This Brother DR-5500 Drum Unit  is especially designed for use in Brother printers, ensuring that they produce quality printouts. This is easy to install so you can do it yourself.  

A small office can improve the quality of its documents and monochrome images if the laser printer is equipped with a genuine Brother DR5500 black imaging drum unit. Black text and images appear a lot more clearly when the old and ineffective drum is removed from the printer and a new Brother DR5500 image drum is installed. Text and graphics are printed more consistently without jagged edges, blurriness, and faint details when a replacement Brother DR5500 black image drum is used. You'll know when a Brother DR5500 image drum needs to be replaced when dark spots or lines appear on the pages, and the images start looking lighter, especially if you're using a fairly new toner cartridge. On average, the Brother DR-5500 drum cartridge will need to be replaced every 40,000 pages.

100% warranty. 

Easy to install and exceptional print quality time after time print after print.
