● Jam Error Codes (J Code)
NOTE: ● The J## Code indicates the most probable Jam location. If the jam message reappears after the jam is cleared,
paper is most likely jammed at other location(s). Check the Jam Error Codes Table above for other check points
and remove all misfed paper.
● Make sure that the Jam Error Code disappears after removing the misfed paper.
● The Jam Error Code will not disappear if the paper is still jammed in the machine. Check again and remove all
misfed paper.
