Brother TN660 Toner vs DR630 Drum, What's the difference?



Some printers use a separate toner and drum unit, while others do not. Depending on what printer you own, you might have replaced your drum unit occasionally, or you may have never had to replace a drum unit. It is all contingent on the design of your printer. 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.

Laser printers 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. Most brother toner cartridges have a separate design, such as Brother tn660 toner cartridge and dr630 drum unit.


What is Toner Cartridge?



Toner cartridges contain a finite amount of toner powder, so they can only print a limited amount of pages. You need to replace the toner cartridge when the toner is running short or print quality becomes poor because of toner deterioration. TN660 toner cartridge usually use together with DR630 drum unit.


What is Drum Unit?



Drum unit is just a shelf and did not contain toner powder, therefore, you need to add the toner cartridge into the drum unit before you use it.

The drum unit has longer service life than the toner cartridge. It usually only needs to be replaced after about 3-5 toner cartridges have been replaced. Some drum units can last a little longer. The laser printer puts the toner on the roller called "The photosensitive drum" inside the drum unit, and then prints letters and images by fixing toner to the paper by heat and pressure. 


What is Toner and Drum Combo Pack?

When do you need to replace?

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.

In addition, you can also check the usage of toner cartridges and drum units by printing a self-test page. The printer will also prompt you to replace the toner cartridge or drum unit when it is exhausted.

With a separate toner cartridge and drum unit, the initial cost of the toner cartridge is cheaper and you can replace the toner cartridge at a cheaper price without paying the added price of the drum unit being included, which doesn’t need to be changed as frequently as the toner cartridges. 

Some toner cartridges do come with the drum unit combined as a single unit, like the HP CF283X toner cartridge. The drum unit is likely incorporated into the toner. Therefore, there is no need to replace the drum separately. With one toner and drum component, you don’t have the inconvenience of having to monitor and replace two separate parts.
