Another element in xerographic copiers is the photoreceptor drum. This is the surface to which the toner adheres before being transfered to the paper. The photoreceptor has a long but finite useful lifetime and must be replaced occasionally. Some copiers/printers have drum cartridges which can be changed out by the user. The alternative would be to have a service person open the machine and replace the photoreceptor drum.
So, a drum cartridge alows the user to replace the photoreceptor drum and a toner cartridge allows the user to replenich toner supplies, both easier than before cartridges were developed for this purpose.
