Abstract: In general, according to one embodiment, an inkjet recording apparatus includes an inkjet head, a conveyance motor, a discharge motor, a printing medium surface sensor and a controller. The inkjet head ejects ink on a printing medium. The conveyance motor causes conveyance of the printing medium. The discharge motor causes discharge of the printing medium. The printing medium surface sensor, locates at the upper-stream side of the inkjet head apart from the inkjet head in a printing medium conveyance direction, senses a foreign substance representing an image printed on the printing medium beforehand. The controller drives the discharge motor to discharge a printing medium without ejecting ink from the inkjet head if an after-printing mode in which printing is made on the printing medium on which the image is printed beforehand is not set if the foreign substance is detected on the printing medium through the printing medium surface sensor, or drives the discharge motor to discharge a printing medium after ejecting ink on the printing medium from the inkjet head if the after-printing mode is set if the foreign substance is detected on the printing medium through the printing medium surface sensor.

Abstract: An air removing device is connected to a tank to contain ink through a first supply tube, and an ink-jet head is connected to the air removing device through a second supply tube. The first supply tube and ink-jet head are heated and controlled. Air dissolved in ink is sucked out through a hollow fiber membrane provided in a housing by operating a vacuum pump by supplying ink to the hollow fiber membrane while heating and controlling atmosphere in the housing. Thus, air dissolved in ink is removed, and ink heated to a temperature suitable for ejection is supplied to the ink-jet head.

Abstract: An ink evaluation method of the present invention comprises: a first step of making a given amount of solution pass through a filter and measuring time for the solution to pass through the filter; a second measurement step of making pass through the filter the ink having a solid material dispersed in a solvent and having the same viscosity and the same amount as those of the solution, and measuring the time for the ink to pass through the filter (filter passing time); a calculation step of calculating a ratio of the filter passing times between the solution and the ink; and a determination step of determining whether the ink discharging stability index is high or not based on the measured ratio. Thus, since the ink having a high spraying stability index can be easily determined, ones having the high spraying stability index out of plural types of ink may be selected.

Abstract: In a method of driving a plurality of ink jet heads, each ink jet head comprises a plurality of ink chambers that are each provided with an ink nozzle. The ink nozzles of each of the ink jet heads are divided into N sets each including every N-th ink nozzle, where N is an integer of two or more, and the N sets of the ink nozzles are arranged in parallel longitudinal rows in a staggered arrangement. The respective ink nozzles in corresponding rows of the ink jet heads are spaced apart from each other by a distance equal to an integral multiple of a pitch of the rows of the ink nozzles in each of the ink jet heads in a sub-scanning direction in which a recording medium is moved, and the ink nozzles eject ink as the ink nozzles move relative to the recording medium in a main scanning direction perpendicular to the sub-scanning direction. The ink nozzles of each of the N sets are driven to eject ink on a same line on the recording medium, by controlling a timing at which the ink nozzles of each set are driven and a relative speed between the ink jet heads and the recording medium. When an amount of misalignment between dots recorded by a reference set of the ink nozzles and dots recorded by another set of the ink nozzles exceeds one-half of a dot pitch defined in the sub-scanning direction, an order in which the sets of ink nozzles are driven is changed to reduce the amount of misalignment between dots to below one-half of the dot pitch defined in the sub-scanning direction.
