Use this procedure or the one in the next section. The second method is faster and easier.

This check and adjustment ensures that the image areas on both the front and back sides of the paper are the same size and aligned with one another. This adjustment is done before the machine leaves the factory, and can also be done at machine installation.

To do this adjustment you will need to:

  • Set Tray 2 for normal paper, thickness 2
  • Load A3 normal paper in Tray 2
  • Print the Trim Pattern
  • Do some simple calculations, based on measurements of the Trim Patterns, and then do some adjustments
  1. Set the A3 Normal paper in Tray 2.

  2. Enter the SP mode, and then check and set the following SP codes.

    2103-001

    • Note the setting.
    • If it is not “4.0”, set it to “4.0”.
    • Restore the original setting after adjustment.

    2122-112

    • Note the setting.
    • If it is not “0”, set it to “0”.
    • Restore the original setting after adjustment.

    2103-002

    • Note the setting.
    • If it is not “4.0”, set it to “4.0”.
    • Restore the original setting after adjustment.

    2103-003

    • Note the setting.
    • If it is not “2.0”, set it to “2.0”.
    • Restore the original setting after adjustment.

    2103-004

    • Note the setting.
    • If it is not “2.0”, set it to “2.0”.
    • Restore the original setting after adjustment.

    1004-001 to 003

    • Note the settings.
    • Make sure that all these SP codes are set to their defaults.
    • Do not restore the original settings after adjustments.

    1005-001 to 004

    2102 - 041 to 044

    • Set all of these SP codes to “0”.

  3. Do SP2109-003, select pattern #14, and then print Trimming Area patterns on both sides of 5 A3 sheets.

    • The procedure for printing the pattern is different for the Printer model. For details, see the section below: “Printing Pattern #14 for the Printer Model”.

  4. On the front side [A] of each A3 sheet, record the measurements of and at the leading edge and left edge, and then calculate the average value of the 5 measurements.
  5. On the back side [B] of each A3 sheet, record the measurements of and at the leading edge and left edge, and then calculate the average value of the 5 measurements. You can fill in the table below to record the measurements and averaged results.

  6. Use the average values you calculated for ,,, above in the following calculations to determine the magnification rates.
    Front, Main Scan (%) = Ave. mm / 293 mm x100
    Front, Sub Scan (%) = Ave. mm / 412 mm x100
    Back, Main Scan (%) = Ave. mm / 293 mm x 100
    Back, Sub Scan (%) = Ave. mm / 412 mm x 100

  7. Enter the results calculated in Step 6 into SP2102-041, 042, 043, 044 (front/back, main/sub scan) to adjust magnification for both the front and rear sides of the paper (you can adjust in 0.025% steps).

  8. After entering the calculated values, print another 5 Trim Patterns (front/back sides) with SP2109-003 Pattern #14, and then do the measurements again at Step 4 and Step 5 to check the magnification rates for the front and back sides of the paper.
