1. Adjustment
and
Verification
18. Execute "Repeatability"
This makes three 1-pass bi-directional scans and compensates for
the offset of the second scan (CCW printing) relative to the first and
third scans (CW printing).
19. Check the printing, first for black then for colour, and record a posi-
tive increment if the second scan (CCW printing) is offset towards
the cap side, or a negative decrement for the opposite direction.
(Repeat the printing after the registration.)
Repeat until both directions are aligned.
20. When repeatability printing position alignment has been achieved,
proceed with the “Repeatability (Microdot)” adjustment in the same
manner.
21. Execute "Unidirectional".
This corrects the initial printing position (5 mm from media edge)
and compensates for the position of Head 2 relative to Head 1
(head pitch).
22. With a steel ruler, measure from the edge of the media to the posi-
tion of the black printing and enter the measured value.
