DRUM PRINTER CARTRIDGE -WHAT DOES IT DO?
And when should I replace it?
A printer drum is a rolling pin inside of a laser/toner printer. To create image patterns, a laser beam shines on the drum in the shape of the required image (text, pictorial), to place what are called "electrostatic images." The drum is then rolled through a reservoir of toner, the powdered substance that creates printed images on the paper (for both black and coloured prints), on those previously invisible electrostatic patterns. The paper rolls through the drum, where the toner is applied, and then finally goes through what is called a fuser which is a heat source to melt the powder, to create your printout.
The drum is different to the toner cartridges, the sole purpose of which is to hold the toner powder. The drum is the unit that normally clips onto the back of the toner cartridge, and it holds the image and is extremely important to the laser printer functioning properly. When it starts to wear, you will have problems with print quality and you may experience frequent paper jams.Signs of drum deterioration:
- Smudges or marks on paper
- Faded print
- Blank areas in print
- Paper jam
Although some printers will give you a warning that you should replace your drum unit, it is a good idea to have a spare in the storage room.
Drum units include the Brother DR-150CL, DR2025, DR2125, DR2225, DR3000, DR3115, DR3215, DR6000. DR7000, and DR8000. Also the Dell 310-7042, the Epson C13S051055, the HP CB384A, and the Xerox CT350150.
