    Chapter 2 2.1 Basic Operation 2.1.1 Basic Operation 0009-2508 The finisher is designed to deliver copies arriving from its host machine, and its modes of delivery include simple stacking, job offset, and staple. All operations involved in these modes are controlled by the finisher controller PCB, according to the appropriate commands from the host machine.

  • Page 20: Overview Of The Electrical Circuitry

    Chapter 2 　 2.1.2 Overview of the Electrical Circuitry 0009-2509 The finisher's sequence of operation is controlled by the finisher controller PCB. The finisher controller PCB is a 16-bit microprocessor (CPU), and is used for communication with the host machine (serial) in addition to controlling the finisher's sequence of operations. The finisher controller PCB responds to the various commands coming from the host machine through a serial communications line to drive solenoids, motors, and other loads.

  • Page 21: Feed Drive System

    Chapter 2 2.2 Feed Drive System 2.2.1 Overview 0009-2510 This product consists of the Finisher unit and the Saddle Stitcher unit. The Finisher unit simply stacks sheets delivered from a host machine, offsets a stack job, or staples and delivers the sheets to the trays according to commands delivered from a host machine.

  • Page 22: Constraction Of The Control System

    Chapter 2 　 2.2.2 Constraction of the Control System 0009-2511 The copy sent from the host machine is delivered to the ejection tray, escape tray, or processing tray according to the ejection type. Job offset or stapling is performed, according to the instruction from the host machine, for copy delivered to the staple tray. When ejecting from the processing tray, rear end assist guide is used in addition to the stack ejection roller to eject the stack.

Feed two sheets of paper to buffer (two or three sheets if 2-point stapling). Then they are aligned and stapled in the processing tray and ejected.
  • Page 28 Chapter 2 　 3) The first delivery roller descends and works together with the stack delivery roller to deliver the 1st and 2nd paper toward the processing tray. At the same time, the stack in the processing tray is delivered toward the delivery tray by the return roller and rear end assist guide.
  • Page 29 Chapter 2 5) The 1st and 2nd paper delivered to the processing tray are aligned and then delivered to the delivery tray. Stack ejection roller Return roller Rear end assist guide F-2-13 <Escape Ejection (Destination: Escape Tray)> When the escape tray is specified as the destination of paper ejection in the non-sort mode, the paper delivered from the host machine to the finisher is rerouted to the path shown below by the escape inlet flapper and ejected to the escape tray.

    Chapter 2 　 2.3.4 Rear End Assist Operation 0009-2516 In order to improve stacking performance when ejecting copies delivered to the processing tray, a rear end assist guide is used in addition to the stack ejection roller to support the rear end of the stack during stack ejection.

  • Page 35: Stack Delivery Operation

    Chapter 2 2.3.5 Stack Delivery Operation 0009-2517 The stack is ejected each time three large size sheets*1 or five small size sheets*2 are offset on the processing tray. The swing motor turns and the swing guide descends. This causes the upper/lower stack delivery rollers to hold the stack.
