Thermal print head temperature is out of
range.
The print head may overheat when printing
in a room where the temperature is above
the recommended operating temperature
or when printing high-density graphics
continuously, regardless of the room
temperature. In either case, the printer will
shut o. If the temperature of the print
head is too hot, adjust the room

cooler location. If the print head is
overheating because of printing high
density graphics continuously, reduce the
demand on the printer.

indicate that the thermal print head is too
hot, the power supply voltage is out of
range. Contact your regional HP authorized
