Duplexer
The operation sequences of the Duplexer are controlled by the Duplexer Driver. A
The Duplexer Driver drives the Solenoid, Motors, and Fan according to commands sent from the Engine Controller Board to the Duplexer and Duplex Pickup command via serial communication. The Duplexer also returns its status to the Engine Controller Board.
+24VDC is supplied to the Duplexer from the printer, and +5V for the ICs is generated from the +24VDC inside the Duplexer Driver.
Reversing and Duplexer Pickup
The paper is fed to the Duplexer by the Top Output Bin Deflector. This Top Output Bin Deflector moves in conjunction with the Top Output Bin. However, the Top Output Bin Deflector is controlled by the Duplexer Solenoid (SL701) when the Top Output Bin is closed.
The feed direction of the paper in the Duplexer is controlled by the Reversing Roller. The paper is then transported by the Oblique Roller and Feed Roller so that its edge contacts with the left panel to correct its skew.
The Duplexer has two stepping motors, the Reversing Motor (M701) and the Duplex Feed Motor (M702). Normal and reverse rotations are controlled by the Duplexer Driver.
