Vertical Glossy (In-track) Streaks (Due to the Toner Wax on the Image)

Toner wax in the shape of the fuser belt smoothing roller stains the image.

illustration of Vertical Glossy Line: Uneven Glossiness due to Wax Stain

Cause:

This is caused by uneven wax adhesion on the fusing belt.

This is prone to occur when printing images covering a high image area of 40% or more in total of all colors on paper with a thickness of Paper Weight 4 or more.

Solution:

(a) Execute Smooth Fusing Belt

1In the [Machine: Maintenance] group on the [Operator Adjust.] menu, select 0508: [Manually Smooth Fusing Belt], and then execute 02: [Uneven Gloss (Short Time)].

2Print the image. Has the problem been resolved?

Yes

Go to the next step.

No

Execute 02: [Uneven Gloss (Short Time)] in 0508: [Manually Smooth Fusing Belt] until the problem is resolved.

3Check to see if reducing throughput causes any problems.

Yes

Proceed to "(b) Adjust the print speed and fusing temperature".

No

Finished!

Note

  • Improvement can be expected, and the effect is permanent. On the other hand, there is a side effect of reduced throughput.

(b) Adjust the print speed and fusing temperature

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