Cause 2: Drum scratches caused by insufficient lubrication
If the drum surface is not sufficiently lubricated, excess friction between the drum and
cleaning blade could cause the cleaning bade to flip (or bend) and scratch the drum.
Cause 3: Drum scratches caused by narrow PG
Another factor that causes drum scratches is a narrow PG (potential gap), in which the gap
between the development roller and drum is narrower than the specification. In this
condition, stress is applied to the developer in the development process because the
developer is forced to move through a narrow gap, generating excess electrical current
along with heat and pressure. As a result, developer adheres to the surface of the
development roller and toner accumulation continues, eventually scratching the drum.
