2) Open the original cover and make a normal (100%) copy.
3) Measure the width of the black background at the lead edge and at
3) Measure the width of the black background at the lead edge and at
the rear edge.
If the width (La) of the black background at the lead edge is equal that
(Lb) at the rear edge, there is no need to execute the following
procedures of 4) - 7).
