Clearing paper jams

Note

• When removing paper that is jammed in the printer, if possible always pull the paper in the direction that it normally moves so as not to damage internal components. Always pull firmly and evenly; do not jerk the paper. If the paper tears, ensure that all

fragments of paper are removed; otherwise a jam will occur again.

When a paper jam occurs, the Status LED lights red. Open and close the top cover. The jammed paper automatically exits the printer.

If the paper does not exit, check the display on the control panel. The message indicating the corresponding location of the paper jam appears. Refer to the table below to locate the paper jam and to clear it:
