The two methods to verify registration are:
1. IOT Test Print (see Figure 5.2.2.1)
• Measure 4mm from the top edge (lead edge) of the paper to the top edge of the IOT Test
Print.
• Measure 4mm from the left edge of the paper to the left edge of the IOT Test Print.
NOTE: The ideal registration should measure 4mm in both directions to properly register the test pattern
on the page.
2. System Controller Test Print (see Figure 5.2.3.1.1)
• Fold the top edge (lead edge) of the test print down to the top edge of the scan direction
ladder chart. This folded edge should occur directly on the scan line of the Registration Target
in order to center the scan direction registration. (See Figure 5.2.3.1.1).
• Fold the left edge of the test print over to the left edge of the process direction ladder chart.
This folded edge should occur directly on the process line of the Registration Target in order
to center the process direction registration. (See Figure 5.2.3.1.1).
NOTE: The ideal registration for the System Controller Test Print is for the two fold lines (in the scan
direction and in the process direction) to intersect at the center of the registration target.
