Fusing roller/Lw cooling control

• When the temperature of the fusing roller /Lw [2] detected by the temperature sensor /2 (TEMS/2) rises
higher than a specified temperature, and the difference between the detected and the specified tempera-
tures exceeds a predetermined level, the fusing fan /Lw (M65) [4] turns on and cools down the fusing roller
/Lw.
• While the M65 is operating, the fusing heater lamp /4 is kept off.
• The fusing fan /Lw (M65) takes in air from the front side, through the duct [3] to cool the fusing roller /Lw.
• Air that passed through the fusing roller /Lw is exhausted to the rear side through the duct [1].
