Abstract
A method for providing a page countdown for a replaceable unit of an image forming device according to one embodiment includes calculating a number of pages remaining until the replaceable unit will reach the end of its life. The calculated number of pages remaining until the replaceable unit will reach the end of life is displayed on a display screen. After the calculated number of pages remaining is displayed, the displayed number of pages remaining is decreased in response to printing of pages by the image forming device, the number of pages remaining is recalculated and a discrepancy between the displayed number of pages remaining and the recalculated number of pages remaining is tracked. If the discrepancy exceeds a predetermined error threshold, the recalculated number of pages remaining is displayed and the displayed number of pages remaining continues to be decreased from the displayed recalculated number of pages remaining.
