Visual Alignment Diagnostic Print
This print helps you to check any alignment problems of the printer.
You can use it to measure the alignment error with an accuracy of one dot row.
The print is split into three areas. The first two are the same print, printed at different speeds: 40 and
60 ips to check most of the printhead alignment. The print modes associated with these speeds are
shown in the following table:
