摘要： A recording device drives a recording head mounted on a carriage while main-scanning by moving the carriage in a direction generally orthogonal to the sheet-feeding direction of a sheet. The recording device drives a first nozzle of the recording head at an upstream side in the sheet-feeding direction of the sheet to form a first dot pattern while scanning the carriage and drives a second nozzle at a downstream side in the sheet-feeding direction of the sheet to form a second dot pattern. The recording device feeds a region where the first dot pattern is recorded to a position facing the second nozzle. The second dot pattern is recorded in a region where the first dot pattern is not recorded.

摘要： The object of this invention is to provide a printing apparatus and printhead temperature retaining control method capable of suppressing power consumption, and reducing degradation in image quality. To achieve the object, a printing apparatus for printing an image on a printing medium by discharging ink, executes the following processes. A first temperature adjustment process is executed to adjust the printhead temperature to a first adjustment temperature during the non-printing period in which preparation for printing the image is executed by discharging ink from the orifices. Additionally, a second temperature adjustment process is executed to adjust the printhead temperature to a second adjustment temperature during a printing period in which the image is printed on the printing medium by discharging ink from the orifices. The process is executed while providing a quiescent period without printhead temperature adjustment between the first and second temperature adjustment processes.

摘要： The present invention provides an ink jet printing apparatus and a method for controlling temperature for the ink jet printing apparatus wherein the temperature of a print head, which may lower during printing, is controlled before printing without using any sub-heater to allow a favorable ejection condition to be established without reducing the head temperature below a predetermined value. Thus, scan width information and dot count information are acquired before a carriage starts scanning to determine the heating temperature of the print head on the basis of the information.

摘要： A printing apparatus prints on a printing medium by using a printhead which has a first nozzle array including a plurality of nozzles from which a first nozzle amount of the ink is discharged and a second nozzle array including a plurality of nozzles from which a second nozzle amount of the ink is discharged. This printing apparatus time-divisionally drives a plurality of blocks obtained by dividing each of the first nozzle array and the second nozzle array. The printing apparatus selects, from the first nozzle array and the second nozzle array, a block to be driven by the driving unit within a predetermined period. This printing apparatus controls the selection unit to alternately select a block from the first nozzle array and the second nozzle array and sequentially select a block from each nozzle array in a predetermined order.

摘要： In an inkjet printing apparatus utilizing an inkjet head and an ink tank for supplying ink to the same, it is made possible to suppress any reduction in image quality attributable to changes in physical and chemical properties of the ink that occur during an elapsed time from the manufacture of the ink tank to the use of the same, thereby allowing images to be formed with high reliability and stability at a low running cost. The apparatus has a discharging unit for discharging the ink through a nozzle at the head and an ink detecting unit for detecting the consumption of the ink in the ink tank. The detected ink consumption is compared with a threshold for ink consumption appropriately determined based on the elapsed time, and control is performed such that the amount discharged by the discharging unit is increased when the ink has not been consumed sufficiently.
