Fusing stage
Until the fusing stage is complete, the image is not permanently affixed to the print media. The toner
can be easily smudged until the heat and pressure of the fusing process fix the image to the sheet.
Step 7: fusing
The product uses an on-demand fusing method to fuse the toner image onto the media. The toner image
is permanently affixed to the print media by the heat and pressure.
