CAUTION—POTENTIAL INJURY: The printer weight is greater than 18 kg (40 lb) and requires two or more
trained personnel to lift it safely.
CAUTION—SHOCK HAZARD: If you are accessing the system board or installing optional hardware or memory
devices sometime after setting up the printer, then turn the printer off, and unplug the power cord from the
wall outlet before continuing. If you have any other devices attached to the printer, then turn them off as well,
and unplug any cables going into the printer.
