Abstract
Examples are provided of controlling sheet media dryers. A controller operates a fan at plural duty cycles and correlates a resulting air pressure to each to define empirical data pairs. A parabolic curve fit to the empirical data is used to derive additional data pairs, and a lookup table is defined using the empirical and derived data pairs. The controller uses the lookup table to operate the fan during normal operations of a sheet media dryer.
