Gestetner MP C5000 Black Drum Replacement Points

Gestetner MP C5000 Black Drum Replacement – On this page are the directions for the drum and developer replacement. Usually when you start viewing color blotches or color back grounding it is a indicator that the charge grid and cleaning blade are starting to go bad. A couple of companies offer for sale PM solutions and products to restructure the drum units however with the price these appearing moderately low cost, I would personally aim in the direction of simply swapping the entire unit mainly because it involves little technical skill-set unlike restoring it which can sometimes get complicated and messy.

Note : Majority of print quality problems are related to parts of the drum unit. In most cases, the developer last twice as long as the drum units and unless your really focused on print quality you will rarely notice developer issues until it’s extremely low. The steps below included directions for both replacement procedures. Therefore, if you are just replacing the drum unit make sure you don’t follow the steps past Note and I would even question the need of doing step 8.
