摘要:
An ink-jet recording apparatus having an ink-jet recording head (7, 8) including pressure generating chambers (49) communicatively connected to a nozzle opening (52) and a reservoir (50), pressure generating means (42) for pressurising the pressure generating chambers (49), and control means for applying drive signals corresponding to print data to the recording head and for minutely vibrating meniscuses of ink in the nozzle openings to such an extent as to not eject ink droplets during a nonprint period. The control means ejects ink droplets from the nozzle openings in accordance with print data during printing operations, and minutely vibrates meniscuses of ink formed at the nozzle openings a pre-set period of time before or after the discharging of the ink droplets in a printing operation. Minutely vibrating means (23, 42, 69) are provided which vibrates the meniscus present at the nozzle opening in succession for a preset period T2 at every period T1 interval when the ink jet recording apparatus is in a non-print operation.
