NOTE
Warning! If the printer has been printing, the fuser will
be HOT!
To remove a sheet trapped in the fuser, grasp the edge
of the sheet, push the fuser pressure release lever (1)
towards the front and down, and lift out the sheet. Then
let go of the fuser pressure release lever.
If the sheet is well advanced into the fuser (only a short
length is still visible), do not attempt to pull it back. See
step 4 under "Jam 382" .
