20100156973 | PRINTING APPARATUS AND PRINTING METHOD - The present invention has an object to provide an inkjet printing apparatus that can realize both high quality image formation and improvement of a device life caused by the reduction of a mist amount of a processing liquid. The present invention is provided with a control unit that can independently control an ink ejection condition in an ink ejection unit and a processing-liquid ejection condition in a processing-liquid ejection unit. The control unit controls the ejection condition in each ejection unit so that the mist amount of the processing liquid ejected from the processing-liquid eject unit is smaller than that of the ink ejected from the ink eject unit. | 06-24-2010 |
20100156978 | INKJET PRINT APPARATUS AND INKJET PRINT METHOD - The present invention relates to a print apparatus for performing a print by a scan of a print head with heaters generating thermal energy for ejecting ink. A temperature of the print head is detected before the scan of the print head, and when the detected temperature exceeds a threshold temperature, the print head is waited. Information relating to the cumulative number of drives of the heater in the print head is acquired and based upon this information, the threshold temperature is changed to a lower temperature as the cumulative number of the drives is the larger. An excessive temperature rise of the head is restricted and also a throughput reduction is reduced as much as possible. | 06-24-2010 |
20100214353 | INK JET RECORDING APPARATUS - Suitable preliminary discharge conditions are set for a recording head using reaction liquid in bidirectional recording. While the recording head makes a reciprocating motion and scans a recording medium, a preliminary discharge of the reaction liquid is executed after recording on the recording medium from discharge ports on the rear side in a direction in which the recording head travels and a preliminary discharge of ink is executed when a preliminary discharge of the reaction liquid is not executed. | 08-26-2010 |
20100302297 | INKJET PRINTING APPARATUS AND METHOD OF CONTROLLING THE SAME - The invention prevents inconveniences from being caused by ejection failure and unintended mixing of different colors. To this end, the invention performs preliminary ejection of ink after a wiping action to sweep mist adhering to a face of a printing head, in which an ejection opening is formed. Moreover, the amount of ink to be wastefully consumed by the preliminary ejection after the wiping is reduced. To this end, the number of preliminary ejections is regulated. The degree of adherence of mist to the ejection-opening-formed face depends on the amount of printing (the number of printed sheets, the number of ink ejections for printing, or the like). So, at the time of the preliminary ejection after the wiping, the number of ink ejections in the preliminary ejection is regulated in accordance with the amount of printing that has been done since the last wiping action. | 12-02-2010 |
20110181645 | RECORDING APPARATUS - A recording apparatus includes a first acquisition unit configured to acquire a speed of ink discharged from a recording head, a second acquisition unit configured to acquire information relating to a speed change based on the speed acquired by the first acquisition unit and a reference speed; a setting unit configured to set driving information relating to the recording head based on the information relating to the speed change acquired by the second acquisition unit, and a drive unit configured to drive the recording head based on the driving information set by the setting unit. | 07-28-2011 |
20130027455 | PRINTING APPARATUS AND PRINTING METHOD - A printing apparatus includes a print unit, an acquisition unit, and a setting unit. The print unit performs printing on a sheet by repeating reciprocating scans of a print head. The acquisition unit acquires information on a temperature of the print head. The setting unit sets a wait time to start a next scan after one scan. The setting unit increases the wait time by a predetermined additional time for each subsequent scan once a value acquired by the acquisition unit exceeds a first threshold, unless the value falls below a second threshold. | 01-31-2013 |
20130027456 | PRINTING APPARATUS - A printing apparatus, which includes a heating unit for heating a recording medium during printing, determines a pass number for multi-pass printing based on acquired information relating to the duty in each of a plurality of regions in one band of print region. The printing apparatus sets an amount of heat of the heating unit based on the acquired information. | 01-31-2013 |
20130147868 | INK JET RECORDING APPARATUS - The present invention relates to an ink jet recording apparatus including a recording head including a plurality of energy generation elements configured to generate thermal energy. The ink jet recording apparatus includes a specification unit and a control unit. The specification unit specifies a pulse width upper limit value of a prepulse during a recording operation based on a minimum pulse width by which ink is discharged by applying a drive pulse to the energy generation elements and a temperature of the recording head during the recording operation. The control unit controls the energy generation elements to be driven using a drive pulse of a prepulse with a pulse width equal to or less than the pulse width upper limit value. | 06-13-2013 |
20130235104 | INKJET PRINTING APPARATUS AND DRIVING METHOD - Provided are an inkjet printing apparatus, whereby pulse drive periods and a pause period can be adjusted so as to fall within predetermined periods, while the volume of ink to be ejected is ensured, and a heat generating element driving method therefor. For the inkjet printing apparatus, a pulse signal drive period for a pulse driven previously, a pulse signal drive period for a pulse driven subsequently and a pause period are set to perform ejection of ink droplets one time. When the ejection period exceeds the threshold value, the pulse signal drive period for the pulse driven subsequently and the pause period are reduced to adjust the ejection period to be equal to or lower than a threshold value. | 09-12-2013 |
20130257933 | INKJET RECORDING APPARATUS - An inkjet recording apparatus predicts the volume of air bubbles generated in a storage section of a recording head based on an input recording job. When the volume of the amount of ink in the storage section of the recording head is less than the predicted volume of air bubbles, a recovery operation is performed. | 10-03-2013 |
20150022574 | PRINTING APPARATUS AND PRINTING METHOD - An inkjet printing apparatus which performs printing by performing scanning using a print head has a problem in that quality of an image of a ruled line is degraded when ink is not ejected for a certain period of time. To address this problem, control is performed such that power for driving the print head for unit regions including pixels having a ruled-line attribute becomes higher than power for driving the print head for unit regions which do not include the pixels having the ruled-line attribute. By this, a high-quality ruled-line image may be printed. | 01-22-2015 |

20130237000 | METHOD OF MANUFACTURING SOLAR CELL MODULE - An aspect of the invention is a method of manufacturing a solar cell module in which wiring members are electrically connected to front and back electrodes on front and back sides of a solar cell with resin adhesion films. The total area of the front electrode is smaller than that of the back electrode. The method includes: arranging the resin adhesion films on the front and back electrodes; arranging a first cushion sheet and a lower press member below the lower resin adhesion film and arranging a second cushion sheet being thicker than the first cushion sheet and an upper press member above the upper resin adhesion film; pressing the press members against each other thereby bonding the resin adhesion films to the solar cell; and releasing the pressure to the press members and moving the first and second cushion sheets away from the solar cell. | 09-12-2013 |
