  • CONTROL OF AIR-BASED MEDIA DRYER
    Publication number: 20140225955
    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.

  • Methods and apparatus for ink drying
    Patent number: 8646899
    Abstract: Ink drying methods and apparatus are disclosed. One example ink drying apparatus includes a resistive heating element having a first power dissipation density adjacent to a center region of a print media travel path and a second power dissipation density adjacent to an edge region of the print media travel path, wherein the first and second power densities are not equal.

  • Ink drying apparatus, methods to control ink drying apparatus, and power control apparatus to control ink drying elements
    Patent number: 8487219
    Abstract: Ink drying apparatus and method for controlling ink drying apparatus are described herein. An example ink drying apparatus includes first and second heating elements positioned adjacent a drying area in a printer, and a controller to determine a temperature of the heating area and to selectively operate, based on the temperature determination, the first heating element in a burst mode and the second heating element in an on/off mode.
