Follow the procedure below when you do not need to use the printer for a long
period.
1.
On the printer's right side, press the
side of the power switch marked [O] to
turn off the printer.
2.
Disconnect the power cord, interface
cable, and any other cables.
Never touch a power cord with wet hands.
This constitutes an electric shock hazard.
When unplugging the printer, grasp the plug
instead of the power cord. Forcibly pulling the
power cord can damage it and cause fire or
electric shocks.
3.
Remove the paper from the paper tray,
and store it in a dry, dust-free place.

printer and try removing the paper
again.
