The diagram shows the configuration of the control system of the fixing roller and fixing belt drive system.
Fixing motor (M38) is driven at 285 mm/sec for constant velocity print, and 95 mm/sec for 1/3 print.
At warm-up and print (in the state that the fixing roller is driven), the fixing belt is pressed by the fixing roller. In this case, the fixing belt is driven by the fixing
motor (M38). In a stand-by state (in the state that the fixing roller is stopped), the fixing belt is separated from the fixing roller. In this case, the driving source of
the fixing belt is switched to the fixing belt drive motor (M36).
The fixing belt is driven in the stand-by mode in order to control temperature. It is driven at low speed (about 30-40 mm/sec) to prevent belt displacement.
