Bidi registration

Head 1: +2

If a printhead is extremely out of alignment, there may be no pattern in alignment. Since the parallel bars are nominally five pixels apart, you can add +5 or -5 to a pattern number to shift the colored bars right or left by one bar. Alternatively, you can perform the BiDi Registration repeatedly, which will move the head in smaller increments, until the head is aligned.

6.Press ! (Proceed).
