Abstract

With some xerographic printing machines there exists an inability to eliminate contamination cause by additives in color developers. These additives cause xerographic printing machine photoreceptor contamination such as the formation of different types of films on the photoreceptor (i.e. aerosols, zinc stearate, etc. ) that introduce copy quality defects. One known method for removing contaminates is to retain black toner, which contains magnetite, in the fibers of cleaning brushes. Although a toner dusting can be used to "lubricate" cleaner brush fibers, air removal systems impede toner from being retained at the brush fiber tips.

MAGNETIC FLICKER BARS FOR USE WITH PRINTING MACHINE BRUSH CLEANING SYSTEMS(Cont'd)

With some xerographic printing machines there exists an inability to eliminate contamination cause by additives in color developers. These additives cause xerographic printing machine photoreceptor contamination such as the formation of different types of films on the photoreceptor (i.e. aerosols, zinc stearate, etc. ) that introduce copy quality defects. One known method for removing contaminates is to retain black toner, which contains magnetite, in the fibers of cleaning brushes. Although a toner dusting can be used to "lubricate" cleaner brush fibers, air removal systems impede toner from being retained at the brush fiber tips.

To avoid the above noted problems in xerographic printing machine cleaning systems, it is proposed that magnets 20, shown in Figure 1, be used as flicker bars. Cleaning system 2 cleans photoreceptor 10 traveling in direction 12 using pre-clean dicorotron 16 and vacuum cleaning brushes 5 and 6. To compensate for the printing machine color development system using black magnetite toner, the cleaning system uses magnets 20 as flicker bar...
