Toner falls onto the edge of the image from the image transfer belt.

Cause:

Toner falls from the ITB cleaning unit onto the paper near the edge of the image. Normally, this problem does not appear, but can occur if the cleaning blade or other component in the cleaning unit is defective and allows toner to fall at the image starting point on the paper. Even if the toner does not fall directly onto the paper but into the paper transport path, the toner can be transferred to the paper passing below the ITB.
