SAMPLE PAGE FROM THE MANUAL:
- In duplex printing, paper ejected from the fuser unit for which printing onto the first side (front side) is complete is guided toward the lower part of the fuser unit along the duplex guide of which the direction has been changed, and fed to the separation B roller in the ejection feedshift assembly.
- The paper that reaches the separation B roller is conveyed with rotation of the separation B roller, passes between the duplex A guide and the duplex A guide plate in the duplex conveying A assembly, and then is fed toward the duplex roller in the duplex conveying B assembly.
- After the paper turns on the duplex guide sensor in the duplex conveying B assembly, the leading edge of the paper that reaches the duplex roller is ejected onto the left guide of the intermediate tray in the duplexer with rotation of the duplex roller, passes under the duplex forwarding pulley that has been raised, and is fed toward the right guide of the intermediate tray.
- After ejection progresses and specified time elapses since the trailing edge of the paper turns off the paper guide sensor, the duplex tapping solenoid is activated, the trailing edge tapping guide lowers, and the trailing edge of the paper is tapped down onto the left guide of the intermediate tray.
- At the next timing, the duplex side registration motor is activated to move the duplex side registration guide according to the paper size and positions the paper located on the left guide of the intermediate tray to the center of the paper path. After positioning, the duplex forwarding solenoid is activated and lowers the duplex forwarding pulley to ground the paper located on the left guide of the intermediate tray.
- The paper is conveyed with rotation of the duplex forwarding pulley, the trailing edge of the paper becomes the leading edge, and the paper is fed toward the switchback pulley. The paper reaches the switchback pulley after turning on the duplex conveying sensor, is conveyed with rotation of the switchback pulley, is guided toward the lower part of the duplexer along the switchback feedshift guide, turns on the duplex registration sensor, and then is fed toward the duplex registration roller.
- The paper that reaches the duplex registration roller is conveyed with rotation of the duplex registration roller and is fed to the lower duplex conveying roller. The paper that reaches the lower duplex conveying roller is conveyed with rotation of the lower duplex conveying roller and is fed toward the lower duplex conveying B roller.
- The paper that reaches the lower duplex conveying B roller is conveyed with rotation of the lower duplex conveying B roller, goes out of the duplexer, and is fed toward the ejection guide assembly. The paper is guided into the machine along the upper duplex guide and the lower duplex paper feed guide that constitute the ejection guide assembly, and the leading edge of the paper turns on the registration sensor.
- At this time, primary paper feed of the second side (reverse side) of paper (refeed) is complete.In duplex printing, paper ejected from the fuser unit for which printing onto the first side (front side) is complete is guided toward the lower part of the fuser unit along the duplex guide of which the direction has been changed, and fed to the separation B roller in the ejection feedshift assembly.

The paper that reaches the lower duplex conveying roller is conveyed with rotation of the lower duplex conveying roller and is fed toward the lower duplex conveying B roller.
- The paper that reaches the lower duplex conveying B roller is conveyed with rotation of the lower duplex conveying B roller, goes out of the duplexer, and is fed toward the ejection guide assembly.
- The paper is guided into the machine along the upper duplex guide and the lower duplex paper feed guide that constitute the ejection guide assembly, and the leading edge of the paper turns on the registration sensor.
