Manual Straightening of Lines and Colors (Manual Head Adj)

If printed vertical lines are warped or colors are out of alignment, adjust the Printhead alignment.
With Manual Head Adj, you can manually adjust the Printhead alignment by printing and reading a test pattern.
You can adjust the Printhead alignment automatically or manually. Normally, choose automatic adjustment. If advanced
adjustment does not improve printing results, or if you are using special paper, try manual adjustment. For instructions on
straightening lines and colors automatically, see "Automatic Straightening of Lines and Colors (Auto Head Adj.)."
