Abstract

Aerosol (spray) adhesives are a potential photoreceptor con taminant that may afnict mid to high volume copid in the field. Wiper blade technology has neutralized the majority of photoreceptor contamination types, but has limited success in removing the ultra small, ultra sticky, 10-100 micron diameter adhesive spray particulates. Such particulates can ultimately find their way to the photoreceptor causing print out spot defects.

Aerosol (spray) adhesives are a potential photoreceptor con taminant that may afnict mid to high volume copid in the field. Wiper blade technology has neutralized the majority of photoreceptor contamination types, but has limited success in removing the ultra small, ultra sticky, 10-100 micron diameter adhesive spray particulates. Such particulates can ultimately find their way to the photoreceptor causing print out spot defects.

It is proposed that a chemically stabilized electrostatically charged fiber meshed fabric membrane be installed both at normal portal machine air stream filter entry points and as
liners on interior machine surfaces which also contact air intake access routes to the machine paper drive train and photoreceptor housing.

Mid and high volume copiers have a number of cooling fans which both draft air into the machine at filter protected portal locations to cool electronics, but also create a localized negative pressure environment about the machine that attracts potential aerosol con taminant containing air flow to enter the machine through unguarded areas.

It is proposed that these unguarded areas, primarily at the base of the machine and around the paper drive train be protected by lining the interior machine structural surfaces, where feasible, with thin fabri...
