(See page 2-4-3), the problem may be the damaged
developer roller (in the developer unit). Replace the
developer unit (See page 1-5-27).
If the defects occur at regular intervals of 94 mm/3
(See page 2-4-3), the problem may be the damaged

Paper with rugged surface or dump tends to cause
dropouts. Replace paper with the one that satisfies the
paper specifications.
The transfer roller must be supported by the bushes at
the both ends. Clean the bush to remove oil and debris.

30).
