Cause
This problem occurs when pressure during transfer causes toner to contract at color texts where toner deposits partially increase, or at the edge of solid images.
This is likely to occur if:
There is a large amount of toner deposit.
When using in a high temperature or high humidity environment.
When using paper with a high degree of smoothness such as glossy coat paper.
When using small size paper (the smaller the paper size, the more likely the problem is to occur).
