Note

Imaging drum defects

Causes:

●Damage such as scratches or dents on the imaging drum. These usually appear as black or white marks on the page.

●Paper dust adhering to the imaging drum. These usually appear as white marks in the dark printed areas of the page.

●Exposure of portions of the imaging drum to light. This causes light sections in the printed output. The life of the imaging drum is shortened by exposure to light.

Actions:

●Print at least four configuration pages to determine if the defect repeats in the same horizontal orientation.

●Inspect the imaging drum for scratches, dents, or other damage. Replace if needed.

●If the problem is dust, remove the dust with isopropyl alcohol applied with a lint-free, static-free wipe. Try this only if the print defect is unacceptable and the only other alternative is replacing the imaging drum.

●Defects caused by exposure to light might clear up over time. If severe, replace the imaging drum.

In certain areas of California, air pollution control regulations restrict the use of liquid Isopropyl Alcohol (IPA) as a cleaning agent. In those areas of California, please disregard the previous recommendations and use a dry, lint-free cloth. The cloth may be moistened with water if desired.
