Toner Blasting (Trailing Edge)

Toner blasting occurs at a part of a line or character in an area between 8 and 13 mm (0.3 and 0.5 inches) from the trailing edge of the paper and the area approximately 20 mm (0.8 inches) from the left edge.

illustration of Toner Scattering: Trailing Edge

Cause:

During paper transfer, jitter is produced when the trailing edge of paper passes the paper feed guide, resulting in blasting of part of the toner forming characters or lines.

Solution:

(a) Adjusting the image transfer output

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

2In [Detailed settings] for custom paper, Select 1212: [Image Transfer Output], and then check if the value for the intermediate (image) transfer output for the mode you use is set to "+10" (upper limit).

  • 1212-01: Image Transfer Output: BW: Black

  • 1212-02: Image Transfer Output: FC/FCS: Black

  • 1212-03: Image Transfer Output: FC/FCS: Cyan

  • 1212-04: Image Transfer Output: FC/FCS: Magenta

  • 1212-05: Image Transfer Output: FC/FCS: Yellow

  • 1212-06: Image Transfer Output: FC/FCS: Clear/Special

  • 1212-07: Image Transfer Output: FC/FCS: White

  • 1212-08: Image Transfer Output: FC/FCS: Metallic

  • 1212-10: Image Transfer Output: S: Clear/Special

  • 1212-11: Image Transfer Output: S: White

  • 1212-12: Image Transfer Output: S: Metallic

Yes

If already set to the upper limit, there is no other solution.

No

Go to the next step.

3Increase the value by one step.

4Print the image. Has the problem been resolved?

Yes

Finished!

No

Start over from Step 3.

(b) Adjusting the printing speed

1In [Detailed settings] for the custom paper you are using, select 1231: [Print Speed], and then set the value in the following corresponding settings to [Low].

Productivity Priority

  • 1231-01: Print Speed: BW/FC/FCS: BW/FC/FCS

  • 1231-02: Print Speed: FCS: Clear/Special

  • 1231-03: Print Speed: FCS: White

  • 1231-04: Print Speed: FCS: Metallic

  • 1231-06: Print Speed: S: Clear/Special

  • 1231-07: Print Speed: S: White

  • 1231-08: Print Speed: S: Metallic

High Quality

  • 1231-10: Print Speed: BW/FC/FCS: Fuser Setting HQ: BW/FC/FCS

  • 1231-11: Print Speed: FCS: Fuser Setting HQ: Clear/Special

  • 1231-12: Print Speed: FCS: Fuser Setting HQ: White

  • 1231-13: Print Speed: FCS: Fuser Setting HQ: Metallic

  • 1231-15: Print Speed: S: Fuser Setting HQ: Clear/Special

  • 1231-16: Print Speed: S: Fuser Setting HQ: White

  • 1231-17: Print Speed: S: Fuser Setting HQ: Metallic

Note

  • Reducing the print speed reduces the jitter produced when the trailing edge of the paper passes.

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

(c) Changing the paper direction

1Change the paper from that in the cross-grain direction to that in the grain direction.
