Paper Jams Occur with Crumpling of the Leading Edge When Thin Paper Is Used

Paper jams occur due to insufficient separation of thin paper.

  1. Leading edge margin

  2. Trailing edge margin

Cause:

  • Due to a lack of the leading edge margin, the paper gets caught by the fusing separation plate on the fuser roller side, causing a paper jam with crumpling of the leading edge.

  • When duplex printing, the margin at the trailing edge of the paper on the front (Side 1) is lacking, causing the paper to get caught by the fusing separation plate on the pressurized side, causing a paper jam with crumpling of the leading edge.

Occurrence conditions:

  • When thin paper is used

  • When coated paper is used

  • Much toner is applied to the leading edge of the paper for a solid-fill image, etc.

  • The leading edge of the paper has some areas with insufficient margins.

  • When duplex printing too much toner is applied to the trailing edge of the paper on the front (Side 1) for a solid-fill image, etc.

  • When duplex printing is performed, the trailing edge of the paper on the front (Side 1) has some areas with insufficient margins (larger magnification).

Solution:

(a) If the width of the margin at the leading/trailing edge can be widened

1If the paper is not registered as custom paper, register the brand of the paper.

2In [Detailed settings] for custom paper, select 1239: [Margin] and increase the margin width by + 0.5 mm.

  • 1239-01: Margin: BW/FC/FCS/S: Leading Edge

  • 1239-02: Margin: BW/FC/FCS/S: Trailing Edge

  • 1239-03: Margin: FCS: Leading Edge: Clear/Special

  • 1239-04: Margin: FCS: Leading Edge: White

  • 1239-05: Margin: FCS: Leading Edge: Metallic

  • 1239-07: Margin: FCS: Trailing Edge: Clear/Special

  • 1239-08: Margin: FCS: Trailing Edge: White

  • 1239-09: Margin: FCS: Trailing Edge: Metallic

3Print the image and check if the paper jam has been resolved.

Yes

Finished!

No

Repeat Step 1 to 2.

If the problem persists even after reaching the upper limit, there is no other solution, so consider changing the paper.

Note

  • Select "Clear/Special" when using Neon Yellow, Neon Pink, or Invisible Red. Select "Metallic" when using Gold or Silver.

(b) If the width of the margin at the leading/trailing edge cannot be widened

1Check if it is possible to change the image position.

Yes

Go to the next step.

No

There is no other solution, so consider changing the paper.

2If the paper is not registered as custom paper, register the brand of the paper.

3In [Detailed settings] for custom paper, select 1239: [Margin] and increase the margin width by + 0.5 mm.

4Print the image and check if the paper jam has been resolved.

Yes

Finished!

No

Repeat Step 3 to 4.

If the problem persists even after reaching the upper limit, there is no other solution, so consider changing the paper.
