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 2-2 Printer environmental specifications Relative humidity range for best print quality Relative humidity range for printing Temperature range for best print quality Temperature range for printing Temperature range when not in operation Temperature gradient Maximum altitude when printing 40-60%, depending on substrate type 20-80%, depending on substrate type 20 to 25°C (68 to 77°F), depending on substrate type 15 to 30°C (59 to 86°F) -25 to +55°C (-13 to +131°F) no more than 10°C/h (18°F/h) 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 ambient comfort levels, air conditioning or ventilation in the work area should take into account that the printer produces heat. Typically, the printer's power dissipation is 2.2 kW (7.5 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, you could refer to the ANSI/ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) 62.1-2007 Ventilation for Acceptable Indoor Air Quality. As an example, a minimum exhaust rate of 2.5 L/s.m² (0.5 cfm/ft²) of fresh make up air for "copy, printing rooms" is specified. Special ventilation equipment (air filtration) is not required to meet U.S. OSHA requirements on occupational exposure to VOCs from water-based HP Latex Inks. Special ventilation equipment installation is at the discretion of the Customer. Customers should consult state and local requirements and regulations. NOTE: The ventilation and air conditioning units should not blow air directly onto the printer. NOTE: Maintaining positive air pressure in the print production room will help prevent dust from entering the room. 4 Chapter 2 Site preparation requirements ENWW
