Abstract

A measuring arrangement and measurement method determine the play of a cartridge pivot unit of an inkjet printing system that has at least one stop for the cartridge pivot unit. The cartridge pivot unit is driven by a first motor via a gear train and is equipped with a first movement sensor to establish a movement of the cartridge pivot unit upon leaving the stop. The cartridge pivot unit moves only when the play of the gear train is overcome. The stop for the cartridge pivot unit is formed by a mobile cleaning and sealing station. A counter is provided to count pulses, the count being representative of the play of the gear train of the cartridge pivot unit counting begins with leaving the mobile stop and continues until the movement of the cartridge pivot unit upon leaving the stop again ensues in conformity with the actuation by the first motor.
