I have seen the speed variance chart you have on the different Wave modes, however there is no documentation on your site, or manuals, regarding the technical differences between your Wave modes.

So far, there are no hard and fast rules for choosing a Wave and mode.
With all the variations in media, profiles and operating conditions, this is proving to be a daunting task.

Most applications benefit from Wave 1 or Fine and Wave 1.

Difficult media may be helped by Wave 2, 3, or 4 and fine.

If you want to see the differences in the wave, print a dark print and stop the printer before completion
You can look at the number of passes and the way the dots are layed down.

We should have additional information in the coming months.
