摘要： A flushing method for a fluid ejecting apparatus that includes a pressure chamber filled with fluid, a pressure generating element on a surface of the pressure chamber that deforms the surface to change the pressure in the pressure chamber, and a nozzle in fluid communication with the pressure chamber that ejects the fluid, the method including repeatedly performing first flushing process a first period; and repeatedly performing a second flushing process with a second period. The flushing processes include causing the pressure chamber to expand into an expanded state, maintaining the expanded state, and contracting the pressure chamber from the expanded state, causing the fluid to be ejected from the nozzle. The amount of fluid ejected from the nozzle in the second flushing process is larger than the amount ejected in the first flushing process.

摘要： A fluid ejecting apparatus that ejects fluid includes a control unit that generates a drive pulse and a temperature detection unit that detects at least one of an environment temperature and a temperature of a fluid ejecting head. The control unit is able to generate a maintenance drive pulse for ejecting a bubble together with the fluid from a pressure chamber. The maintenance drive pulse includes a first pulse portion that cause the pressure chamber to expand into an expanded state, a second pulse portion that causes the pressure chamber to contract from the expanded state, and an intermediate pulse portion placed between the first pulse portion and the second pulse portion for holding the expanded state of the pressure chamber. The control unit adjusts the width of the intermediate pulse portion on the basis of the temperature detected by the temperature detection unit.

摘要： A drive signal generator generates a drive signal including a first waveform component for jetting an ink drop to be a micro dot and a second waveform component for jetting an ink drop to be a middle dot. A pressure generating element varies the volume of a pressure generating chamber in accordance with the drive signal to jet an ink drop from a nozzle orifice. An ink drop to be a large dot is jetted from the nozzle orifice when the first waveform component and the second waveform component are consecutively applied to the pressure generating element. A time interval T&mgr;m between an end point of the first waveform component and a start point of the second waveform component is set so as to substantially satisfy the following equation: T ⁢ ⁢ μ ⁢ ⁢ m = n 2 ⁢ Tc here, Tc denotes a natural period of the pressure generating chamber.

摘要： An ink jet recording apparatus which jets out a plurality of ink droplets at a predetermined cycle within a single drive period and such that the ink droplets are combined in the air to form a single ink droplet which is supplied to a recording sheet. A charge pulse generating circuit and a discharge pulse generating circuit which divide a drive period into a plurality of segments and output a pulse signal, having cycle Tp which is larger than the Helmholtz cycle Tc, in synchronism with an auxiliary print signal. A time constant adjusting circuit changes an output waveform of a constant current circuit with the pulse signal to increase the velocity of an ink droplet last jet out so that the velocity of the ink droplet allows the ink droplet to be combined, in the air, with an ink droplet previously jet out.
