[ 3] Recording mode (Solenoid: OFF, Motor rotation: Forward) In the recording mode, the control electronics deactivates the solenoid. When the motor rotates in the forward direction, the clutch lever turns counterclockwise with the spring so that its cutout ® becomes engaged with the stopper of arm A. Once arm A is locked, the planet gear 20A ("L") will not be engaged with any other gear but simply idle. The motor's rotational torque turns the sun gear 20/90 ("B") counterclockwise so that the planet gear 20B ("C") transmits the torque via the gear 39 ("M") and other gears to the platen gear ("a") as well as the paper ejection roller gear ("X"). The platen advances recording paper and its paper movement rotates the paper feed roller. Consequently, the paper feed roller shaft rotates faster than the paper feed roller gear ("T"). If the platen gear ("a" in the figure below) on the left end of the platen shaft rotates, the gear 33RB ("b") on the right end also rotates so as to drive the friction torque transmission ASSY and ribbon drive gear ("e") that rotates the ribbon take-up gear ("f") in the ribbon cartridge, as shown on the next page.
