What safety precautions should I follow when using this printer?

Read and understand all instructions in the documentation. Observe all warnings and instructions marked on the printer. Unplug the printer from wall outlets before cleaning. Do not install or use the printer near water or when you are wet. Install the printer securely on a stable surface and in a protected location where no one can trip over the power cord. There are no user-serviceable parts inside—refer servicing to qualified personnel. Use only the power cord and power adapter supplied by HP.
