摘要： A method of controlling a charging potential of an organic photoconductive cell (OPC) includes a first operation of applying two charging voltages Vc1 and Vc2 having respective duties D1 and D2 established in an engine controller unit (ECU) to a conductive roller via a high voltage power supply (HVPS) to charge the OPC, a second operation of measuring sensing voltages Vs1 and Vs2 through a sensing resistor Rs coupled to the conductive roller so that the ECU establishes a target charging current it and calculates a new charging voltage Vc3 and a new duty D3, a third operation of applying the new charging voltage Vc3 and the new duty D3 to the conductive roller via the HVPS to charge the OPC and measuring a charging current Ic3 of the conductive roller, and a fourth operation of comparing a difference between the charging current Ic3 of the conductive roller and the target charging current It with a tolerance value TOL to control the charging potential by using the target charging current when the difference is smaller than the tolerance value TOL. The method maintains the charging potential by compensating for a residual potential of the OPC, thus improving a performance of a printer.

摘要： 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.
