of the image (D). These two measurements should be equal (Figure 1).
• Measure the distance from the lead edge of the paper to the lead edge of the image
(A) and measure the distance from the trail edge of the paper to the trail edge of the
image (B). These two measurements should be equal (Figure 1).
