Problems
Toner Spotting/Staining
Paper Is Spotted with Toner
Paper is soiled with toner spots of 0.5–1 mm (0.02–0.04 inches) in diameter.
CEZ538
Cause:
Toner fragments have slipped through the cleaning web, which cleans the pressure roller, and readhered to paper.
This may occur if:
• Printing on both sides of paper
• Printing on uncoated (especially rough-textured) paper
• Printing a single-dot halftone image
• To adjust the following settings, pre-register the type of paper in use as a custom paper. For details
about registering custom papers, see "Registering a Custom Paper", Paper Settings Reference.
15
Solution:
Increasing the temperature when using thin paper with a thickness equivalent to Paper Weight 0 or 1
may cause paper curling, resulting in paper jams at the fusing unit. Carry out steps from Step 6 when
using thin paper with a thickness equivalent to Paper Weight 0 or 1.
1. Increase the temperature by 5 °C in [Fusing Heat Roller Temperature Adj] in [Advanced
Settings] for the custom paper in use.
2. Print the image. Is the problem resolved?
Yes Finished!
No Go to the next step.
3. Increase the temperature an additional 5 °C in [Fusing Heat Roller Temperature Adj].
4. Print the image. Is the problem resolved?
Yes Finished!
No Go to the next step.
5. Have changes to the settings resulted in glossy lines or paper misfeed?
Yes Decrease the temperature by 10 °C, and then go to the next step.
No Go to the next step.
6. Set [Adjust Cleaning Web Motor Interval] to 0.01 in [Advanced Settings] for the custom
paper in use.
7. Print the image. Is the problem resolved?
Yes Finished!
No No further improvement is likely. Contact your service representative.

CZC308
Cause:
The image transfer current is transmitted to the drum, where a potential difference occurs between a
developed area and non-developed area and causes the intended image to be reproduced.
This may occur if:
• Solid filled images or bold characters are printed in black on a halftone background
• Printing is done at low temperature or humidity
• Many screening lines are used
Solution:
1. In the [Machine: Image Quality] group on the [Adjustment Settings for Skilled Operators]
menu, select [Adjust Image Density] and execute [Image Density Adjustment: Manual
Execute].
2. Print the image. Is the problem resolved?
Yes Finished!

Scratched Images and Stained Paper Edges
Scratched images or soiled paper edges appear.
3. Troubleshooting Image Quality Problems
26
CNT008
Cause:
When a relatively stiff, thick paper is delivered, the entrance guide board for the transfer unit is warped
toward the intermediate transfer belt due to the stiffness of the paper. The edge of the entrance guide
board comes into contact with the toner on the belt to cause images to be scratched and paper edges to
be soiled.
This may occur if:
• Paper with a thickness equivalent to Paper Weight 7 is used
• Paper with its grain parallel to the paper feed direction is used. For example, A3/DLT long grain
paper is delivered, A4/LT short grain paper is delivered from its long edge, or A4/LT long grain
paper is delivered from its short edge.
• Paper is stored at low temperature or humidity
Solution:
Change the direction of paper grain for paper delivery.
• When storing paper at low humidity, wrap the paper in coated paper or a plastic sheet.

Toner Scatter
Toner Scatter (1)
Toner is scattered around a solid-fill print.
CEZ545
Cause:
This may occur if printed at low temperature or humidity.
• To adjust the following settings, pre-register the type of paper in use as a custom paper. For details
about registering custom papers, see "Registering a Custom Paper", Paper Settings Reference.
Solution:
1. Check both sides of the paper for the problem. If this problem appears only on the side 2
of the paper, skip to Step 3.
2. Adjust the setting for the side 1 of the paper. In [Advanced Settings] for the custom paper
in use, increase the absolute value of the negative current by 5% in [Paper Transfer
Current Setting: Side 1].
Example: If the present current is −40 A, change it to −42 A.
3. Adjust the setting for the side 2 of the paper. In [Advanced Settings] for the custom paper
in use, increase the absolute value of the negative current by 5% in [Paper Transfer
Current Setting: Side 2].
Example: If the present current is −40 A, change it to −42 A.
4. Print the image. Is the problem resolved?
Yes Finished!
