What is difference between drum & toner cartridge?

Hi,
Would it be possible for someone to explain to me the difference between a 'toner cartridge' and a 'drum' for a laser printer? Do I need both for the printer to function and will I have to replace both in the same frequency?
Thanks very much!

Howdy:

Webopedia can probably explain it best..

"A type of printer that utilizes a laser beam to produce an image on a drum. The light of the laser alters the electrical charge on the drum wherever it hits. The drum is then rolled through a reservoir of toner, which is picked up by the charged portions of the drum. Finally, the toner is transferred to the paper through a combination of heat and pressure. This is also the way copy machines work."

So, the drum is what holds the image itself.. the toner cartridges hold the black and color toners that are transferred to the drum..

You will probably go through more toner than you will drums !!

Another good explanation site..

If the machine has separate drum and toner cartridges you will get at least three toner cartridges per drum and sometimes much more. The drums generally cost about 3 to 4 times as much as a toner cartridge. As stated by Murray S., the toner cartridge is just that, a cartridge holding the toner. The drum does the work. Some machines have a combination drum/toner cartridge that is cheaper than the stand alone drum units but more than the toner cartridges alone. If buying a machine it is best to look for one that has a separate toner cartridge/drum arrangement. When buying a machine be sure to check which arrangement it has, the cost of the cartridges and very importantly, the yield of the cartridges. Many will have a choice of standard or high yield cartridges. The high yield are always a much better deal. Try to get a machine that gives a high yield toner cartridge of at least about 6000 pages per cartridge. Realize that the estimated yields are some sort of monkey math as you will never get the advertised amount. If you get a machine that is low cost but only has cartridges that are advertised to yield only about 1500 pages per cartridge, you will be paying more in the long run for your prints.

The drum is a waste collection unit. It is a consumable part and will need to be replace when your print appear excessively blackened, or you get a check drum warning.

The drum clips onto the back of the toner. It usually for about three times as many pages as the toner. Thus if you have replace the toner a cuple of times and nut the drum, it is time.

A drum will usually run you around the cost of a new toner cartirdge. They can be found in third party and remanufactured brands.
