CHAPTER 7 EXTERNALS/AUXILIARY MECHANISMS
The scanner cooling fan (FM1) is turned on and off according to the temperature detected by
the scanner thermistor (TH2).
If the reading by the thermistor is 37.5°C or higher and the copying speed reaches 6 cpm, the
fan starts to rotate. If the reading is lower than 37.5°C, on the other hand, the fan will not rotate if
no more than one copy is made or while making the first copy of a continuous copying job. (It
rotates when making the second and subsequent copies of a continuous copying job.)
