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 block
