Sequence Of Fan Operation - Canon iR105 Service Manual

CHAPTER 2 NEW FUNCTIONS

8.3 Sequence of Fan Operation

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 either F02-803-01 or F02-803-02.
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.
