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
vertical c0 line is displaced to the right, you need to move it to the left. Therefore, a value lower than
your actual selection (L=12) is needed.
●
Substrate axis misplacement: The c0 line is displaced to the top. Since the ‘20’ arrow points to the
bottom, if you apply values bigger than your actual value it will be moved to the bottom. This is just
what you want, so a value higher than the actual selection (O=7) is needed.
Zone 2: Printhead to printhead Row1 (versus Row0) alignment check
This area shows the printhead-to-printhead alignment for the second row of color printheads. Each color is
referenced to the same color in Row0. The alignment is correct if no discontinuity or step is detected in any
direction.
As in the description of the previous area, 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 in which the
line will be moved if a ‘20’ value is applied. For example, imagine that in the manual alignment the chosen
value for D is 12, and the chosen value for H is 7. Imagine also a misplacement in the M:
As in the previous zone, increasing D and decreasing H will help to improve the results.
