Table 2-3 Environmental specifications (continued) Temperature gradient Maximum altitude when printing 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 Eco-Carton ink cartridges are moved from a cold location to a warm and humid location, water from the atmosphere can condense 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 Eco-Carton ink cartridges, to allow the condensation 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 Ensure that the room in which the system is installed meets local environmental, health, and safety (EHS) guidelines and regulations. Adequate ventilation needs to be provided to ensure that potential airborne exposure is adequately controlled according to Safety Data Sheets. Consult the Safety Data Sheets available at http://www.hp.com/go/msds to identify chemical ingredients of your ink consumables. Airborne materials can be readily identified and quantified by using established indoor air-quality testing protocols. HP performs these assessments during the development phase for all products. HP testing shows that, during printer operation, the concentrations of airborne contaminants measured in the workspace are consistently well below key occupational exposure limits. This observation is based on exposure assessments that model very active productivity at customer facilities. Customers should recognize that actual levels in their facilities are dependent on workspace variables they control such as room size, ventilation performance, and duration of equipment use. HP's assessment, based on the available scientific information, concluded that airborne materials are not expected to present a health hazard as long as you provide a minimum of 5 ACH (air changes per hour) of fresh air ventilation and a minimum room volume of 60 m³. These specifications are valid for one HP printer using a black area-fill print at 4 passes and 100% ink density, assuming 8 h printing time per day. If there is other equipment in the room or different printing conditions, the ventilation rate should be recalculated accordingly. As an alternative to the workspace benefit provided by general room ventilation, you could choose localized ventilation to provide a more comfortable working environment. See Local exhaust on page 5 for more information. Local exhaust The installation of localized exhaust for a printer enables the capture of airborne contaminants and heat near their source of generation, and subsequently allows their efficient removal from the building through contained and relatively low-volume air flow.
