Abstract

Disclosed is a measurement technique that quantifies the amount of paper dust in a ream of paper. The method comprises collection of in-ream dust on filter paper as ten reams of paper are shaken into a collector funnel and air is assed through the sheets of paper of the ream and pumped out through the Alter paper region. The filter paper is subsequently weighed and the accumulated ream dust is calculated by difference. Paper dust is responsible for a variety of problems in xerographic printing and copying equipment. For example, copy spotting or poor copy quality, belt and feed roller contamination, photoreceptor contamination, developer contamination and paper jamming. Quantitation of in-ream paper dust content provides a means for improving the reliability and quality of xerographic equipment.
