Abstract

In a method or system to operate a digital printer for double-side printing to a recording medium with toner particles applied with a liquid developer, the digital printer prints first and second sides of the recording medium in succession. Electrophoretic mobility of toner particles of a first toner image on the first side is reduced after application of said first toner image and before application of the second toner image on the second side of the recording medium. The electrophoretic mobility is reduced by drying the first toner image along a drying route in an airflow generated by a blower such that carrier fluid is thus removed from the first toner image. After the application of the second toner image on the second side of the recording medium, both the first and second toner images are simultaneously fixed.
