20080292376 | THERMAL FIXING DEVICE AND IMAGE FORMING DEVICE - The contact rate between a heater | 11-27-2008 |
20080291226 | RECORDING METHOD AND RECORDING DEVICE - For use when the recordable area of a recording medium is smaller than recording data, there is provided a recording device that can determine the priority of divided areas and preferentially record a high-priority area. The recording device assigns priority to each of the recording areas of a whole image on one page and, if it is determined that the whole image does not fit on the recording medium, performs at least one of rearranging the recording position of a high-priority area, changing the recording size of a low-priority area, and discarding a part of recording data of the low-priority area based on the priority of the recording areas to prevent any part of the image of the high-priority area from being lost. | 11-27-2008 |
20080273064 | INK-FEEDING DEVICE AND PRESSURE-GENERATING METHOD - An ink-feeding device is provided in which the pressure applied to the ink in the printing head can be adjusted arbitrarily irrespective of the relative positions of the ink container and the printing head. Inside the sub-tank | 11-06-2008 |
20080273046 | Ink Supplying Device, Recording Device, Ink Supplying Method and Recording Method - Variations in the negative pressure in the print head is minimized by positively controlling the ink supply pressure. For this purpose, the pump ( | 11-06-2008 |
20080266345 | INK JET PRINTING APPARATUS AND INK JET PRINTING METHOD - An object of the present invention is to provide an ink jet printing apparatus and an ink jet printing method which can prevent print quality from being degraded by a non-ejection nozzle while maintaining high-speed printing performance based on a raster division method. The present invention sequentially performs, array by array, an operation of ejecting ink through a plurality of nozzle arrays to sequentially print an image in a plurality of raster forming areas of a print medium. At this time, if an expected printing result fails to be achieved owing to a nozzle included in any of the nozzle arrays which exhibits degraded ejecting performance, degrading image quality, then the ejection order of the plurality of nozzle arrays is changed. This enables a reduction in the degradation of print quality caused by the ejecting performance of the nozzles. | 10-30-2008 |
20080259391 | RECORDING SYSTEM, CONTROL PROGRAM, AND RECORDING DEVICE - Recording data generated by a recording data generation PC ( | 10-23-2008 |
20080225064 | PRINTING SYSTEM - In a printing system including a plurality of inkjet printing units and an ink tank commonly used thereby, wherein the ink tank is capable of notifying an amount of ink consumed thereby and has a memory for storing information relating to the ink consumption amount in a updatable manner, the memory access by the printing units is properly arbitrated. The printing system is provided with a storage section for storing the ink consumption amount notified from the respective printing units, a process section for reading the information from the memory and carrying out the calculation together with the stored ink consumption amount, a process section for updating the content in the memory based on the calculated value, and a process section for suspending the calculation relating to the amount of ink consumption in one printing unit, when the calculation is being carried out about any other printing units. | 09-18-2008 |
20080218551 | INK JET PRINTING METHOD AND INK JET PRINTING APPARATUS - Time for which an ejection port surface of a print head has been exposed to the exterior since the end of the last cleaning operation is predicted and accumulated as an accumulated exposure time. A cleaning timing is set to be a timing when the accumulated exposure time coincides with a set time set according to the ambient temperature and humidity of an area in which a label printer is installed. In principle, a cleaning operation is performed at the cleaning timing. However, when the cleaning timing comes during the current consecutive printing operation, the cleaning operation is not performed during the current consecutive printing operation but at a time before the start of the current consecutive printing operation or a time after the end of the current consecutive printing operation. | 09-11-2008 |
20080218544 | INK-JET TYPE IMAGE-FORMING APPARATUS AND INK-JET TYPE IMAGE-FORMING METHOD - An image-forming apparatus is provided which prevents irregularity of an image density and improves the life of heating elements. In a half of recording heads (a group of recording heads | 09-11-2008 |
