11.3.6 Sequence of Fan Operation

iR105i/iR105+ / iR9070
The machine's fans may be either ones operating in conjunction with the state of the printer unit or ones operating in conjunction with the state of the
scanning lamp, as shown in figure.
The scanner cooling fan and the power supply fan operate in relation to the states of both printer unit and the scanning lamp; they are, however, controlled
to the higher speed.
When a fan error occurs or the door is opened, the state which the fan was in prior to the error will be used.
