20090002426 | INKJET IMAGE FORMING APPARATUS AND CONTROL METHOD THEREOF - An inkjet image forming apparatus sets an initial ink temperature according to a dot area of a dot-sized pattern printed by the printer head, and calculates an ink temperature by applying the initial ink temperature to a temperature conversion equation. The inkjet image forming apparatus prevents a measurement error of the temperature sensor from valid data after the printing process is terminated, so that it can correctly measure the ink temperature of the printer head. | 01-01-2009 |
20090002427 | METHOD OF DETECTING MISSING NOZZLE AND INK JET PRINT HEAD USING THE SAME - A method of detecting a missing nozzle and an ink jet print head using the same, that can detect a missing nozzle immediately with a simple process when the missing nozzle is generated. The method of detecting a missing nozzle used in an ink jet print head provided with plural chambers in which an ink is filled, plural heaters corresponding to the chambers, and plural nozzles corresponding to the heaters, can include detecting a temperature of each of the nozzles, and when the detected temperature deviates from a predetermined temperature range, determining that the nozzle is a missing nozzle. | 01-01-2009 |
20090015618 | INKJET IMAGE FORMING APPARATUS AND METHOD TO CONTROL THE SAME - An inkjet image forming apparatus includes a negative pressure controller in an ink supply flow path that connects an ink storage and a print head. The negative pressure controller includes a valve to open and close the flow path to control a negative pressure applied to the print head. If there is a need to cool the ink heated by a maintenance operation performed on the print head or to cool the ink heated by a print job, a controller in the apparatus controls the valve of the negative pressure controller to release the negative pressure applied to the print head so that the print head is filled with low-temperature ink from the ink storage. | 01-15-2009 |
20090015619 | INK SUPPLY DEVICE AND INKJET IMAGE FORMING APPARATUS HAVING THE SAME - An ink supply device to maintain temperature uniformity of ink via active heating and cooling of the ink, and an inkjet image forming apparatus having the same includes at least one thermoelectric element to adjust a temperature of ink to be supplied to an inkjet head. With heating and cooling of the thermoelectric element, preventing deterioration in image quality caused by a change of ink temperature and to achieve improved print quality is possible. | 01-15-2009 |
20090058913 | INK JET IMAGE FORMING APPARATUS AND METHOD OF CONTROLLING THE SAME - Temperature characteristic information of each line of a print image is established in a database, an initial value of a temperature sensor is corrected such that a difference between a temperature measured by the temperature sensor provided in a print head and a temperature estimated on the basis of the temperature characteristic information established in the database is in an allowable range, and a printing operation is performed according to the temperature measured by the corrected temperature sensor. Accordingly, it is possible to prevent printing quality from deteriorating due to a measurement error of the temperature sensor. | 03-05-2009 |
20090271447 | METHOD FOR SYNCHRONIZING CONTENTS FILE AND DEVICE FOR EMPLOYING THE SAME - A method and device for synchronizing a contents file are discussed. An embodiment is directed to a method for synchronizing data using a target device, the target device including a target contents file, the method comprising: receiving file information of a reference contents file from a reference device; comparing the file information of the reference contents file and file information of the target contents file to determine whether a contents file synchronization is needed; and synchronizing the target contents file using the reference contents file based on the comparison result. | 10-29-2009 |
