RECORDING HEAD DRIVING METHOD, RECORDING HEAD, INK-JET PRINTER

摘要

An ink-jet printer comprises a line head having heating elements (121d) for ejecting ink droplets from nozzles. The heating elements (121d) are arrayed generally perpendicularly to the direction where the sheet is fed. The heating elements(121d) corresponding to the nozzles and arrayed spatially are grouped into blocks of predetermined number of heading elements (121d). The line head supplies a phase signal PH to each set of blocks of heating elements to drive the set simultaneously in time-division manner. The dot position error on the sheet is small, and the momentary maximum power consumption during time-division drive is lowered.
