electrical parts) while the printer is working.
■ In case of trouble do not attempt to repair the printer. Ask Citizen
Systems service for repair.
■ Be careful that the printer cover does not entrap your hands or fingers.
■ Be careful with sharp edges on the printer. Do not allow them to
injure you or damage property.

immediately abort the current print session and unplug the printer from
the supply outlet.
