4) Measure the image loss amount (R mm) of the scale image.
Set C = 10 X R (mm). (Example: Set the value of C to 30.)
When the value of C is increased by 10, the image loss is
decreased by 1mm. (Default: 50)
5) Measure the distance (H mm) between the paper lead edge
and the image print start position.
Set A = 10 X H (mm). (Example: Set the value of A to 50.)
When the value of A is increased by 10, the image lead edge is
shifted to the paper lead edge by 1mm. (Default: 50)
6) Set the lead edge void amount to B = 50 (2.5mm).
When the value of B is increased by 10, the void amount is
increased by about 1mm. For 25 or less, however, the void
amount becomes zero. (Default: 50)
