：Full-speed
*1:The fan intermittently operates every second.
*2: When the width of the last paper is narrower than the A4 size (297 mm), the fans operate
when the difference in temperature between sub thermistors TH1 and TH2 becomes 20
degree or less. When the width of the last paper is wider than the A4 size (297 mm), the
fans operate for 10 seconds after completion of printing.
*3: The fan operates at 1/2 speed only when the machine enters the standby mode after
running for more than 8 minutes for fixing.
● Paper edge cooling fan (rear)/(front) control
Purpose
These fans are used to prevent the sections where paper is not fed from heating excessively
when narrow paper (narrower than the A4 size (297 mm)) is fed.
They cool the paper passed through the fixing unit, preventing it from sticking to the
surrounding parts during delivery.
