Abstract
An electrophotographic image forming device according to one embodiment includes a controller configured to provide a page countdown for a replaceable toner cartridge of the image forming device on a display screen. The controller, upon detecting a toner cartridge that is out of usable toner, is configured to determine a number of pages remaining for a page countdown associated with the toner cartridge. The controller is configured to determine whether a toner sump of an imaging unit positioned in the image forming device to receive toner from the toner cartridge contains sufficient toner to print the number of pages remaining for the page countdown associated with the life of the toner cartridge. The controller is configured to continue the page countdown if the imaging unit contains sufficient toner and to reset the page countdown if the imaging unit does not contain sufficient toner.
