Cause:
When transporting thick paper that is very stiff, the stiffness of the paper causes the entrance guide
board for the transfer unit to warped toward the ITB. The edge of the entrance guide board comes into
contact with the toner on the belt, thus causing the images to be scratched and the paper edges to be
soiled.
This may occur when:
 Paper with a thickness equivalent to Paper Weight 7 is used
 Paper with its grain parallel to the paper feed direction is used. For example, when A3/DLT long
grain paper is delivered, or when A4/LT short grain paper is delivered from its long edge, or when
A4/LT long grain paper is delivered from its short edge.
