The drum unit is responsible for transferring toner onto the paper during the printing process. In this article, we will delve into the various aspects of the Brother MFC 9130CW drum, including its function, maintenance, troubleshooting, and replacement.

How Does the Drum Unit Work?

The Brother MFC 9130CW drum unit is an essential part of the laser printing technology used in this printer. It utilizes an electrostatic charge to attract the toner particles, which are then transferred onto the paper. The drum rotates as it passes through the toner, collecting the charged particles and transferring them onto the paper in the form of text or images.

Maintaining the Drum Unit

Maintaining the drum unit of your Brother MFC 9130CW is vital for optimal print quality and longevity. Regular cleaning is necessary to remove any residual toner, paper dust, or debris that may accumulate on the drum surface. To clean the drum, gently wipe it with a lint-free cloth or a soft brush. Avoid touching the drum surface with bare hands to prevent damage or contamination.

Common Drum Unit Issues

Like any other printer component, the Brother MFC 9130CW drum unit may encounter some common issues over time. One of the most prevalent problems is the appearance of vertical lines or streaks on printed pages. This issue usually indicates a dirty or damaged drum surface.
