Analyzing samples
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&D08 value are set correctly.
2. Go to Gap check.
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),
you should create a FIXED=4 sample. The FIXED=4 sample should appear light, and exhibit some missing
dots.
2. Using T&D08, increase the T&D08 adjustment value +2, and STORE, to increase the wheel position 0.5.
3. Rerun the samples to verify satisfactory results. After you are satisfied with the results, go to Gap check.
v Gap is too large
1. If the FIXED=1 sample is light, the FIXED=2 sample is very light (missing dots), and the FIXED=3 sample is
unreadable (due to lightness) the gap is too large.
2. Using T&D08, decrease the T&D08 adjustment value -2, and STORE, to decrease the wheel position 0.5.
3. Rerun the samples to verify satisfactory results, and go to Gap check.
Gap check: Perform this check only after completing the Power Off Check, the "Power On Check" on page 155,
and the Print quality check.
