Solution:

Carry out the following sequence of procedures. Terminate the sequence as soon as the problem is resolved.

Procedure 1: Changing the fusing temperature

1In [Advanced Settings] for the custom paper, adjust the fusing heat roller temperature.

<Printing in full color >

Select 1241: [Fusing Temperature], and then increase the value in [Heat Roller Temp] of [FC] by 5°C.

<Printing in black and white>

Select 1241: [Fusing Temperature], and then increase the value in [Heat Roller Temp] of [BW] by 5°C.

2Print the image and check toner fusion. Has the problem been resolved?

Yes

Finished!

No

Increase the temperature an additional 5 degrees.

3Repeat Step 2.

If the problem persists even if you increase the temperature to 190 degrees, perform "Procedure 2: Changing the process speed".

Procedure 2: Changing the process speed

This will slow down the printing to give the toner more time to fuse. However, because of this, throughput will be reduced.

For details about "Process Speed Setting", see "Details of Menu Items in Advanced Settings", Adjustment Item Menu Guide.

1In [Advanced Settings] for the custom paper, set [Process Speed Setting] in 1331: [Motor Speed] to [Low Speed].

2Print the image and check toner fusion. Has the problem been resolved?

Yes

Finished!

No

Note

  • Changing the fusing temperature or changing the process speed may produce one or more of the following side effects:

    • Paper curling

    • Paper misfeeding

    • Blister-like white spots

    • Glossy lines

    • Change of gloss

  • If one or more of the above side effects occurs, adjust the fusing temperature and process speed by decreasing the fusing temperature and increasing the process speed.

  • After performing the solution, it is recommended to perform the color calibration of the external controller. For details see, Operating Procedure for Color Calibration.

  • Check the toner fusibility 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 optical cleaning cloth.
