HEATING TO REDUCE DOCUMENT AND Proposed Classification

DOCUMENT BELT CONTAMINATION U~S~CL 271/4 Melvin Crandell mt CL B65h 5/22

In separating and feeding documents, particularly freshly typed originals for producing copies on a copier such as a xerographic reproduction machine, the typing inks smear or transfer onto the sheet-feeding rolls and/or belt This ink may be thereafter retransferred to subsequently fed original documents thereby degrading the document.

With single-strike typewriter ribbon inks, heat causes penetration of the ink into paper, since when heated they become fluid and show good flow properties. Thus by heating the single-strike typed originals prior to feeding through an automatic

document handler, a considerable reduction of smear and set off can be obtained.
