The toner cartridge is the container that holds the toner power. The drum unit is an electrically charged cylinder that transfers that toner power to paper to create out text and images. Both of these components are essential for producing a print. Depending on what printer you own, you might be used to replacing your drum unit occasionally, or you may have never had to replace a drum unit. Toner cartridges contain a finite amount of toner powder, so they can only print a limited amount of pages. A drum unit usually only needs to be replaced after about 3-4 toner cartridges have been replaced; some drum units can last a little longer.
It is all contingent on the design of your printer whether a drum unit can be incorporated with the toner cartridge or sold separately as a single unit depending on the consumable requirements of your printer and their consumables vary across printer models. Some printers only need you to replace the toner cartridge, and others require that you regularly replace both the toner cartridge and the drum unit. Consult your printer’s user manual to determine what consumables are appropriate for your machine.
Which one do I buy?
Generally, your printer will let you know if the toner cartridge or the drum unit needs to be replaced. If your printer doesn’t let you know that the toner cartridge or drum unit needs to be replaced, you can check the quality of the prints. If the prints you are getting are faded, you will need to replace your toner cartridge. If you are getting blank spaces or streaks in your print, you will need to replace the drum unit. The best way to determine whether your printer needs a separate drum unit is to check the user manual. The user manual will usually have a list of which printer consumables you need. All Brother Toner, OKI toner and Xerox toner printers have a separate drum unit and toner cartridge, while only some Samsung toner, HP toner, Canon toner and Lexmark toner printers will need you to buy both.
