Fire fighting equipment
You must provide two fire extinguishers for the site. Make sure the extinguishers are placed where they
are easily accessible in case of fire.
●
A fire extinguisher certified for electrical fires must be in the print production area.
●
A fire extinguisher must be placed in the substrate storage area, due to the large amount of solid
combustibles (substrates).
Emergency exits and first aid stations should also be considered.
Environmental specifications
These environmental conditions must be kept within the specified ranges to ensure the correct operation
of the printer. Failure to do so may cause print-quality problems or damage sensitive electronic
components.
Table 2-3
Printer environmental specifications
Relative humidity range for best print quality
20–80%, depending on substrate type
Temperature range for best print quality
18 to 25°C (64 to 77°F), depending on substrate type
Temperature range for printing
15 to 30°C (59 to 86°F)
Temperature range when not in operation
-25 to +55°C (-13 to +131°F)
Temperature gradient
no more than 10°C/h (18°F/h)
Maximum altitude when printing
3000 m (10000 ft)
NOTE:
The printer must be kept indoors.
NOTE:
If the printer or ink cartridges are moved from a cold location to a warm and humid location,
water from the atmosphere can condensate on the printer parts and cartridges and can result in ink
leaks and printer errors. In this case, HP recommends that you wait at least 3 hours before turning on
the printer or installing the ink cartridges, to allow the condensate to evaporate.
In addition to controlling the temperature, humidity, and temperature gradient, there are other
environmental conditions that must be met during site preparation.
●
Do not install the printer where it will be exposed to direct sunlight or a strong light source.
●
Do not install the printer in a dusty environment. Remove any accumulated dust before moving the
printer into the area.
Ventilation and air conditioning
The printer produces a significant amount of heat. Adequate ventilation and air conditioning is important
in the print production area.
Power dissipation (42-in printer: 3.5 Kw, 12.3 KBTU/h; 60-in printer: 4.8 Kw, 16.4 KBTU/h) and water
vapor from drying ink may require your site to have air conditioning. Adequate conditions can be
established by air renewal if the external temperature is cold enough.
It is recommended that positive airflow be maintained in the print production room. This will help prevent
dust from entering the room.
NOTE:
The ventilation and air conditioning units should not blow air directly onto the printer.
