Safety precautions
Follow at all times the precautions and warnings below to use the printer safely. Do not carry out any
operations or procedures other than as described in this document, because doing so may result in death,
serious personal injuries, or fire.
Mains connection
● Use the power supply voltage specified on the label. Avoid overloading the printer’s electrical outlet
with multiple devices. Doing so can cause a fire or an electric shock hazard.
● Ensure that the printer is well grounded. Failure to ground the printer may result in electrical shock, fire,
and susceptibility to electromagnetic interference.
● Use only the power cord supplied by HP with the printer. Do not damage, cut, or repair the power cord. A
damaged power cord can cause fire and electric shock. Replace a damaged power cord with an HP-
approved power cord.
● Insert the power cord securely and completely into the wall socket and printer inlet. A poor connection
can cause a fire or an electric shock hazard.
● Never handle the power cord with wet hands. Doing so may cause electric shock hazard.
● Observe all warnings and instructions marked on the printer.
Printer operation
● Do not allow metal or liquids (except those used in HP Cleaning Kits) to touch the internal parts of the
printer. Doing so may cause fire, electric shock, or other serious hazards.
● Never insert your hand into the printer while it is printing. Moving parts inside the printer may cause
injuries.
● Keep the ventilation system in the room turned on when printing.
● Unplug the printer from the wall before cleaning.
Printer servicing
● There are no operator-serviceable parts inside the printer. Refer servicing to qualified service
personnel. Contact your local HP Support (see Contact HP Support on page 191 ).
● Do not disassemble or repair the printer yourself. There are hazardous voltages inside the printer that
can cause a fire or electric shock hazard.
● Internal fan blades are hazardous moving parts. Disconnect the printer before servicing.
Caution
Turn off the printer and unplug the power cord from the power outlet in any of the following cases:
● If there is smoke or an unusual smell coming from the printer
● If the printer is making an unusual noise not heard during normal operation
● If a piece of metal or a liquid (not part of cleaning and maintenance routines) touches internal parts of
the printer
● During a thunderstorm
● During a power failure
● The power cord or plug is damaged
