(4) Black dots
Note the spacing of the defects. Use the Repetitive defects gauge (See page 6-28).
• If the defects occur at regular intervals of 94 mm, the problem may be the damaged drum (in the
process unit). Replace the process unit.
• If the defects occur at random intervals, the toner may be leaking from the process unit. Replace
the process unit.
(5) Black horizontal streaks
Check the process unit’s ground of the process unit.
• The drum axle in the process unit and its counter part, the grounding tab in the printer, must be in
a good contact. If necessary, apply a small amount of electro-conductive grease onto the tab.
The drum may be defective.
• Replace the process unit.
