Abstract: PURPOSE: A method for controlling electrification potential of a conductive roller is provided to regularly maintain electrification potential of a photo conductive cell regardless of an electrification of the photo conductive cell, thereby improving the printer performance. CONSTITUTION: A photo conductive cell is electrified by applying two electrification voltages and duties set in an engine controller to a conductive roller through a high voltage power supply(101-104). A target electrification current is set in the engine controller by measuring a sensing voltage of a sensing resistance, and new electrification voltage and duty are calculated(105-109). The new electrification voltage and duty are applied to the conductive roller through the high voltage power supply for electrifying the photo conductive cell, and an electrification current of the conductive roller is measured(110-112). The electrification current of the conductive roller is compared with a difference value and a tolerance value of the target electrification current to control electrification potential by the target electrification current if the difference value is less than the tolerance value(113).

Abstract: A toner reproduction curve (TRC) control method is provided. The TRC method for controlling a printer including a color toner density (CTD) sensor includes the steps of (a) measuring a development potential VB, a charging potential VO, an exposure potential VR, and a development current Id and evaluating a development vector VD, which is the difference between the development potential VB and the exposure potential VR, and a backplating vector VBP, which is the difference between the charging potential VO and the exposure potential VR; (b) forming a TRC space using TRC data detected from the CTD sensor; (c) obtaining a TRC characteristic function from the TRC data, the development vector VD=x, the backplating vector VBP=y, and the development current Id=z; (d) forming an RTRC by setting TRC data, whose covariance is smaller than a threshold value among the detected TRC data, as RTRC data; and (e) measuring TRC data, comparing the measured TRC data with the RTRC data to calculate control parameter values, and controlling the printer using the control parameter values. The TRC method does not require other sensors but the CTD sensor. By using internal parameters covering environmental changes, the charging potential of a photosensitive body, a state of a developer, and the efficiency of a charger can be estimated, thereby realizing efficient TRC control.
