5. Check the test pattern and find the optimum adjustment value.
• The adjustment patterns consist of outbound pass lines and return pass lines for each color. [A]
consists of lines for the outbound pass, and [B] consists of lines for the return pass. Adjustment
values (-5 to 5) are printed on return pass lines.
• This test pattern is printed using only the print heads for the first row. The pattern is identical for
the adjustment patterns for Cyan, Magenta, Yellow, and Black. Therefore, only check the
adjustment pattern for Cyan.
• Find the pattern where outbound pass lines and return pass line are overlapped and aligned to
form one straight line, and then check its adjustment value. In the following case shown below, "2"
is the optimum adjustment value.
