摘要： A printing apparatus is provided with a line-type ink jet head having a plurality of blocks on each of which a set of ink ejection elements are arranged. A drive signal generating unit is configured to generate a drive voltage signal including a prepulse to be applied to the set of the ink ejection elements for each block, based on data indicating a number of times of ejecting ink to each pixel; and a first storage unit is configured to store a drive signal adjustment value to adjust a set of a voltage value of the drive voltage signal and a width of the prepulse for each block. The drive signal generating unit generates the drive voltage signal for each block, based on the drive signal adjustment value for each block read out from the first storage unit.

摘要： A printing apparatus is provided with a line-type ink jet head having a plurality of blocks on each of which a set of ink ejection elements are arranged. In the printing apparatus, a drive voltage signal is accompanied with a prepulse to be applied to each ink ejection element. Particularly, drive signal adjustment values are stored in association with each block. The drive voltage signal is generated for each set of ink ejection elements with reference to the drive signal adjustment values in association with the block on which the each set of ink ejection elements are arranged. By this configuration, it is possible to reduce the differential density between the image portion printed by the imperfect block having misaligned nozzles and the image portion printed by the normal block having nozzles arranged in their correct positions throughout the density range.

摘要： An inkjet printer includes an inkjet head configured to perform printing on a printing sheet by use of ink. The inkjet printer includes: a heater configured to heat the ink; a thermometer configured to measure the temperature of the ink; and a controller configured to control the amount of electric power to be supplied to the heater and to control the inkjet head. In a case where the measured value of the ink temperature measured by the thermometer is in a range of a first reference temperature inclusive to a second reference temperature exclusive, the controller calculates a coverage rate of a page to be printed, and accordingly changes the amount of electric power to be supplied to the heater depending on the coverage rate thus calculated.

摘要： An ink jet printer performs a print process by ejecting ink for each of a plurality of ink colors. When a predetermined first circulation time elapses after starting the ink circulation, an ink agitating operation drive signal generation unit applies an ink agitating operation drive signal to an ink ejecting unit set operable to eject an ink, which has a predetermined nature, for a first ink agitating operation time in a first period, and applies the ink agitating operation drive signal to an ink ejecting unit set operable to eject an ink, which has not the predetermined nature, for a second ink agitating operation time in a second period which is shorter than the first period. It is therefore possible to perform maintenance effectively in advance of starting the print process in accordance with the nature of ink.

摘要： An inkjet recording device has an ink tank, a reservoir and an ink head, forms an ink supplying system by connecting with a path between the ink tank and the reservoir and between the reservoir and the ink head respectively, and forms a meniscus by generating a negative pressure on an ink discharging plane of the ink head by opening the reservoir to atmosphere. The inkjet recording device includes control electromagnetic valves to open or interrupt paths of the ink supplying system and valve switching control means for controlling opening/closing of the control electromagnetic valves, and controls the valve to be closed by the valve switching control means when the device vibrates. As a result, even if an ink liquid level in the reservoir changes when the device vibrates, transmission of this change to the meniscus of the ink discharging plane is prevented or suppressed.
