Field Measure:Please replace the drum unit* when the phenomenon described below arises.*Since most drum unit replacements were caused by another problem, the old drum unit will be continuouslysupplied. Please order the new drum unit only if this phenomenon was recognized.

TopicPaper might sag between the middle roller and registration roller during paper conveying and the sagging part is
released when paper trailing edge passes through the middle roller. Therefore, the paper trailing edge might flip
up and hit the bottom of the process unit. When some impact is applied at this time, the image formed between
the developer roller and drum might be distorted and horizontal streaks might appear at 105 mm from the paper
trailing edge. Therefore, the following change was made. (Note 1)
(Note 1) This phenomenon may be outstanding when printing graphic images.
(No problem is expected when printing texts.)
Content of Changes The sponge with Mylar sheet affixed at the bottom of the process unit where the paper trailing edge hits was
thickened by 3 mm in order to narrow the paper conveying path. Accordingly, paper trailing edge vertically
sagging when it passes through the middle roller nip is now regulated and the impact at that time will be
decreased.

[Occurrence mechanism of the horizontal streaks]
1) Paper sags between the middle roller and the registration
roller due to the surface speed difference among the
rollers around the image process section.
2) When paper trailing edge passes through the middle
roller nip, the sagging part is released and the paper
trailing edge flaps vertically.
3) When the paper trailing edge hits the Mylar sheet with
sponge at the image process section due to flapping in
2), the image formed between the developer roller and
drum (at 105 mm from the paper trailing edge) is
distorted and the horizontal streaks appear.
