Do this procedure to confirm that the paper is centered in the paper path.

  1. Make sure that the I/F cable of the unit is connected to the upstream unit.
  2. Disconnect the unit to the left of the unit to be tested.
  3. Execute a run by feeding paper from Tray 2 of the host machine.

    • If you are testing the Ring Binder, execute the run by feeding paper (A4 or LT LEF) from Tray 2 of the host machine (punching only, no ring binding). (The Ring Binder cannot accept a larger paper size.) Feed A3 SEF for other units.

  4. When each sheet exits, check the position of the paper on the scale to see if the paper is centered.
    • Read the rear scale for DLT-size paper.
    • Read the front scale for A3-size paper.
    • If you are testing the ring binder, read the rear scale for LT LEF paper and the front scale for A4 LEF paper. With the Ring Binder, the paper does not exit. It will switch back and feed to the punch unit.
    • The scale lines are spaced 2 mm apart.
  5. The paper must not deviate more than ±2 mm on the scale.

    [A]

    Leading/trailing edges centered. No adjustment necessary.

    [B]

    Leading/trailing edges offset to the rear by more than 2 mm. Adjustment required.

    [C]

    Leading/trailing edges offset to the front by more than 2 mm. Adjustment required.

    If the edge of the paper is on the scale at the center [A], no adjustment is required.
    -or-
    If the edge of the paper is ±2 mm off the center line on the scale, adjustment is required. Do the procedure in the next section.
