Temperature and Humidity Temperature and humidity, both in the print production and in the storage areas can affect the print output results. If not maintained within the recommended values, as shown below, they may have an adverse effect on the print quality and/or damage sensitive electronic devices in the system. The following factors should be considered and submitted to the airconditioning engineer to assist in designing the climate control unit: • Room construction and layout • Heat emission produced by the heat emitting elements in the production room • FB7600 printer, UV lamp and power supply • Vacuum pumps - if located within the print production area • Other heat emitting devices such as lights and other machines • Number of persons in the print production area • Air extraction from the production room by the ventilation and fume extraction hood Print Production Area Room temperature: 15 - 30°C (59 - 86°F) Relative humidity: not less than 50% Rh Note In order not to interfere with the SICK safety scanner operation, the humidifiers in the production area should be positioned not closer than 10 m away from the printer's Danger Zone (see Figure 1-5 on page 11). Caution Very low relative humidity increases the risk of damage to sensitive electronic devices caused by Electrostatic Discharges (ESD). Excessive humidity may also cause corrosion problems and moisture contamination within the equipment. 33
