Abstract

A photoreceptor cleaning composition is provided which comprises a blend of halogenated hydrocarbons, which exhibit no flash point, TAG Open Cup, ASTM Method D-l310, and a petroleum hydrocarbon having a closed cup flash point of over about 135°F. During use a photoreceptor of a commercial copier becomes contaminated with residual toner particles and paper tars resulting in image deterioration, The composition set forth above is found to result in good cleaning of the closely held contaminants of the photo- receptor. The composition as set forth above does not require the use of an abrasive with the cleaning solvent and therefore does not cause deterioration of the photo- receptor,

A photoreceptor cleaning composition is provided which
comprises a blend of halogenated hydrocarbons, which exhibit
no flash point, TAG Open Cup, ASTM Method D-l310, and a
petroleum hydrocarbon having a closed cup flash point of
over about 135°F. During use a photoreceptor of a commercial
copier becomes contaminated with residual toner particles
and paper tars resulting in image deterioration, The
composition set forth above is found to result in good
cleaning of the closely held contaminants of the photo-
receptor. The composition as set forth above does not
require the use of an abrasive with the cleaning solvent
and therefore does not cause deterioration of the photo-
receptor,

The halogenated hydrocarbon and petroleum are generally
employed in a ratio of from about 99:1 to 50:50 halogenated
carbon to petroleum distillate, A preferred ratio is 93:7
halogenated hydrocarbon to petroleum distillate,

An example of a cleaning composition in accordance with
this disclosure is about 90 parts by volume of, Dow Chemical
Company, Chiorothene NU 1,1,1 trichioroethane mixed with
about 10 parts by volume of, APCO Oil Company, APCO-l40 a

petroleum distillate having a petroleum hydrocarbon fraction
with a distillation range of from 358°Fto 409°F to
provide the cleaning composition.
