How to Judge
Examine the printout patterns and enter the value (-10 to 10) for the most straight lines.
Additional information
In the following cases, reassemble or replace the Printhead and carry out the
adjustment again.
The difference between the adjusted values of 1 -> 80 and 80 -> 1 exceeds 8.
The larger the difference is, the more the Printhead is tilted in the front-to-
back direction. (Not parallel to the paper surface.)
The average of the values of 1 -> 80 and 80 -> 1 falls outside the range from -
4 to +4.
The further the value is beyond the range, the more the Printhead is tilted in
the left-to-right direction. (Not parallel to the paper edge.)
