■ 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.
Configuration of the Fixing Film is self-bias film (keep the surface of the Fixing Film charged with negative potential by contact
with diode) to improve image quality.
