Abstract
An apparatus for loading one or more donor rolls of a developer unit, comprising a developer housing having a reservoir for a developer material, a rotatable first donor roll that delivers the toner onto a moving photoconductive member, a trim roll that receives developer material from the reservoir and delivers the developer material to a first magnetic brush roller that delivers toner to the first donor roll, and a rotatable second magnetic brush roll that receives the developer material from the first magnetic brush roll and delivers the toner to the first donor roll. The apparatus may further comprise a rotatable second donor roll that receives the toner from the second magnetic brush roll and delivers the toner onto the photoconductive member, and a rotatable third magnetic brush roll that receives the developer material from the second magnetic brush roll and delivers the toner to the second donor roll. The apparatus may further comprise a trim blade for trimming excess developer material from the trim roll.
