Resolution

Procedure
Refer to Figure 1. Observe the three image areas on several System Controller Test Patterns.
Check the resolution of the images in each of the areas:
Arrow 1
The two pixel vertical, horizontal and diagonal lines should be clear and continuous. The diag-
onal lines might appear to be narrower than the others.
Arrow 2
The text paragraphs should be roughly equal in density.
Arrow 3
The half-tone patches adjacent to the solid blocks in the corners should be uniform in appear-
ance. The three checks (arrows 1, 2, & 3) are within specification.

Registration (Side to Side)

Procedure
Measure the registration on two consecutive System Controller Test Patterns. Fold the paper in
half (top edge to the bottom edge). Observe the fold line of the paper with reference to the
cross hairs of the target, Figure 1. The fold is within +/- 2.0 mm of the target cross hairs
(each line on the target is 1 mm).
Y N
Go to IQ RAP 15 Registration.
The test prints meet the Lead Edge to Trail Edge registration specification. Go to Registration
(Lead Edge to Trail Edge).
