Methods for Providing a Transferable Page Countdown for a Toner Cartridge Between Image Forming Devices

A method for providing a page countdown for a replaceable toner cartridge according to one embodiment includes, upon detecting a toner cartridge that is out of usable toner, determining a number of pages remaining for a page countdown associated with the toner cartridge. Whether a toner sump of an imaging unit positioned to receive toner from the toner cartridge contains sufficient toner to print the number of pages remaining is also determined. If the toner sump of the imaging unit contains sufficient toner, the page countdown continues from the number of pages remaining. If the toner sump of the imaging unit does not contain sufficient toner, the number of pages remaining for the page countdown is reset based on the amount of toner available in the toner sump of the imaging unit and the page countdown continues from the reset number of pages remaining.
