Abstract
Systems, methodologies, media, and other embodiments associated with clearing silicate based kogation from heating resistors employed in ink jet printing are described. One exemplary system embodiment includes a silicate kogation clearing logic configured to pulse the heating resistor at a high frequency and low pulse width to heat the resistor surface to a temperature below that required to form an ink bubble and thus below that required to eject a drop of ink. Heating the resistor facilitates breaking bonds between the silicate based kogation and the heating resistor.
