Model
FS-C8020MFP, FS-C8025MFP
Topic
When the drum ghost image appears, please adjust the values in the maintenance mode U101 (1st TC Output) in
order to reduce the level. However, it is difficult to completely resolve this problem. So, please adjust it while
checking the customer’s tolerable level and the balance between density and color tone.
[Maintenance mode U101 (1st TC Output) adjustment procedures]
1. Download the drum ghost image check image file “color.capt” and save it in a USB memory.
(Save in the folder down to the third level.)
*Kyocera Mita sales companies can download the image file “color.capt” at the download center on the ESDC.net.

8. Execute the color calibration whenever executing the maintenance mode U101 from “System Menu” –>
“Adjust/Maintenance” –> “Calibration”.
9. Repeat the procedures 1 through 6 until the drum ghost level and the density/color tone balance is optimized.
Caution
1. Adjust the value for each color while checking the drum ghost image level in 4 decrements for the
FS-C8020MFP and in 5 decrements for the FS-C8025MFP
2. The density and the color tone gradually change if the value for each color is lowered. Adjust it while checking
the customer’s tolerance level and the balance between density and color tone.
3. Finally, check it by using the image which the customer provided as error example.
4. This error is difficult to completely resolve even after the adjustment described above was performed. Therefore,
adjust it while checking the customer’s tolerance level and the balance between the density and color tone.
