J033 / J034 / J083 (Paper Jam at the Fusing Unit during Solid-Fill Image Printing)

Cause:

If a solid fill image is printed, the paper may stick to the fusing belt when the paper is separated at the fusing nip exit. This causes the paper to come into contact with the separation plate and is caught in the fusing belt, resulting in a paper jam.

  1. Center of paper is caught in the belt.

  2. Separation plate

  3. The pressure roller separation plate is in contact with the paper.

  4. Fusing exit jam sensor

  5. Paper

Note

  • The jam code varies depending on the position of the leading edge of the paper.

    • J033: A paper jam has occurred before the leading edge of the paper reached the fusing exit sensor.

    • J034 / J083: A paper jam has occurred after the leading edge of the paper passed the fusing exit sensor.

Occurrence conditions:

  • Solid-fill and other images with a large amount of toner adhesion on the paper

  • High temperature environments (due to weakening of paper stiffness)

Solution:

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

2Make sure there is room to reduce the line speed and that reduced throughput will not cause any problems.

Yes

Go to the next step.

No

Proceed to "Decrease the fusing heating roller temperature".

3In [Detailed settings] for custom paper, select 1231: [Print Speed] and reduce the print speed by one step according to the color mode you wish to use.

  • 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

For example, if the print speed is [High], lower it to [Middle], and if it is [Middle], lower it to [Low].

If you change the print speed to [Middle], go to the next step.

If you change it to [Low], go to Step 5.

Print the image. Has the problem been resolved? (10 or more sheets of A4 paper)

Yes

Go to the next step.

No

Set [Print Speed] to [Low] according to Step 3, and then go to the next step.

5Is the toner fusibility within the permissible range?

Note

  • The required level of fusibility is as follows.

    • The printed image does not come off.

    • The toner does not come off even if it is lightly rubbed by a nail.

    • The toner does not come off even if it is rubbed by the cloth for cleaning the contact glass.
