Toner scattering occurs for a portion of lines or letters. This may occur in a line or letters that is 8 to 13 mm (0.3” to 0.5”) from the trailing edge, and 20 mm (0.8”) or less from the left edge in the paper feed direction.
Cause
A shock occurs when the trailing edge of the paper leaves the paper transport guide during the paper transfer, and then causes toner scattering.
This is likely to occur if:
Using thick paper (paper weight 4 or heavier)
