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 device.
  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.
  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.
    • 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.
