Determine the image magnification factor using the following
formula:
Image magnification factor (%) = Copy dimension / original
dimension x 100
Image magnification factor (%) = 99 / 100 x 100 = 99
If the image magnification factor is within the spec (100 ±
0.8%), no adjustment is required; otherwise, do the following
steps.
