Clearing paper jams
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:
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.
