1. Turn ON the main power.
  2. Set SP4-688-002 (Scan Image Density Adjustment 1-pass DF) to "101".
  3. Execute SP4-730-002 (FROM Main Factory Setting Execution ON/OFF).
  4. Check the vertical registration for the SPDF.
    1. Create an original as shown in the following picture.
      The large white arrow indicates the direction of feed.
    2. Copy the original and make sure that the position of the line [A] is within 0±1mm

    3. If not within the standard, adjust with the SP modes.
      SP6-006-001 (ADF Adjustment Side-to-Side Regist: Front)
      SP6-006-002 (ADF Adjustment Side-to-Side Regist: Rear)

      • The above SPs must be executed with the ADF cover closed, because the SPs will not succeed if the ADF cover is opened or lifted up.

  5. Check the horizontal registration for the SPDF.
    1. Copy the original and make sure that the position of the line [B] that you wrote on the original (see above) is within 0±2mm.
    2. If not within the standard, adjust with the SP modes.
      SP6-006-010 (ADF Adjustment L-Edge Regist (1-Pass): Front)
      SP6-006-011 (ADF Adjustment L-Edge Regist (1-Pass): Rear)
  6. Check the skew.
    1. Make sure that the difference between both end positions of the line [A] that you wrote on the original (see above) is within 0±2mm.
    2. If not within the standard, change the position of the fixing screw [A] to the long hole [B] at the right hinge.
