'Replace Drum' / 'Drum End Soon' explained

The drum is separate from the toner on a Brother laser. “Drum End Soon” is a warning; “Replace Drum” means it's at the end of its rated life. You can keep printing and reset the counter after a real swap.

01 · Identify — does this match what you see?

  • “Drum End Soon” on the panel
  • “Replace Drum” with repeating marks down the page
  • You just installed a new drum and the message persists

02 · Resolve — follow in order

  1. 1

    Confirm it's the drum, not toner: repeating black spots or streaks every ~94 mm mean a worn drum surface.

  2. 2

    Open the front cover, pull out the drum-and-toner assembly, and separate the toner from the drum.

  3. 3

    Install the new drum unit and reassemble toner+drum, then slide it fully in.

  4. 4

    Reset the drum counter: with the front cover open, hold “OK” or “Clear” until the menu shows the drum, then confirm “Yes”.

  5. 5

    Close the cover and print a test page to confirm the streaks are gone.

Pro tip

The drum counter is just a page counter — resetting it without a new drum hides the warning but doesn't fix a worn surface. Only reset after you actually install a new drum.
