The present invention relates to an ink jet ink which is an oil-based white ink for ink jet recording containing (a) titanium oxide having an average particle size of 0.15 to 0.25 &#x3bc;m, (b) a resin, (c) an organic solvent and (d) a nonionic surfactant, wherein the nonionic surfactant comprises at least one member selected from polyoxyethylene alkyl ethers and polyoxyethylene phenyl ethers. According to the invention, there can be provided an oil-based white ink for ink jet recording which is excellent in ejection stability and in recovery properties after standing for a long period of time.

Oil-based white ink for ink jet recording

A timing signal generator generates an ejection timing signal each time a printing paper travels a predetermined distance relative to a head, and a driving signal generator inputs a driving signal based on writing data to the head each time an ejection timing signal is generated. In the course of printing, when an interval between two continuous ejection timing signals is equal to or longer than twice a basic time period of input of driving signal which is fixed for a head, a non-ejection driving signal which is a driving signal indicating a non-ejecting operation is input to the head between two driving signals respectively associated the two continuous ejection timing signals. Accordingly, it is possible to reliably and properly perform ejection of ink based on writing data with a time period equal to or longer than the basic time period.

Printing method and printing apparatus

In a head unit of a printer, a head (A) has outlet rows (and) arranged along a first tilt direction and a gap between outlets in the outlet rows (and) is interpolated with a outlet in the outlet rows (and) by a slight tilt. A head (C) adjacent to the head (A) is tilted in a second tilt direction opposite to the first tilt direction. In the printer, a plurality of dots are formed, being aligned on a piece of printing paper in the first tilt direction by performing an ejection control simultaneously for all outlets in each outlet row of the head (A) and subsequently a plurality of dots are formed, being aligned on the piece of printing paper in the second tilt direction by performing an ejection control simultaneously for all the outlets in each outlet row of the head (C), to make both rows of dots continuous. Through this operation, the printer can easily perform high-resolution printing without such a complicate ejection control as to control ejection of ink for each outlet ().

An ink jet recording device includes an external switch, a device for detecting the amount of ink left in each ink cartridge, and a device operating such that when an instruction to replace the ink cartridge is generated by the switch, or when a device detects an ink end of the cartridge, only the ink cartridge to be replaced is exposed through a window in the recording device. The ink cartridge to be replaced is specified, and only the specified ink cartridge is automatically moved to a replaceable position. Correct replacement of more than one ink cartridge is ensured, and the cartridge replacing work is simplified.

Ink jet recording device

Ink is sucked in a first amount from recording heads by applying negative pressure of suction pumps to the recording heads in a state in which communication between the recording heads and the atmosphere is cut off by sealing the recording heads by means of caps. The ink in the caps is then discharged by causing negative pressure of the suction pumps to act in a state in which the caps are made to communicate with the atmosphere, and then wiping is effected by a wiping blade.

Ink-jet recording apparatus

Cap holders (,) are accommodation in a holder receiving member (,) in such a state that the cap holders are urged by springs toward the side of a recording head at two places with inclinations at angles of &thgr;1, &thgr;2 in the moving direction of a carriage and at an angle of &thgr;3 in a direction perpendicular thereto. Moments are produced by giving a difference to the distance between the whole periphery of a cap and the recording head, and peeling is effected from one point, so that the sealing of the recording head and the peeling of the cap off the recording head are made compatible.
