Verify the printed Printhead Position Adjustment Patterns.
Check the lines to confirm if the ink ejects correctly or the specific printhead position is
misaligned.
Look at the columns for each color A to E and determine which horizontal line of each
column aligns with black scale marks, and check the number of the line.
The example below shows that the number of the most appropriate line in the Column
E is +2.
Look at the rows for each color F to J and determine which vertical line of each row
aligns with black scale marks and check the number of the line.
The example below shows that the number of the most appropriate line in the Row F is
–2.
