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.
