Ricoh Aficio MP C4000 Black Drum Replacement Ideas
Ricoh Aficio MP C4000 Black Drum Replacement – On this page is the guidelines for the drum and developer restoration. Typically once you begin finding color blotches or color back grounding it’s a symptom that the charge grid and cleaning blade are beginning to go bad. A number of businesses offer for sale PM solutions and products to fix the drum units however with the expense of these being reasonably affordable, I’d aim in the direction of merely changing the complete unit because it demands small technical skill level in contrast to rebuilding it which might get difficult and dirty.
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.
