HP Designjet L25500 Printer Series - Site preparation guide (second edition)

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
As with all equipment installations, to maintain comfortable ambient levels, air conditioning or ventilation
in the work area should take into account the printer's heat dissipation. Maximum power dissipation is:
42-in printer: 3.5 Kw, 12.3 KBTU/h; 60-in printer: 4.8 Kw, 16.4 KBTU/h .
Air conditioning and ventilation should meet with local environmental, health and safety (EHS) guidelines
and regulations. Consult your usual air conditioning or EHS specialist for advice on the appropriate
measures for your location.
For a more prescriptive approach to adequate ventilation, the ANSI/ASHRAE (American Society of
Heating, Refrigerating and Air-Conditioning Engineers) 62.1-2007 Ventilation for Acceptable Indoor Air
Quality could be referred to. As an example, a minimum exhaust rate of 0.50 cfm/ft2 (2.5 L/s.m2) of
fresh make up air for "copy, printing rooms" is recommended.
NOTE: The ventilation and air conditioning units should not blow air directly onto the printer.
