What is the 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 toner to the paper by heat and pressure.

To ensure printing quality,laser printers detects the deterioration of the drum unit automatically. If your printer displays an error message to replace your drum, you need to replace the drum unit. Some manufacturers drum units may not give this replace drum warning.

When do I have to replace the drum unit?

If the image of your document is repeated on the page (such a ghosted image) or when the printing is noticeably lighter or blurrier than usual it is time to replace the drum unit. Drum units like toner cartridges have a life expectancy, e.g. If for your machine you use a toner cartridge that yields 6,000 pages and the drum unit has a life expectancy of 20,000 pages then after you have used 3 toner cartridges you should expect the drum to be changed during the life of the fourth cartridge.

Do I have to replace the toner too when the drum needs replacing?

If the drum unit comes to the end of its life expectancy, separate the toner cartridge and drum unit and replace the the Drum only. Toner cartridges are a sperate entity on units with seperate drums and do no have to be replaced together.

A number or machines today incorporate the drum into the cartridge so replacing individual items are not possible. If you experiance the same systems in an all in one cartridge both the toner and drum will be replaced as one.
