Abstract:
A system for use with a phase change ink imaging device comprises a leveler roller disposed along a web path downstream from a printing station. The leveler roller is formed of a thermally conductive material and includes a heater configured to generate thermal energy to heat the leveler roller to a leveling temperature. The leveler roller is positioned to be partially wrapped by the continuous web in order to generate a predetermined dwell time between the continuous web and the leveler roller as the continuous web is being moved. The predetermined dwell time is configured to allow conductive heat transfer to occur between the continuous web and the leveler roller to equalize the continuous web and the melted phase change ink temperatures on the web to within a predetermined range about the leveling temperature. A midheater is disposed along the web path downstream from the leveler roller. The midheater is configured to heat the continuous web and the melted phase change to a midheating temperature that is greater than the leveling temperature.
