Abstract

In a method and arrangement for data follow-up for warmup cycles of an ink jet print head, a memory stores warmup data of an ink jet print head and a control unit is provided for the driving the ink jet print head and is programmed to implement at least one measurement of the ambient temperature and to access the memory dependent thereon and dependent on predetermined, stored conditions in order to implement a data follow-up corresponding to the temperature-related, history-related and/or user-related conditions for a fast start. Storage of warmup data and data for a first condition ensues upon new installation of an ink cartridge before the first use thereof, and parameter data for second conditions are determined for a fast start given repeated use, and the appertaining warmup data are computationally or tabularly determined given current second conditions.
