<P>PROBLEM TO BE SOLVED: To appropriately adjust at least one of a voltage value and a waveform of a voltage waveform even if the printing speed is increased. <P>SOLUTION: An inkjet printer 10 comprises: a head input changing means for changing a voltage waveform to be input to an ink ejection head 14a when a nozzle surface 20a is disposed opposite a first gap G1; a temperature sensor 90 measuring a first actual temperature of the ink ejection head 14a when the nozzle surface 20a is disposed opposite a second gap G2; and a first estimated temperature calculation means for calculating a first estimated temperature of the ink ejection head 14a when the nozzle surface 20a is disposed opposite the first gap G1 on the basis of the first actual temperature and an ink ejection history of ink ejected to a sheet P located between the first gap G1 and the second gap G2. The head input changing means changes the voltage waveform on the basis of the first estimated temperature. <P>COPYRIGHT: (C)2013,JPO&INPIT |
