Ink droplet ejection apparatus and ink jet recorder

摘要

An ink droplet ejection apparatus includes a print head having ejection nozzles and three storers store serial ejection data therein and transfer them in order. On the basis of the data output from the storers and transfer data control signals, a transfer data generator makes a logical operation to generate additional pulse data for cancellation of ink pressure wave vibration in order to prevent ink from being ejected or dropped accidentally through the nozzles. The control signals are determined depending on temperature and condition of use.
