The transparency sheet is printed with sets of vertical lines in seven columns,
each showing the results from a different print head.
Figure 4-64 Sample head-alignment test
Note:
There is no column for head H7 because its alignment is used as a
reference for aligning all other heads.
8. For each column of lines, use a magnifying glass or loupe to inspect pairs of
consecutive rows printed on the transparency to see where the vertical lines
align.
Figure 4-65 Comparing rows of alignment lines
Note:
It does not matter which pair of lines you inspect, since they were all
printed by the same head. Choose a pair of clearly printed lines for the
inspection. (Since some nozzles may not print clearly, you may have to
inspect several pairs of lines to properly view the alignment.)
Optimum head alignment is shown when the
fourth
lines in the upper and
lower rows are aligned, as in Figure 4-65. In the example shown, no change
to the head alignment is necessary. If other lines in the set are aligned, you
need to change the alignment of that head—in the next wizard screens.
