Brother error code Drum !
Quick answer
The corona wire on the drum unit needs cleaning. This is a cleaning prompt, not a request to replace the drum.
Caution: This step can be done wrong in a way that is costly or hard to undo, including voiding your warranty. Check your model's manual before proceeding.
Before you try the solution
- 1. Copy the complete message exactly as shown, including any letters, spaces, or punctuation around Drum !.
- 2. Find the printer's exact model number. The same-looking code can mean something different on another model family.
- 3. Let the current print, scan, or update operation stop before touching controls, paper paths, or covers.
