Fig. 6-13 Example of Regular
Marking
The problem may disappear by itself. Try printing
multiple pages to clear this problem especially if the
printer has not been used for a long time.
If the surface of the drum has been scratched, replace
the drum unit with a new one.
If the problem does not disappear, it may be that the
drum has been marked or damaged due to excessive
exposure to light. In this case, replace the drum unit
with a new one.
