The Brother DR-400 toner drum is equipped with an internal cleaning wire that is designed to keep the drum parts clean and free of debris. The internal parts sometimes become too dirty to be cleaned by the automatic cleaning wire after heavy use. In these instances, clean toner and debris from the internal components of the toner drum assembly manually.

Things You'll Need

  • Rubbing alcohol
  • Cotton swabs
  • Phillips screwdriver

Remove the two gold screws located on the right and left sides of the top of the drum cartridge.

Pry the four retaining clips outward with a flat-blade screwdriver. There are two clips on each side of the drum cartridge.

Lift the top cover off of the drum cartridge.

Saturate the tip of a cotton swab with rubbing alcohol. Clean the corona wire with the cotton swab.

Replace the top cover on the drum cartridge. Press on the cover until the retaining clips snap into place.

Replace the gold screws on the top of the cartridge cover.
