• When you use paper in high humidity under hot conditions, take out only the
necessary amount of paper from the bag. Do not take all the paper out of the
bag.
Anti-humidity Heater
• When humidity is high, the paper in the paper roll tray may absorb moisture,
which can effect the image quality of your copies. The anti-humidity heater
prevents this. Set this switch to "On" when the humidity reaches more than
45%.
