What is a Drum Unit?March 24, 2011 1 Comment
Laser printers have been considered to be efficient machines for fast and high quality prints. It is filled with a set of laser toner cartridges and a laser drum unit that are replaced once in awhile when supplies have reached their limits.
Although laser toner cartridges are already common and can be quite easy to understand for printer users, the laser drum unit is another consumable that is not talked about most of the time. To understand what a drum cartridge is all about, here are a few interesting facts.
The laser drum unit is a printer supply, that is responsible for transferring the laser toners onto the paper. It basically attracts the toner through static electricity, so some parts of the drum should be oppositely charged from the toner to allow contact. This is when the letters are formed and pressed on the paper to form the print.
The life expectancy of a laser drum cartridge depends on the model but somehow the common page yield for a drum unit would be 6,000-8,000 pages. When it comes to the type of drum unit, you can find three available kinds which are: an OEM or the original equipment manufacturer cartridge, a compatible drum cartridge, and a remanufactured laser drum unit. These three normally have the same quality and the main difference is only at the price. The last two choices can provide savings by up to 70% which can be great for budget savers.
Laser drum cartridges are indeed important for every laser printer user. Without this supply, it would seem impossible for a machine to continue its prints. So be sure to always watch out on your laser printer supplies since it can cause problems when you suddenly lose them in the middle of your printing job.
