Power transmission routes of the ASF motor and paper feed motor
The rotational torque of the ASF motor is transmitted to the ASF/maintenance drive gear which
always meshes with the clutch gear L, as described in
When the mode switching lever is in the left position (normal SF or high-speed feed mode), the
clutch gear L also meshes with the ASF changeover gear which transmits the ASF motor
rotation via a gear train to the paper pull-in rollers.
The rotational torque of the paper feed motor is transmitted via the PF roller gear L to the paper
feed roller that advances paper to the printing start position.
