';Toner'; is the black powder that gets printed onto the page. The toner powder is actually made of small charged particles.





The way laser printers work, and it sounds like your fax machine is using laser technology for the printing, is it charges the the toner particles into the image (the page image with text and pictures) to be printed. The charged particles are placed on a large charged roller called the ';drum';.


As the paper passes through the machine, the paper passes by the drum roller, and the drum places the toner image onto the paper.





There's also another step. The toner that the drum roller places on the paper is loose on the paper. So there's another roller in the printer that's heated. This is the fuser roller that heats and melts the toner so it ';fuses'; onto the paper so it sticks on there.





A ';cartridge'; is just the container that contains the drum roller and toner inside of it.





Toner cartridges are expensive. So what your boss is saying is that instead of buying a whole new cartridge, is to just send it off to refill it with toner.





For some printers, the drum is separate from the toner cartridge, so you don't have to buy a new drum+toner cartridge at the same time. In this case, you only pay for the cartridge that as the toner in it.
