Manual BiDi Registration

4-12
Bidirectional registration is a method to align each of the print-
heads so that dot placement is accurate in both directions along
the X axis (along the direction of printhead travel).
The bidirectional registration pattern consists of a series of verti-
cal lines. Half the pixels in this pattern are printed in one direc-
tion, half of them in the other direction. When the pixels are
accurately aligned, the pattern is clear. When the dots are not
aligned, the pattern appears fuzzy and ill-defined.
Note AutoBiDi Calibration is the automatic version of this
calibration. Try AutoBiDi first before running this
manual calibration (see "Auto Calibrations" on page
4-6 for details).
