Image Transferring and Media Separation
During the image transferring process, the toner image on the drum surface
is transferred to the media. A positive charge applied to the back of the
media by the transfer roller, causes the negatively charged toner particles
on the drum surface to be attracted to the media.
The small diameter of the drum, combined with the stiffness of the media
cause the media to separate easily from the drum. The static eliminator
teeth also help separate the paper from the drum. The static eliminator
teeth weaken the attractive forces between the negatively charged drum
surface and the positively charged paper. This action keeps thin media from
wrapping around the drum. After separation, the drum is cleaned and
conditioned for the next image.
