The DR-5500 original drum unit was developed for your printer and reliably delivers excellent printing results. The high print quality of the DR-5500 is based on the perfect coordination with the laser printer, which ensures a clean and high-quality print image. Another special feature of Brother laser devices is that the original Brother toner cartridges are not permanently installed in the respective drum. The reason for this is that the wearing parts of the drum have a longer lifespan than the powder in the toner cartridges. Thanks to the separate toner/drum system, the drum can continue to be used even after the cartridges are empty and you only ever have to replace the component that is actually empty or worn out. This way you can save printing costs and protect the environment. By choosing an original DR-5500 drum unit, you ensure that your Brother machine functions optimally and is still protected by the 3-year guarantee.
