CHAPTER 2
6. Fixing block
The toner image transferred onto the paper in the transfer block is held only by electrostatic
attraction, so even a light touch will smear the image.
In the fixing block, the four color toners are melted and mixed by heating the paper and
applying pressure to make a permanent image.
Step 10 Fixing
The upper and lower roller surfaces are covered with the Teflon tube with very low sticking prop-
erty.
The negative DC bias is applied to the upper fixing roller to prevent adhesion of the toner on
the paper onto the roller surface.
