Medaka (White Spots)
White dots or short lines appear, spaced at intervals of 189 mm (7.5 inches) in the direction of the
paper feed.
Cause:
The photoconductor unit is stained.
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.
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.
