Abstract

Adjusting a copier's magnetic brush core orientation relative to a line connecting the core and photoconductor drum centers allows large carrier bead chains to scavenge large toner agglomerates (clinkers) from the photoconductor surface and thus prevents the permanent development of same onto the surface of the photoconductor.

Eliminating Clinkers by Magnetic Brush Adjustment

Adjusting a copier's magnetic brush core orientation relative to a line connecting the core and photoconductor drum centers allows large carrier bead chains to scavenge large toner agglomerates (clinkers) from the photoconductor surface and thus prevents the permanent development of same onto the surface of the photoconductor.

Deleterious splotches appear on solid or halftone copies when toner particles
(1) fuse or lump together into large particles exceeding normal toner particle size, and (2) are developed onto the photoconductor surface. For example, copiers designed for toner up to 20 Mu occasionally have clinkers larger than 50 Mu. In such a copier, clinkers are scavenged from the photoconductor surface when the angle Theta between the core-to-drum centerline 1 and a line 2 between two magnet ends is about 7 Degrees Plus-Minus
