  • Page 599 PAPER SHIFT MECHANISM 4.8 PAPER SHIFT MECHANISM B408D110.WMF In the sort/stack mode, the shift roller [A] moves from side to side to separate the sets of copies. The horizontal position of the shift roller is controlled by the shift motor [B] and the shift gear disk [C].
  • Page 600 JOGGER UNIT PAPER POSITIONING MECHANISM 4.9 JOGGER UNIT PAPER POSITIONING MECHANISM B408D113.WMF B408D114.WMF In staple mode, each sheet of copy paper is vertically and horizontally aligned when it arrives in the jogger unit. For the vertical paper alignment, the positioning roller solenoid [A] turns on shortly after the stapler tray entrance sensor [B] turns off, and the positioning roller [C] pushes the copy against the bottom of the stack stopper [D].
  • Page 601 EXIT GUIDE PLATE 4.10 EXIT GUIDE PLATE [B] [C] B408D111.WMF When stacking a large size of paper (such as A3, DLT) in the jogger unit, the leading edge of the paper reaches the exit rollers. To prevent the paper from running into the exit rollers and not being aligned correctly, the exit guide plate [A] is moved up to make a gap between the exit rollers.
  • Page 602 STAPLER MECHANISM 4.11 STAPLER MECHANISM B408D116.WMF The staple hammer motor [A] drives the staple hammer. The staple sheet sensor [B] detects the leading edge of the staple sheet at the stapling position to prevent the hammer from operating if there are no staples at the stapling position.
  • Page 603 STAPLER UNIT MOVEMENT MECHANISM 4.12 STAPLER UNIT MOVEMENT MECHANISM B408D117.WMF The stapler motor moves the stapler [A] from side to side.

    TRAY SHIFTING Tray 2 (Lower Tray) B352D105.WMF In sort/stack mode, tray 2 [A] moves from side to side to separate the sets of prints. The shift mechanism for tray 2 is similar to that used for tray 1. However, when the tray 2 shift motor [B] turns on, the arm [D] moves the entire end fence [C] from side to side (not just the tray).

  • Page 631: Introduction

    TRAY UP/DOWN MECHANISMS 4.5 TRAY UP/DOWN MECHANISMS 4.5.1 TRAY 1 B352D204.WMF Introduction The tray 1 lift motor [A] controls the vertical position of tray 1 [B] through gears and timing belts [C]. Normal and sort/stack modes When the main switch is turned on, the tray is initialized at the upper position. To do this, the tray is moved up until upper stack height sensor 1 [D] is de-actuated.

  • Page 632: Staple Mode

    TRAY UP/DOWN MECHANISMS Staple mode B352D204.WMF In staple mode, stapled stacks can be delivered to either tray, but they can only go to the lower exit. So, if tray 1 is selected, tray 1 [A] moves down to the lower paper exit.

  • Page 633: Tray 1 Release Mechanism

    TRAY UP/DOWN MECHANISMS Tray 1 release mechanism When tray 1 is selected for staple mode, tray 1 must be moved down to the lower paper exit. However, to move past the sensors at the lower exit, the tray must be moved away from the finisher.
  • Page 634 TRAY UP/DOWN MECHANISMS When tray 1 is at the lower exit, the tray lock solenoid [F] is on, and the lever [G] locks the tray. This prevents the user from moving the tray out of position (the first tray has some play when it is at the lower position).

    TRAY UP/DOWN MECHANISMS 4.5.3 PRE-STACK MECHANISM 00MTY.WMF This feature is available only when using A4 L, LT L, and B5 L. During stapling, the main machine must wait. This mechanism reduces the wait by holding the first two sheets of a job while the previous job is still being stapled. It only works during the second and subsequent sets of a multi-set print job.

Stapler Rotation After the start key is pressed, the stapler rotation motor [A] rotates the staple unit [B] until the stapler rotation HP sensor [C] is activated.

  • Page 639: Stapler

    STAPLER MECHANISM 4.7.2 STAPLER B352D208.WMF The staple hammer is driven by the stapler hammer motor [A] inside the stapler. As soon as the paper stack is aligned, the staple hammer motor starts. When stapling is finished, the staple hammer HP sensor [B] is turned on, and the staple hammer motor then stops.

(The data goes to the FACE at the same time, and is checked for error lines/frames.) The FCU then decompresses the data and transfers it to page memory. If image rotation will be done, the image is rotated in the page memory.

    FAX COMMUNICATION FEATURES 4.4 FAX COMMUNICATION FEATURES 4.4.1 PERSONAL/INFORMATION/TRANSFER BOXES When an incoming message has a SUB or SEP code attached, the machine will look for a Personal Box, Transfer Box or Information Box with an identical SUB or SEP code. If a matching code is found, the message will be stored in the box and not printed, or it will be forwarded to the receiver if registered.
  • Page 839 FAX COMMUNICATION FEATURES Transfer Box The user can create transfer boxes in the machine’s memory for forwarding incoming fax messages. Each box must have a name and a code. Each box must also have destinations associated with it; any message arriving in this box will automatically be sent on to these destinations.
  • Page 840 FAX COMMUNICATION FEATURES Information Box (Polling Tx) The user can set up documents in memory to be picked up by another machine. The user makes an information box for each document. The information box is identified by a code. Anybody who wishes to call the fax machine and receive the document from the information box has to input this code as the SEP code when calling the machine.
