When letter folding is applied, the edge of the inner flap may become bent.

Solution:

The solution depends on whether letter folding is applied to multiple sheets or a single sheet.

When letter folding is applied to multiple sheets

  1. Load the paper the other side up.

  2. Print the image. Is the problem resolved?

    Yes

    Finished!

    No

    Go to the next step.

  3. On the machine operation panel: [User Tools] > System Settings > General Features > Set Letter Fold-in Position for multiple sheets to "4.0 mm". (SP 6-755-101 to 110: FM4 3rds 1 Flap:Fine Adj 1st (size) SEF (Multi Sheet))

  4. Print the image. Is the problem resolved?

    Yes

    Finished!

    Consult the product specialist.

When letter folding is applied to a single sheet

  • This procedure is applied especially to coated paper.
  • To adjust the following settings, pre-register the type of paper in use as a custom paper. For details see “3. Custom Paper Settings for Administrator” in the TCRU “Adjustment Item Menu Guide”.

  1. In General Features in System Settings, set Letter Fold-in Position for a single sheet to "7 mm".
  2. In Advanced Settings for the custom paper in use, select Letter Fold-in Posn 1: Single-sheet Fold. (SP 6-755-001 to 100: FM4 3rds 1 Flap:Fine Adj 1st Custom Paper 001 to 100)
  3. Increase the value by 0.2 mm.

  4. Print the image. Is the problem resolved?

    Yes

    Finished!

    No

    Repeat Step 2 to 4. If the problem persists even though the setting value is 4 mm larger than the maximum value, consult the product specialist.
