The side effects c), d), and e) occur when the toner on the ITB is wiped off. This happens
when feeding very stiff paper that pushes the mylar upwards against the ITB or when the
paper contacts the ITB immediately after the trailing edge passes the guide plate.

Special Guide Plate D0743810
To prevent these side effects, the special guide plate D0743810 was added with a PET
mylar (indicated in orange) as shown below to absorb the shock when stiff paper contacts
the mylar.
The special guide plate is also fixed to a position that maintains an acuter angle between
the paper and the ITB, which contributes to securing an even contact surface area
throughout the entire page.
IMPORTANT
Side Effect of the Special Guide Plate
Note that "scattered line images" are more likely
Air current in the gap
flicks the toner on the ITB
to occur with the special guide plate when in use
with coated paper. Due to the smaller gap
between the paper and the ITB in comparison to
the original guide plate, air in the gap is left with
no escape route and is pressurized. Toner on the
ITB is flicked by this air current, which is
enhanced by the smooth surface of coated paper.
