Abstract:
1. A method of determining a variable ratio value of a first imaging oil having a first percent purity in a segregation tank and a second imaging oil having a second percent purity in a reservoir in an image forming system, the method comprising: identifying a first slope value corresponding to a first rate of flow of the first imaging oil into the segregation tank during a time interval minus a second rate of flow of the first imaging oil out of the segregation tank during the time interval by a slope identification module; identifying a second amount of a second imaging oil; determining whether the first slope value is equal to, greater than, or less than a threshold slope value within a threshold slope range by a slope comparison module; and obtaining the variable ratio value corresponding to a ratio of a first amount of the first imaging oil to the second amount of the second imaging oil by a ratio adjustment module based on a determination by the slope comparison module.
