Main motor operation check (Cooling fan motor rotation check)
When the PRINT switch is pressed, the main motor (as well as the duplex motor in the duplex model) is operated for 30 sec. If the
developing unit is installed at that time, the developing bias, the main charger, and the grid are outputted together in order to avoid
toner consumption. Since, in this case, laser discharge is required when stopping the motor, the polygon motor is rotated at the same
time. If the developing unit is not installed, the above high voltage is not outputted and only the motor is rotated.
