Location:

Intermed. Transfer Belt Ass’y

Subject:

Measures against the displaced reflecting surface of the transfer belt

Detail:

<Symptom>
In printing or copying, the following kinds of faulty images are printed: image with the upper and lower parts
put in the other way around (P-1), image with changed color tone (P-2), and image with no margin at the leading
and trailing edges.

Ref No.:

iR6800C-034 Rev. 1
(F2-T01-0M3-10090-02)

Date:

May 2006

<Cause>
The reflecting surface [A] on the inner surface of the transfer belt is displaced, preventing the ITB home position
signal from being detected at the correct time. The degree of displacement of the reflecting surface [A] and the
type of job (i.e., the type of paper used, the number of copies specified, etc) at that time cause the symptom.
