20090086220 | Image Forming Apparatus - A print method and apparatus for minimizing effects of error in repositioning during printing process may include generating successive scans of a recording head, wherein the scans may partially overlap to account for the error in repositioning. As an example, after the recording head makes one scan across the document being printed, the document (or the head) may be repositioned for the next scan so that several print elements of the recording head are aligned to lie between certain rows of dots printed in the previous scan, resulting in a higher number of rows in the overlapping portion of the scans. Additional features may include varying the row/column arrangement of dots in the overlap portion, or performing error diffusion and correction for different areas of resolution in the scans. | 04-02-2009 |
20090167796 | INKJET PRINTER - The invention provides an inkjet recording device comprising an ink cartridge receiving unit configured to receive an ink cartridge and an inkjet head configured to eject an ink. The inkjet recording device further comprising an ink passage configured to transport the ink from the ink cartridge to the inkjet head and comprising a detecting unit configured to detect a type of the ink cartridge received in the ink cartridge receiving unit. The inkjet recording device still further comprising a waste ink collection unit comprising an absorber configured to absorb the ink, and comprising a discharging unit configured to discharge ink remaining in the ink passage at one of a first discharging rate and a second discharging rate. Moreover, the inkjet recording device comprising a controller configured to control the discharging unit to discharge an amount of the ink. The controller is configured to control the discharging unit to discharge ink at one of the first discharging rate and the second discharging rate corresponding to the type of the ink cartridge detected by the detecting unit. The inkjet recording device may prevent or reduce ink coagulation due to mixing of different types of inks and may prevent or reduce the overflow of the waste ink tank. | 07-02-2009 |
20090237757 | IMAGE-PROCESSING SYSTEM - An image-processing system for printing an image based on original image data. The storing unit stores at least one look-up table in association with at least one printing condition. The at least one look-up table is used to convert a color value in original image data into a limited color value that limits a total quantity of ink to be used in printing. The detecting unit detects, as a printing condition, at least one of a type of color material and a type of recording medium which are used for printing operation. The converting unit converts the color value data into the limited color value by using a look-up table that is assigned with a printing condition corresponding to the detected printing condition. | 09-24-2009 |
