Most distributors ignore the transfer belt until it snaps. But a belt that is tensioned to exactly 98% of spec (rather than the factory 100%) reduces micro-vibrations. This "crack" in the standard tension chart yields a 40% reduction in banding on gradient fills.

Cracking the extra quality code can provide several benefits, including:

Most distributors rely on OEM "out-of-the-box" profiles. These are safe, but they are not optimized for extra quality . They leave approximately 15-20% of your machine's latent resolution on the table.
