What is the difference between the toner cartridge and the drum unit? What’s the transfer belt unit and waste toner box?
If you own a laser printer, you should definitely be aware of the difference between a toner and a drum unit, to make sure you are buying the correct consumables for your printer.
Most laser printer’s drum and toner is one part (Eg HP/Canon), all you need to buy is the toner cartridge. Whereas others are assembled, installed and sold separately (Eg Brother/Samsung), in which case you might be confused about what to buy.
What is a toner cartridge?
The toner cartridge contains powder (toner) used for creating letters and images. You need to replace the toner cartridge when the toner is running short or print quality becomes poor because of toner deterioration.
Example:
Toner Cartridge MLT-D116L for Samsung Monochrome Printer SL-M2885FW.
Toner Cartridge Pack CLT-409S Combo Set for Samsung Color Laser Printer CLP-310.
What is a drum unit?
The drum unit transfers the toner to the paper. 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 the toner to the paper by heat and pressure.
Please be aware that drum unit is also consumables and it has limited page yield, you will need to replace it when your printouts appear excessively blackened, or you get a warning message asking you to replace drum. Usually, a drum unit can last 3-4 times longer than the toner.
Example:
Drum Unit MLT-R116 for Samsung Monochrome Printer SL-M2885FW.
Drum Unit CLT-R409 for Samsung Color Laser Printer CLP-310.
What is a Belt Unit?
Some color laser-class printers use a rotating belt called a “transfer belt unit” to further color registration accuracy. It is a rotating belt that is typically large which carries the mixture of different colors of toner particles. The cartridges will then precisely apply each toner layer to the belt which will then apply the combined layers uniformly onto the paper. You might need the belt unit to be replaced after some time of use. A belt unit is usually located under the toner and drum.
Please be aware that Samsung highly recommends that this maintenance be performed by an authorized service provider.
Example:
Belt Unit JC96-04840A for Samsung Color Laser Printer CLP-310.
What is a waste toner box?
A waste toner box collects waste powder. Any powder that is left over from the print process is collected into the box. Once the waste toner box is full, the printer will stop working until you have it replaced.
Example:
Waste Toner Box Samsung CLT-W409 for Samsung Color Laser Printer CLP-310.
