Environmental specifications These environmental specifications must be met to ensure that the printer operates properly. Consider the following points before installing the printer: ● Install the printer in a well-ventilated, dust-free area. ● Install the printer on a level, flat surface that can support its size and weight. Do not install on carpet or on other soft surfaces. Make sure that all four printer feet are level. ● Install the printer where temperature and humidity are stable, with no abrupt changes (away from water sources, humidifiers, air conditioners, refrigerators, or other major appliances). ● Install the printer away from direct sunlight, areas that experience vibration, open flames, ammonia fumes, ultrasonic heaters, and devices that emit a magnetic field. If the printer is placed near a window, make sure that the window has a curtain or blind to block direct sunlight. ● Maintain enough space around the printer for proper access and ventilation.
