Safe checks, in order
Start with the simplest non-invasive check. Stop as soon as the error clears; repeated resets can hide a condition without correcting it.
Let the printer cool
Wait before reaching near the fuser or internal metal parts.
Open the front cover
Remove the toner-and-drum assembly by its handle.
Pull paper slowly
Use both hands and follow the normal paper direction when possible.
Reinstall and close
Confirm no scraps remain before restoring the assembly.
Know where to stop
Internal parts can be extremely hot. Do not use sharp tools or touch the drum surface.
When to call a technician or support
Contact Brother if the message returns after the approved steps, the printer makes abnormal noise, or a cover, sensor, drum, or fuser component is damaged.
When you call, have the exact product or vehicle model, model year where relevant, the complete code or symbol, and when it appeared.
