The skew adjustment of this machine should be performed manually. The adjustment procedure is as follows:

  1. Open the front door [A] and then remove the paper exit tray [B]. ( x 1)
  2. Close the front door and execute MUSIC (SP2-111-004).
  3. Check the result for each color with the following SPs.
    • SP2-117-004 (K)
    • SP2-117-002 (C)
    • SP2-117-001 (M)
    • SP2-117-003 (Y)

    • If all of the SP values are within ±5, go to Step 5.
    • If any of the SP values are not within ±5, go to Step 4.

  4. Rotate the knob(s) shown in the diagram [A] to [D] at 90 degree intervals until the SP value for the affected color(s) is within ±5 (target: 0).

    • There are two knobs on each of the two LD units. A click is felt every 90 degree rotation.
    • Turning the knob clockwise by 90 degrees changes the SP value by -1.
    • Turning the knob counter-clockwise by 90 degrees changes the SP value by +1.
    • Example:
      SP value for magenta in Step 4 was “+6” Turn knob [C] 6 clicks (1 1/2 rotations) clockwise.
    • SP value for yellow in Step 4 was “-7” Turn knob [D] 7 clicks (1 3/4 rotations) counter-clockwise.

  5. Reattach all parts that you removed in the above steps.

    • Do not touch the LD units while installing the Paper Exit Tray. Otherwise, the LD unit may move, and you may have to adjust the color skew again.
