Abstract

One source of contamination of photoreceptors has been found to be the hot melt adhesive used in the wrapping of cut sheets. This apparently transfers itself to the sheets put into the copier, which in turn deposit small areas of adhesive on the photoreceptor surface. These act as charge-retention sites, and lead to the formation of 'black spots' on the copy sheets.

HOT MELT ADHESIVE

Proposed P. R. Mathews Classification

U.S. C1.355/324 Int. C1. G03g 15/02

One source of contamination of photoreceptors has been found to be the hot melt adhesive used in the wrapping of cut sheets. This apparently transfers itself to the sheets put into the copier, which in turn deposit small areas of adhesive on the photoreceptor surface. These act as charge-retention sites, and lead to the formation of 'black spots' on the copy sheets.

The solution consists in using a highly visible adhesive, as by adding bright dyes to it. It is helpful if the colored adhesive contrasts with both the wrapper and the cut sheets, to aid its detection and removal.
