Symptom
The image density is not uniform across image areas when printing onto paper that is not smooth in a high-temperature high-humidity environment. (See the example below)
Cause
When using paper that has a rough surface, the strength of the electrical field between the ITB and the indents in the paper weakens, causing low image density only in these areas.
Action
MP C6503/C8003:
Increase toner density with the following SPs.
- Change the process control target (Ideal setting: +0.03 to 1.0 from the default)
SP: 3-620-111 to 114 (Plain : Maximum M/ A : K, C, M, Y) - Execute manual process control.
SP: 3-011-002 (Manual ProCon :Exe: Density Adjustment)
Pro C5200S/C5210S:
Increase the value of Toner Adhesion using the IMSS settings.
No. | IMSS setting |
|---|---|
011 | Maximum Image Density: K |
012 | Maximum Image Density: C |
013 | Maximum Image Density: M |
014 | Maximum Image Density: Y |
