Fuser block Until the fusing stage is complete, the image is not permanently affixed to the paper. The toner can be easily smudged until the heat and pressure of the fusing process fix the image to the sheet. Step 6: fusing The toner melts by the heat and pressure as the paper passes through the rollers. The toner image is permanently fused to the paper. The fusing bias is applied to the fuser film to improve print-quality.

drum cleaning The cleaning blade scrapes the residual toner off the surface of the photosensitive drum and toner is deposited in the toner collection box.
