Turning On/Off the Power
There are two switches for the anti-humidity heaters on the internal cover which is revealed when the
Tray 1 is pulled out. Turn these switches on if the humidity level becomes high and image quality is
affected. Turn the switches off at other times.
The left switch is for the paper tray heater and the right switch is for the transfer unit heater.
