Glossy banding approximately 14 mm (0.6 inches) wide occurs at an area 33 mm (1.3 inches) from the center in the paper feed direction.

Glossy banding approximately 14 mm wide appears at an area 33 mm from the center in the paper feed direction on Side 2 in duplex printing or on the printed side when delivering the paper face down in single-side printing.

Cause:

A temperature difference occurs on the toner surface between the sides with and without contact between the transport drive roller and the image. Furthermore, the roller pressure changes the surface properties of the toner, resulting in a gloss difference.

Occurrence conditions:

  • When printing on thick paper equivalent to Paper Weight 8

  • When printing on slippery paper

  • When printing solid-fill images

Solution:

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

2Check to see if there is a margin to reduce the line speed, and if reducing throughput causes any problems.

Yes

Go to the next step.

No

Proceed to "Decreasing the Fusing Heat 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.

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.

Yes

Finished!

No

Change the print speed to "Low". Go to "Decrease the fusing heating roller temperature.".
