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.
Note
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.
