Clearing Paper Jams
If a paper jam occurs, printing stops and an error message appears on the control panel informing you 
of the location of the paper jam.
To clear the paper jam, read the error message, refer to the appropriate section below, and follow the 
procedure.
Attempting to print while there is paper jammed in the printer may damage the printer. Remove 
jammed paper immediately.
■The illustration above shows the printer with the two optional lower trays, duplex unit, and offset 
catch tray installed.
■If the jammed paper is removed without opening the top cover, you still need to open and close 
the top cover. Doing this will remove the error message.
■Paper jams could be due to the printer installation environment and type of paper used. For 
details on selecting the appropriate location to install the printer, see Safety Precautions on page 
-XIX. For details on selecting the correct type of paper, see Suitable and Unsuitable Paper 
Types on page 2-1.

■When removing paper jams, make sure that no pieces of paper are left inside the printer, as this 
can cause a fire. If the paper is wrapped around the fuser or roller, or you cannot see the jam 
you are trying to clear, do not attempt to remove the paper by yourself, as this may cause injuries 
or burns. Turn the printer off immediately and contact your dealer or Brother Customer Service.
■Never touch an area indicated by a high-temperature warning label (on or near the fuser unit). 
Touching these areas may result in burns.
■If smoke comes out of the printer when a paper jam occurs, do not open the printer covers. Turn 
the printer off, remove the power cord from the AC outlet/socket, and contact your dealer or 
Brother Customer Service for assistance.
■Remove jammed paper slowly and carefully to avoid tearing it.
Paper jams can be caused by incorrect printer installation, or using unsuitable or low-quality paper. 
For details about the types of paper suitable for printing, see Suitable and Unsuitable Paper Types 
on page 2-1.
