    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 464: 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 465: 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 466 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 4.5.2 TRAY 2 Overflow condition Multi Tray Staple Mode Normal Mode B352D500.WMF B352D109.WMF The tray 2 lift motor [A] controls the vertical position of tray 2 [B] through gears and timing belts [C]. The paper height detection is the same as for tray 1. When the tray lowers during printing, the tray is judged to be overflowing when the tray 2 overflow sensor 1 [D] is off and the tray 2 overflow sensor-2 [F] is on (see ‘Normal Mode’...

    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.

    JOGGER UNIT PAPER POSITIONING MECHANISM 4.6 JOGGER UNIT PAPER POSITIONING MECHANISM B352D110.WMF In staple mode, each sheet of copy paper is vertically and horizontally aligned when it arrives in the stapler tray. Vertical Paper Alignment After the trailing edge of the paper passes the stapler tray entrance sensor [A], the positioning roller solenoid [B] is energized for a specified time to push the positioning roller [C] into contact with the paper.

    STAPLER MECHANISM 4.7 STAPLER MECHANISM 4.7.1 STAPLER MOVEMENT B352D112.WMF B352D113.WMF The stapler can be moved from side to side or rotated according to the requirements of the selected stapling mode. 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 471: 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.

    STAPLER MECHANISM 4.7.3 FEED OUT AND TRANSPORT B352D115.WMF B352D114.WMF When stapling starts, the exit guide plate motor [A] switches on and opens the exit guide plate [B], so that the stapled stack can exit to the tray. The exit guide plate sensor [C] detects when to switch off the exit guide plate motor.

    PUNCH UNIT (OPTIONAL) 4.8.2 PUNCH WASTE COLLECTION B352D117.WMF Waste punchouts are collected in the punch waste hopper [A] below the punch unit inside the finisher. When the top of the punchout waste in the hopper reaches and actuates the hopper sensor [B], a message will be displayed on the operation panel after the current job is completed.

DETAILED DESCRIPTIONS 2.1 PICK-UP AND SEPARATION ROLLER RELEASE MECHANISM A682500.WMF A682D501.WMF When the paper tray [A] is not inside the paper tray unit, the separation roller [B] is away from the paper feed roller [C], and the pick-up roller [D] stays in the upper position.
  • Page 485 PAPER LIFT MECHANISM 2.2 PAPER LIFT MECHANISM A682D502.WMF The paper tray switch [A] detects when the paper tray [B] is placed in the machine. When the machine detects that the paper tray is in the machine, the tray lift motor [C] rotates and the coupling gear [D] on the tray lift motor engages the pin [E] on the lift arm shaft [F].
  • Page 486 PAPER LIFT MECHANISM A682D504.WMF When the paper tray is placed in the machine, the pick-up roller [A] lowers. When the top sheet of paper reaches the proper height for paper feed, the paper pushes up the pick-up roller, and the actuator [B] on the pick-up roller supporter activates the lift sensor [C] to stop the tray lift motor.
  • Page 487 PAPER END DETECTION 2.3 PAPER END DETECTION A682D503.WMF If there is some paper in the paper tray, the paper end feeler [A] is raised by the paper stack and the paper end sensor [B] is deactivated. When the paper tray runs out of paper, the paper end feeler drops into the cutout [C] in the tray bottom plate and the paper end sensor is activated.
  • Page 488 PAPER HEIGHT DETECTION 2.4 PAPER HEIGHT DETECTION The amount of paper in the tray is Full detected by the combination of two paper height sensors, [A] and [B]. When the amount of 2 paper decreases, the bottom plate pressure lever [C] moves up and the actuator [D] which is mounted on the same drive shaft as the pressure lever rotates.
