Interpretation
What this message does — and does not — prove
Official meaningBrother defines this as paper jammed inside the machine.
Do not assumeDo not pull blindly around hot or delicate internal parts.
Safe sequence
Work through the manufacturer-scoped path
- 01
Allow hot internal parts to cool as Brother instructs.
- 02
Open the front cover and remove the toner cartridge/drum assembly as one unit.
- 03
Pull jammed paper slowly so fragments are not left behind.
- 04
Reinstall the assembly, close the cover and print a single test page.
Stop / escalate
When not to keep experimenting
If paper is not visible or the message remains, use Brother support rather than probing the fuser or sensors.
