A heater includes an irradiator configured to irradiate a heating object including a liquid attachment region, onto which a liquid is applied, with an active energy ray, and circuitry configured to control an output of the active energy ray emitted from the irradiator to an edge portion in the liquid attachment region of the heating object to be larger than an output of the active energy ray emitted from the irradiator to a non-edge portion in the liquid attachment region excluding the edge portion.

A continuous inkjet printer (10, 100) has an ink drop generator (12, 112a, 112b) to generate a stream of ink drops (24), deflection means (14, 16, 18, 20, 114, 115, 116, 118a, 118b, 120) to direct each drop of the stream of ink drops either to a gutter (28) or to one of a plurality of default print positions in a stroke direction (30) on a substrate (26, 126), and input means (22, 122) to receive an indication of an offset. The deflection means, in dependence upon the indication of the offset, direct drops that would otherwise be directed to default print positions to offset print positions on a substrate (26, 126), the offset print positions being displaced in the stroke direction 30 by the offset from the default print positions. The input means (22, 122) may also receive an indication of a print height scaling factor and the deflection means (14, 16, 18, 20, 114, 115, 116, 118a, 118b, 120), in dependence upon the indication of the print height scaling factor, direct drops that would otherwise be directed to default print positions to scaled print positions on a substrate (26, 126), the scaled print positions being displaced from the origin in the stroke direction (30) by displacements corresponding to displacements from the origin of the default print positions when scaled by the print height scaling factor.

Provided is an inkjet recording device, including a print head that includes a head base including: a nozzle from which ink is ejected; charging electrodes that charge the ink ejected from the nozzle; deflection electrodes that deflect the ink charged by the charging electrodes; and a gutter that collects ink not used in printing, and a head cover included in the head base, wherein the head base has a first horizontal uneven side portion, an oblique uneven side portion, and a second horizontal uneven side portion.

An inkjet printhead includes two groups of interleaved nozzles. First and second sets of drop-formation waveforms are associated with the groups of nozzles to selectively cause portions of a liquid jet to break off into drops. A timing delay device time-shifts the second-group waveforms relative to those associated with the first-group waveforms. A charging-electrode waveform having portions with first and second potentials is provided to a charging electrode. The waveform energies of the second-group waveforms is larger than the waveform energies of the corresponding first-group waveforms so that printing drops break off from the liquid jets while the charging-electrode is at the first potential, and non-printing drops break off from the liquid jets while the charging-electrode is at the second potential.
