Lanier LD528C Magenta Drum Replacement Guidelines

Lanier LD528C Magenta Drum Replacement – Listed here are the directions for the drum and developer repair. Usually when you begin noticing color streaks or color back grounding it’s a symptom that the charge grid and cleaning blade are beginning to go bad. A small number of businesses produce PM solutions to restore the drum units although with the value of these appearing relatively low-cost, I’d personally lean in the direction of actually replacing unit considering it takes low technical ability when compared to reconstructing it which often can get tricky 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.
