Before You Begin

  • The base fences can be replaced separately or together.

  • Only replacement of the front fence is described here. The replacement procedure for the rear base fence is the same.

Preparation

  1. Pull out the stack/staple unit with handle Rb12.

  2. Remove entrance guide plate [A]

  3. Now you can access the front and rear of the base fence.

    • [A] is the front of the base fence.

    • [B] is the rear of the base fence.

  4. Remove the screw (x1).

    • This screw is extremely tight, so to prevent damaging the head of the screw use a socket wrench or hex driver to remove it.

  5. Look at the lower right corner of the staple unit.

  6. Remove the screws, and then carefully remove the front of the base fence [A] (x3).

    • Work carefully to prevent pressure springs [B] from flying off.

  7. The new base fence is embossed with groups of lines [1], [2], [3].

    • The interval between the lines [1], [2], [3] is 0.5 mm [A].

  8. Attach the new front base fence (x4).

    • Pay attention to the use and order of screw attachment.
    • Screw [A] is attached last.
    • Screws [B] and [C] are used to adjust the position of the base fence.
    • Leave screw [D] loose.

  9. Set the front end of the fence bracket [A] so that it is parallel with the embossed lines [1], [2], [3], adjust the position with screws [B], and then tighten screw [C].
  10. Make sure that the space [A] is within 5.4±1 mm. If the space [A] is not within 5.4±1 mm, loosen the screw [C] and adjust the position of the fence bracket so that the space [A] becomes within 5.4±1 mm. Then fasten the screw [C].

  • When adjusting the position of the fence bracket, make sure that the front end of the fence bracket is not at an angle to the embossed lines.
