When you are shopping for toner cartridge online, you usually will find drum unit and toner cartridge. What is the difference between the two? And what should we buy?
At first, we have to figure out toner cartridges and drum unit.
Toner cartridge like TN660/TN630, are fairly simple pieces of equipment. They are essentially a plastic casing that contains the toner powder.
Drum unit Like DR630 is an electrically charged cylinder that transfers that toner powder to paper to create out text and images. Without a drum unit, the toner powder in the cartridge cannot be transferred onto the page. The two parts work together to create a print! You can’t have one without the other and expect the printer to work properly.
Both of these components are essential for printer. Toner cartridges contain a finite amount of toner powder, so they can only print a limited amount of pages. While A drum unit usually only needs to be replaced after about 3-4 toner cartridges have been replaced, and some drum units can last a little longer. For example, Brother HL-3040CN is a color digital printer; so it needs four different color toner cartridges and drum unit. Its black cartridge has an approximate page-yield of 2200 pages, the three other colors such as cyan, magenta and yellow can yield 1400 pages, while the drum units can deliver 15,000 pages. With these figures, you can now determine which among these two consumables can certainly last longer.
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.
Buying a new toner/drum combination every time ensures your print quality is consistent throughout the life of your printer, but that premium cost adds up, especially if those cartridges are upwards of a hundred dollars. The price breakdown of a separate toner and separate drum unit is slightly different. Separate toners are generally less expensive since you are just paying for the container part that holds the toner powder. The technology is not quite as complex as a toner/drum combination cartridge, so it doesn’t cost as much to produce.
