Abstract
Image fix level and Input Output Terminal (IOT) faults are minimized. The foregoing are effected by reducing fuser roll temperature sag or droop which can be a problem during the initial portion of a copy run. A heated fuser member is operated at a higher power level during the initial portion of a print cycle. This is effected using an existing controller without modifying the controller's hardware. The foregoing is accomplished by detecting voltages values applied to the fuser member, storing these values corresponding to fuser operating parameters in a LUT, detecting elapsed time from the start of a print cycle, using the operating parameters corresponding to the detected voltage during a portion of the print cycle, and determining the difference between a detected voltage and a predetermined voltage value and using the fusing operating parameter corresponding to this difference during the initial portion of the print cycle in accordance with elapsed time.
