Step 4: Transfer The positive DC bias is applied to the transfer roller to charge the media positive. The positively charged media attracts the negatively charged toner from the photosensitive drum surface. Figure 5-18 Transfer Photosensitive drum Transfer roller Media DC bias Step 5: Separation The curvature elasticity of the print media causes it to separate from the photosensitive drum surface. The static charge eliminator reduces back side static discharge of the media for stable media feed and image quality. Figure 5-19 Separation Photosensitive drum Static charge eliminator Transfer roller Media Block 4: Fusing The toner image is fixed onto the print media. 118 Chapter 5 Theory of operation ENWW

Step 4: Transfer
The positive DC bias is applied to the transfer roller to charge the media positive. The positively charged
media attracts the negatively charged toner from the photosensitive drum surface.

Step 5: Separation
The curvature elasticity of the print media causes it to separate from the photosensitive drum surface.
The static charge eliminator reduces back side static discharge of the media for stable media feed and
image quality.
