1. Improper installation height
A. Confirm that the Finisher is installed horizontally (the height of its front side and that of its rear side are the
same).
- Note that the height should be different between the cases when the Finisher
is installed in e-STUDIO281c/351c/451c and when installed in e-
STUDIO352/452 or e-STUDIO2500c/3500c/3510c.
