15、onshohocken,PA 19428-2959.United States1 6.4 When making density readings with some densitom-eters,care must be taken that the unit does not damage thesample during the time required to make the measurement.Some units will cause the sample to darken(image).6.5 Machine damage results may occur if the
16、 grade ofthermal paper to be tested is not matched to the requirementsof the facsimile unit given by the facsimile printer manufac-turer.6.6 When evaluating the curl characteristics of the thermalpaper,differences in the diameter of the core and the amount ofpaper on the roll should be considered.Some machines featurerollers that attempt to reverse the amount of curl in the paper.This should also be taken into consideration during theevaluation.6.7 Imaging can vary as a function of the sequence
