Decolorable Toner Fixing Temperature Control

The patent applies parameter changes by dynamically adjusting the fixing temperature based on the specific toner types being used. The controller identifies the toner types (decolorable vs. non-decolorable) and sets the fixing temperature accordingly - using a first fixing temperature for decolorable toners and a second fixing temperature for non-decolorable toners. This prevents decoloration while ensuring proper fixation by matching the temperature to the toner's thermal properties.

The patent implements dynamics through adaptive temperature control that changes based on operational conditions. The fixing temperature is not fixed but dynamically adjusted according to which toners are being used. The controller monitors toner type information and modifies the fixing temperature in real-time, allowing the system to adapt between different temperature regimes (first fixing temperature for decolorable toners, second for non-decolorable toners) to prevent decoloration while maintaining fixation reliability.

The patent transforms the static single-temperature system into a dynamic multi-temperature system. The controller automatically identifies which toners are being used (decolorable or non-decolorable) and selects the appropriate fixing temperature accordingly. This dynamic adaptation maintains image quality consistency across different toner types while keeping the user interface simple, as the temperature selection is automated based on toner type detection.

The system changes the fixing temperature parameter based on the detected toner types. When decolorable toners are detected, the controller uses a first fixing temperature that is lower than the preset decoloring temperature to prevent decoloration. When non-decolorable toners are used, a second fixing temperature can be applied. This parameter adjustment ensures image quality consistency across different toner compositions without complicating user operation.
