Technical Summary
Technical Problem
The certification methods for consumable chips are relatively simple, lacking flexibility and accuracy.
Method used
After receiving the authentication command from the image forming device, the consumable chip selects the target response method from a variety of preset response methods and pulls the data line low for a continuous period of time to ensure that the image forming device collects a low level for the continuous period of time, thus achieving successful authentication.
Benefits of technology
This improves the flexibility of the certification process for consumable chips while maintaining high certification accuracy.

Abstract
This invention provides an authentication method for a consumable chip, a consumable chip, and a consumable container. The method includes: receiving an authentication command sent by an image forming apparatus, the authentication command carrying a duration; responding to the authentication command, within the duration, pulling the voltage level of a data line low according to a target response method selected from a preset set of response methods, so that the image forming apparatus can collect the voltage level state of the data line within the duration; and determining that the consumable chip authentication is successful when all collected data line voltage levels are low. The consumable chip can accurately pull the voltage level of the data line low within the duration of the low-level operation, thereby passing the authentication by the image forming apparatus. This improves the flexibility of the response method while maintaining high authentication accuracy.
