Registration Measurement
Perform dC126, make selections to print the test pattern on A3 or 11x17 inch paper.
Use the measurements Sa and Sb at each end of the inboard edge to measure the displace-
ment of the top of the image from the paper inboard edge, refer to
Use the measurements La and Lb at each end of the lead edge to measure the displacement
of the side of the image from the paper lead edge.
NOTE: If a there is a difference between any pair of measurements, refer to
Corrective Action
Perform dC126 System Registration.

Use the grids A and B on the copy, Figure
compared to the test pattern. Use the grid C to measure the top edge displacement. The dis-
placement measured at A and B should be equal.
NOTE: Grid A and grid B of test patterns 82E2000, 82E2010, 82E2020 are small areas of par-
allel lines 1mm apart. These can be used to directly measure the registration displacement.
NOTE: If a there is a difference between measurements at A and B, refer to
Corrective Action
As necessary, perform ADJ 60.2 IIT Lead Edge Registration or
