Transfer Block; Fixing Block - Canon LBP351 Series Service Manual

■ Transfer block

During the two steps that comprise this block, a toner image on the photosensitive drum is transferred to the print media.
Step 4: Transfer
The transfer bias is applied to the transfer roller to charge the print media positive. The positively charged media attracts the
negatively charged toner from the photosensitive drum surface.
Step 5: Separation
The elasticity of the print media and the curvature of the photosensitive drum cause the media to separate from the drum surface.
The static charge eliminator reduces back side static discharge of the media for stable media feed and image quality.

■ Fixing block

The toner image is fixed onto the print media.
Step 6: Fixing
The printer uses an on-demand fixing method. The toner image is permanently affixed to the print media by heat and pressure.
The fixing bias is applied to the fixing film to improve image quality.
