What This Part Does

This transfer belt cleaning blade assembly removes residual toner from the intermediate transfer belt surface and directs waste toner into the waste toner section during operation. When worn or contaminated, excess toner can remain on the transfer belt causing streaks, ghosting, dirty backgrounds, and repeated print defects.

Why Replace the Waste Toner Section?

• Helps maintain a clean transfer belt surface
• Reduces toner contamination inside the printer
• Improves colour print consistency
• Helps prevent repeated toner marks and haze
• Restores proper waste toner collection
• Can improve print quality without replacing the complete transfer belt assembly
