20090034993 | METHOD AND APPARATUS FOR FORMING IMAGE - A method and apparatus for forming an image determine if printing paper is properly picked up, and printing data is transferred to an intermediate transfer belt (ITB). When it is sensed that the printing paper is not properly picked up, picking up the printing paper is retried considering a revolution cycle of the ITB. Thus, the frequency of errors can be decreased, and a user's convenience can be increased because picking up the printing paper is automatically retried whenever mis-pick up occurs instead of displaying an error. Further, wasting of toner is decreased. | 02-05-2009 |
20090103961 | IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD THEREOF - An image forming apparatus and an image forming method thereof. The image forming apparatus includes an image forming part which forms a color image on a printing medium, a pickup roller which picks up the printing medium, and a controller which controls the pickup roller to try to pick up the printing medium if image forming for a first color among a plurality of colors is completed, and controls the image forming part to form an image corresponding to a second color among the plurality of colors after trying to pick up the printing medium. | 04-23-2009 |
20110142470 | Image forming apparatus and control method thereof - A method of controlling an image forming apparatus and method thereof including a medium feeder configured to load therein and to pick up and feed a printing-target medium; an image forming unit configured to form an image on the printing-target medium that is picked up and fed; and a fixing unit configured to fix the printed medium on which the image has been formed, the method including: heating the fixing unit such that a temperature of the fixing unit reaches a fixing reference temperature determined corresponding to the printing-target medium if an printing operation is started; sensing the temperature of the fixing unit corresponding to the start of the printing operation and compensating a pickup timing temperature corresponding to whether the sensed temperature thereof is higher or lower than a predetermined first reference temperature, the pickup timing temperature being a temperature for picking up the printing-target medium; and picking up the printing-target medium when the temperature of the fixing unit that is being heated reaches the compensated pickup timing temperature. | 06-16-2011 |
20130016985 | COLOR IMAGE FORMING APPARATUS AND CONTROL METHOD THEREOFAANM Son; Jung WooAACI SeoulAACO KRAAGP Son; Jung Woo Seoul KRAANM Kim; Suk GooAACI Namyangju-siAACO KRAAGP Kim; Suk Goo Namyangju-si KR - A color image forming apparatus and a control method thereof, in which a transfer start position of a transfer belt is determined based on electric signals that correspond to a width of a position indicator provided on a transfer belt and are detectable during one rotation of the transfer belt even when noise occurs in output, thereby reducing the overall printing time. | 01-17-2013 |
20130089353 | IMAGE FORMING APPARATUS TO ENHANCE PRINTING PERFORMANCE AND PRINTING METHOD THEREOF - An image forming apparatus to perform mono printing and color printing having different printing speeds and enhance printing performance includes an image forming unit to perform the color printing and the mono printing, and a control unit to determine whether to change a printing speed by comparing an amount of printing to be processed with a predetermined critical value and, if it is determined to change the printing speed, controlling the image forming unit to perform printing according to the amount of printing to be processed by switching a printing speed from printing at a relatively slow printing speed to printing at a relatively fast printing speed. | 04-11-2013 |
20130330095 | IMAGE FORMING APPARATUS AND COLOR TONE DENSITY CONTROLLING METHOD THEREOF - A method of controlling a color-tone density (CTD) of an image forming apparatus including a plurality of developers configured to circularly perform a developing operation. The method includes developing test patches on an OPC sequentially from a developer to be developable preferentially, measuring CTDs of the developed test patches, and controlling a development variable using the measure CTDs. | 12-12-2013 |
