Analyzing Samples - All Models
Inspect these FIXED gap samples for the change in print darkness.
v Proper Darkness and Gap
1. If the FIXED=1 sample is dark, the FIXED=2 sample is light (gray), and the FIXED=3 sample is very light
(with missing dots), the gap and T&D12 value are set correctly.
2. Go to "Gap Check" on page 293.
v Gap Is Too Small
1. If the FIXED=1 sample is dark, the FIXED=2 sample is also dark, and the FIXED=3 sample is light (gray),

2. Using T&D12, increase the T&D12 adjustment value +2, and STORE, to increase the wheel position 0.5.
