A Brother MFC-J5855DW is a business color inkjet that handles paper up to A3 with a document feeder and multiple trays, so a paper jam message can come from several places, and the printer's display usually says where. Read the message: it names Jam Front, Jam Rear, Jam Inside or a tray. Switch the printer off, then open the covers that the message names and pull out the jammed paper gently, in the direction of travel, without tearing it.
The checks in more detail
Check every tray and the back cover, and use a flashlight and tweezers to find small scraps. The jam clearing cover at the back lifts to reveal the path. Also look under the document feeder if the jam happened during a scan or copy. After clearing, find out why it jammed. Check the paper in each tray: it should be flat, dry, the right size and set against the guides, and not over the mark. Wide paper can curl, especially from a half-used pack.
Check the paper type setting, since glossy paper needs the right tray and setting, and thick paper may need the manual feed slot. Do not mix paper types in one tray. A tray that is not pushed in fully or a cover that is not closed leaves the paper path open, and the printer shows a jam. The pickup rollers can wear or collect paper dust, so paper does not feed or feeds crooked. Brother's manual shows how to clean them with a soft damp cloth with the printer unplugged.
If double sheets feed at once, fan the stack before loading, and keep the paper dry. A recurring jam in the same place points to an obstruction, a bent part or a dirty roller there. Print a test page after clearing to check. If the jam message continues with an empty path, a sensor may be stuck; switch the printer off for a minute and back on. Contact Brother with the model number if jams persist with good paper and clean rollers.
