Site preparation Room and spacial requirements Temperature and humidity The temperature, humidity, and temperature gradient during operation and during storage must be kept within the standard ranges to ensure the correct operation of the printer. Failure to keep these environmental conditions within the standard ranges may cause image quality problems or damage sensitive electronic components. Table 2-8 Printer environmental specifications Temperature range Humidity range Temperature gradient Operating for optimal print quality 20 to 25°C (68 to 77°F) 40 to 60% Relative Humidity 10°C/h (50°F/h) or less Operating for standard printing 15 to 30°C (59 to 86°F) 20 to 70% Relative Humidity 10°C/h (50°F/h) or less Not operating (in transport or 5 to 55°C (41 to 131°F) storage), ink in tubes 90% Relative Humidity at 55°C (131°F) 10°C/h (50°F/h) or less Not operating (in transport or -25 to 55°C (-13 to 131°F) storage), no ink in tubes 90% Relative Humidity at 55°C (131°F) 10°C/h (50°F/h) or less Maximum operating altitude: 3000 m (10000 ft) 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. Specifically, the printer's power dissipation is 15 KW (51 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. NOTE: The ventilation and air conditioning units should not blow air directly onto the printer. NOTE: You are recommended to maintain a positive airflow in the print production room to help prevent dust from entering the room. ENWW Room and spacial requirements 11
