Solution:

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

Procedure 1: Changing the fusing temperature

1Increase the temperature by 5 °C in [Fusing Temp] in [Advanced Settings].

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

Yes

Finished!

No

Increase the temperature an additional 5 °C.

3Repeat Step 2.

If the problem persists even if you increase the temperature to 180 °C, perform Procedure 2, "Image processing 1".

Procedure 2: Image processing 1

Do the following on the Command WorkStation (CWS).

1Select "Properties..." for the image.

2Click the "Color" tab.

3In "Color mode", select "Expert Settings...".

4If "CMYK/Grayscale" is set to "Colorwise OFF", change it to an appropriate image process.

5If the problem persists even after an appropriate image process is selected, carry out Procedure 3, "Image processing 2".

Procedure 3: Image processing 2

1Are the images printed in one or two colors?

Yes

Carry out Procedure 4, "Changing the process speed".

No

(three-color printing or unknown): In the printer driver setting, select toner reduction mode.

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

Yes

Finished!

No

Carry out Procedure 4, "Changing the process speed".

Procedure 4: 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.

Example when printing on A4/LT paper:

<Pro C5200S>

If the process speed is changed from [High] to [Middle]: 65 cpm 50 cpm

If the process speed is changed from [Middle] to [Low]: 50 cpm 32 cpm

<Pro C5210S>

If the process speed is changed from [High] to [Middle]: 80 cpm 55.8 cpm

If the process speed is changed from [Middle] to [Low]: 55.8 cpm 35.7 cpm

1In [Advanced Settings] for the custom paper in use, select [Process Speed Setting].

2Decrease the value by one level.

If the present value is [High], select [Middle]. If it is [Middle], select [Low].

3Print the image and check toner fusion. Is the problem resolved?

Yes

Finished!

No

If the problem persists, the machine may be faulty or the paper unsupported. Contact your service representative.
