Zone 1: Printhead Row0 alignment check (closer to the substrate output)
This area shows the printhead-to-printhead alignment for the first row of color printheads. Each printhead
has crosses, where it is compared to a reference printhead. In this case the black printhead has been chosen
as a reference.
The colors are labeled C0, M0, Y0, c0, m0, where the ‘0’ specifies that it is the first row of printheads. In each
case, the inner cross should be aligned with the outer cross.
In case of misalignment the arrows indicate the pattern of the manual alignment that will correct the
misalignment. Also, the ‘20’ label indicates the direction towards where the line will be moved when a ‘20’
value is applied. For example, imagine that in the manual alignment the chosen value for L is 12, and the
chosen value for O is 7. Imagine also a misplacement in the c0:
● Scan axis misplacement: The c0 line is displaced to the right. Since the ‘20’ arrow points to the right, if
you apply values bigger than your actual value it will be moved further to the right. But, since the
