11.2 DRIVE MECHANISM
The relay rollers are driven by the main chain [A]. The transport gate, junction
gate and inverter gate are opened and closed by solenoids [B][C].
The inverter gate solenoid [B] also switches the direction of roller rotation.
The inverter roller drive gear is engaged with the “in” gear [D] in feed-in
operation and the out gear [E] in feed-out operation.
The inverter sensor [F] detects the trailing edge of the paper to change the
direction of roller rotation. The inverter relay sensor [G] detects the paper
feed timing. Both also are responsible for misfeed detection.
