� During copying, held rotating at a high speed. When copying is completed, rotates at a high speed for the specified time according to the temperature in the machine, then starts rotating at a low speed. 2 OFF timing � During warm-up, stops when M2 (drum) is turned off. � After completion of warm-up, not turned off until SW2 (sub power) is turned off. b FM2 (writing section cooling) 1 ON timing Turned on when M15 (polygon) is turned on. � During copying, held rotating at a high speed in sync with M2 (drum). � When not copying, held rotating at a low speed. 2 OFF timing Not turned off until SW2 (sub power) is turned off. c FM5 (cleaner cooling) 1 ON timing Turned on when SW2 (sub power) is turned on. � During coping, held rotating at a high speed. � When copying is completed, starts rotating at a low speed after a lapse of the specified time from turning off of M7 (paper exit). After this, switching between high- and low-speed operations takes place according to the temperature in the machine. 2 OFF timing Not turned off until SW2 (sub power) is turned off. d FM6 (paper exit/F), FM7 (paper exit/R), and FM8 (main cooling/2)
