Interpretation
What this message does — and does not — prove
Official meaningBrother says paper is jammed in the back of the machine.
Do not assumeA rear jam after one damaged sheet does not establish a failed fuser.
Safe sequence
Work through the manufacturer-scoped path
- 01
Let the printer cool as directed.
- 02
Open the rear cover/fuser cover using Brother's procedure.
- 03
Remove the sheet slowly and check for torn fragments.
- 04
Close covers completely and retry with known-good supported paper.
Stop / escalate
When not to keep experimenting
Repeated rear jams with clean paper and a clear path should move to Brother's feed/fuser service path.
