Operating Principles
2.1 OVERVIEW
This section describes the operating principles of the Duplex Unit.
2.1.1 Paper Transportation
Paper is transported through the printer Base Engine and the Duplex Unit along the paper path shown in the Figure below when the Duplex Mode is selected or the optional Face UP Catch Tray is installed and selected. In the Duplex Mode, a sheet of paper printed on one side is guided into the Duplex Unit to re-feed, turned over in the Duplex Unit, reversed, and fed again into the Base Engine. When the optional Offset Catch Tray is selected, a sheet printed on one side in the Simplex Mode or a sheet printed on both sides is delivered into the Face Up Catch Tray through the Duplex Unit.

SCANNING DIRECTION IN DUPLEX PRINTING The figure below shows the relationship between the main and sub scanning direction and a side of the page printed in duplex printing. The controller sends the image data to the engine according to the printing order of pages, lines (raster lines) on each page and pixels on each line.

Operating Principles
2.1.3 Function of Duplex Unit Major Components
VERTICAL UNIT
Generates the drive power for the Duplex Unit. Transmits the drive power from the Motor Duplex to the Roll Assembly Exit and to Roll Assembly #1 (part of the Horizontal Unit). When the Vertical Unit is in place, the Idler Gear in the Gear Cluster engages the gear on the end of the Roll Assembly #1 shaft, and transmits the drive power to Roll Assembly #1. When the Vertical Unit is tilted back, the Idler Gear disengage from the gear on the Roll Assembly #1 shaft. Works with Rolls Pinch to drive paper from the Fuser Exit Roll Assembly into the Vertical Unit. The drive power is transmitted from the Base Engine to the Roll Assembly, through the Duplex Gear Assembly of the Base Engine and the gears in the Duplex Unit. Works with Rolls Pinch to drive paper out into the Face Up Catch Tray. The drive power for the Roll Assembly Exit is transmitted from the Motor Duplex through the Gear Cluster. A moving baffle that switches the paper path to either Roll Assembly #1 or to the Roll Assembly Exit. Toggles the Gate Upper.

Sensor Assembly: Sensor in the Vertical Unit which is located near the inlet and detects paper which enters the Duplex Unit. This sensor is also called the Vertical Sensor. Pushed down by the paper coming from the Gate Upper, allowing the paper to proceed on to Roll Assembly #1. Without the weight of the paper pushing it down, the Gate returns to its raised position. Then the sheet of paper, driven in the reverse direction by Roll Assembly #1, is guided by the bottom side of the Gate Lower to Roll Assembly #2.

Operating Principles
Chute Lower:
Fan Duplex:
Expels the air inside the Duplex Unit (and the printer through the rear exit of the printer) and introduces fresh air into the Duplex Unit and the printer) to prevent an excessive rise of the inside temperature. Secures the Vertical Unit to the rear of the Base Engine.

Operating Principles
HORIZONTAL UNIT
Bracket & Gear Assembly:Receives the drive power from the Base Engine, and transmits it to Roll Assemblies #2, #3, and #4 of the Horizontal Unit. Roll Assembly #: Receives the drive power from the Motor Duplex and Gear Cluster which are part of the Vertical Unit. Roll Assembly #1 rotates forward when receiving a sheet of paper with the first side printed. Roll Assembly #1 then rotates in reverse to drive the sheet to Roll Assembly #2 in preparation for printing the second side of the sheet. Drive the paper into and out of the Duplex Unit.
Roll Assemblies#2/3/4:
PWBA Assembly Duplex: Controls the Duplex Unit operation. The 4-bit MPU on the PWBA Duplex receives commands from the PWBA MMCU, receives signals from the Sensors within the Duplex Unit, actuates the Solenoid Duplex, and the Motor Duplex, and returns the status of the Duplex Unit. Horizontal Sensor: Figure 2-7. Duplex Unit - Horizontal Unit Components Duplex Unit ChuteCover Interlock: Photo interrupter (PL11.24) that monitors whether or not the Duplex Unit Chute Cover is in place. Vertical Unit Interlock: Photo interrupter (PL11.24) that monitors whether or not the Vertical Unit is in position against the rear of the Base Engine. Detects when a sheet of paper reaches Roll Assembly #2.

4.1.1 Precautions
This section describes the precautions you must take to prevent accidents during disassembly and reassembly work. Be sure to carry out all work in accordance with the precautions and general instructions provided in this manual.
C A U T IO N
Be careful to avoid injury from frame edges and other sharp or protruding areas of the printer. Avoid touching IC elements with bare hands, so as to prevent possible damage from electrostatic discharge. If you need to touch these areas, wear appropriate electrostatic protection gear (electrostatic wrist band, etc.). To ensure work efficiency and safety, use only the tools specified in this manual. The unit uses screws of many different types. Be sure to note the correct location for each screw before removing it. Inserting screws into the wrong places may strip or damage the screw holes.
