E. Fusing temperature control during printing.
• Fusing temperature control prevents declining of the image stability as well as reduces
curling of the paper, uneven waxing, offset, etc., according to the paper type to be used.
• Fusing temperature control can be set from "Service mode/machine/fusing temperature".
• Adjust the fusing temperature at heating side first. If the further adjustment is necessary,
adjust on the pressure side.

F. Temperature control during low power mode
• The IH coil stops to reduce the power consumption at low power mode and make tem-
perature control by lowering the fusing temperature.
• Usually the pressure roller stops at low power mode though, the roller rotates slightly
every certain period to prevent the brush roller from being distorted.
