Lanier LD520CL Black Drum Replacement
Lanier LD520CL Black Drum Replacement – Below are the guidelines for the drum and developer repair.

Several suppliers provide PM kits to reconstruct the drum units however with the price of these appearing somewhat economical, I would personally lean in the direction of actually replacing unit as it takes minor technical expertise as opposed to rejuvenating it which can often become tricky and dirty.
