5) When a specified period of time elapses after the reverse motor rotates in reverse, the duplexing solenoid (SL5017) is turned ON.
When the duplexing/delivery flapper moves up, the feed path toward the duplexing feed assembly is secured. The paper is transported through the duplexing
feed assembly.

6) The paper is transported while being pressed to the left edge guide when it is transported by the skew roller of the duplexing feed assembly.
During this operation, the paper skew and horizontal registration of the second side is corrected.

7) When a specified period of time elapses after the pre-registration sensor (SR708) detects the lead edge of the paper, the duplexing feed motor stops.
This specified period of time varies depending on the paper length.
The paper stops at the re-pickup position.
8) The main controller sends the print command for the second side to the DC controller.
9) The DC controller drives the pickup motor (M4) at the timing when duplexing re-pickup can be performed.
The paper skew is corrected by the registration shutter, and the paper is transported to the ETB unit.
10) After the above-mentioned procedures, the machine delivers the paper to the delivery tray, following the procedure of delivery operation.
In this condition, the duplexing/delivery flapper is turned down, so the feed path toward the duplexing feed assembly is closed.
