Solution:
1.
To identify the affected color, print three full-page, solid-fill A3 or DLT sheets for each of
cyan, magenta, black, and green, and three full-page, halftone A3 or DLT sheets for each
of cyan, magenta, and yellow.
Because it is difficult to identify white spots on yellow, green is used instead of yellow.
2.
Detach the photoconductor unit of the affected color and check the drum surface. Is the
surface stained?
Yes
Wipe the photoconductor unit surface with a clean dry cloth to remove the stain.
In the [Machine: Maintenance] group on the [Adjustment Settings for Operators]
menu, execute 0504: [Execute Cleaning Initial Setting for PCU].
No
Replace the photoconductor unit.
3.
Print the image. Has the problem been resolved?
Yes
Finished!
No
Replace the PCU cleaning unit and photoconductor unit.
4.
If the problem persists, contact your service representative.
• For details about replacing the PCU cleaning unit and photoconductor unit, see Replacement
Guide.
