Description
Abstract:	SUMARRIES. This paper describes two on-site test procedures and an instrumental procedure for evaluating copy quality. The results are compared to criteria defined in the ASTM Method D-3458 for copy quality. Test copies were subjected to artificial aging techniques and the copy quality evaluated. CONCLUSION. 1. Even though the results shown have not been clear cut, the tape peel or rub tests are recommended as on-site copy evaluation techniques. 2. The toner is the more stable component of the paper and toner pair. 3. An "archival quality" paper, as defined in the Part 1 of the ASTM Method D-3458 should be used to ensure a more permanent xerographic product. Accelerated aging using heat is unsuitable for combination studies of paper and toner. Heat tends to set the toner onto the paper more. If heat is used to fix the toner more tightly on a questionable copy, be aware that heat degrades the properties of paper. That is, the strength properties tend to decrease when using heat accelerated aging techniques. 4. Keep the copier machine well maintained. In particular, the copier should operate at the optimum temperature to insure the toner will melt properly and flow into and around the cellulose fibers. 5. Because of the nature of toners (even without heat they tend to flow), copies should not be stacked with any great amount of pressure. The image will migrate from the original, especially at elevated temperatures. 6. Xerographic copies should also be kept away from vinyl surfaces as the image will migrate because of the thermoplastic nature of toner. 7. Finally, of the fourteen copying systems examined, twelve systems had mixed "pass and fail" results on each of the copy evaluation procedures. Panasonic FP 3002 consistently failed all the tests, while the Kodak Ektaprint 85 system passed all the tests.
