Registration and Skew

Fold the paper from two consecutive test prints in half (first side edge to side edge and then top
edge to bottom edge). Observe the fold lines with reference to the crosshairs of the printed
target. The fold line should be aligned perpendicular to the target crosshairs and should be
within ±2.0 mm of the target crosshairs (each line on the target is 1.0 mm). If the image does
not meet the criteria, see
