Troubleshooting. Mottling/Uneven Transfer
Problem
Due to insufficient transfer ability, mottling/uneven transfer may occur.
Cause
This may be due to reasons such as your machine's operation condition (such as the moisture or type of paper), season, and ambient environment (HH condition/LL condition).
Solution
Set [Anti-humidity (Image Dropout Prevention)] to [Active].
User Tools > Maintenance: Print > Anti-humidity (Image Dropout Prevention)
If the problem persists, it may be possible to temporarily evade the problem by changing the paper type and paper thickness settings. The paper type settings can be specified using the machine's control panel, so provide customer guidance accordingly.
User Tools > System Settings > Tray Paper Settings > Paper Type: (tray name) > Paper Type/Paper Thickness
Reference (Transfer voltage control specifications)
Toner transferability varies according to the ratio between the areas of the paper and the transfer belt, so transfer voltage control is adjusted to stabilize image quality. Paper transfer current setting is adjusted according to the paper width.
