Mottled
Cause:
The transfer electric field on the concave portion of paper is weakened to cause a decrease in
transcription.
This may occur if:
• Using paper with a rough surface
• Continuously printing an image that consumes little toner
• Printing is done at high temperature or humidity
Solution:

not exceed 100%. To check this, select 0516: [Display Parts Life Counter] of the [Main Unit:
Maintenance] group in [Adjustment Settings for Operators].
For details about checking the counter, see Adjustment Item Menu Guide.
If the [Display Parts Life Counter] has exceeded 100%, replace the corresponding part.
For details about replacing the parts, see Replacement Guide.
