摘要： A printer includes first transporting belts disposed in parallel at predetermined intervals in the direction intersecting the direction of transportation of print media. The first transporting belts transport a print medium while adsorbing the print medium. Second transporting belts disposed in parallel at predetermined intervals in the direction intersecting the direction of transportation of print media further transport the print media. The second transporting belts are separated from the first transporting belts at the downstream part of the first transporting belts in the direction of transportation of print media. A print head prints on the print medium. The position of separation at which the print medium is separated from the first transporting belts is different in the direction of transportation of print media between one of the first transporting belts and another one of the first transporting belts.

摘要： A head drive of an inkjet printer includes nozzles and corresponding actuators that eject liquid ink drops. A drive unit applies a drive signal to the actuators. The drive unit includes a drive waveform generator that generates a drive waveform signal to control the drive of the actuators. A modulator pulse modulates the drive waveform. A digital power amplifier amplifies power of the modulated signal. A low pass filter smoothes the amplified digital signal and supplies the signal as a drive signal to the actuators. An inverse filter provided in a subsequent stage of the drive waveform generator corrects at least the frequency characteristics of the filter to predetermined frequency characteristics, independent of the number of the actuators to drive.
