Abstract: An image forming device having a resolution compensation function comprises a storage for storing scaling information and resolution information with respect to printing data, a controller for setting a resolution of scaled printing data to a specific resolution based on the scaling information, and a print engine for forming an image of the received printing data according to the resolution set by the controller. The image forming device (such as a printer, a facsimile machine, or a copier) minimizes the degradation of the image quality when scaling an image to be printed or copied. Furthermore, the degradation of the scaled image quality is reduced when the image forming device is directly connected to a USB compatible storage medium or an image capturing device such as a digital camera, or a digital camcorder, and the image forming device receives and prints an image from the connected storage medium or the image capturing device.

Abstract: A method and an apparatus for indicating the time to replace consumables in an image forming apparatus by receiving the current date and the critical time of the consumables from a host and comparing them. The apparatus and method include receiving information regarding replacement of the consumables from the host; comparing the received information regarding the replacement of the consumables to information on the critical time to replace the consumables; and when the comparison result indicates the need to replace the consumables, indicating the time to replace the consumables. The information regarding replacement of the consumables includes a current date, and the information on the critical time includes the critical time. The indicating of the time may include comparing the current date and the critical time and when the current date is the same as or greater than the critical time, determining that the consumables need to be replaced.

Abstract: Disclosed is a method for removing contaminants which remain on an engine of an image forming apparatus, such that when a sheet of paper becomes jammed in the image forming apparatus during a printing operation, a subsequent sheet of paper is enforcedly supplied to the image forming apparatus after removing the jammed paper so that contaminants, for example toner, are removed from the image forming apparatus in such a manner to fix the contaminants to the subsequent sheet of paper. While fixing the contaminants to the subsequent sheet of paper, print data is not fixed onto the subsequent sheet of paper. Accordingly, an optimum quality of printing can be accomplished without a waste of toner.

Abstract: A method for detecting the status of the toner in a laser printer uses a photosensor. The method includes sampling a signal generated from the photosensor during a specified time, increasing or decreasing the value of a counter in accordance with an integral algorithm, and comparing the resultant counter value with a reference value, and displaying the status of the toner in the printer on a display device, depending on a result of such comparison. This method can accommodate relatively inexpensive photosensors. As the noise-ridden signal generated by such a photosensor is effectively filtered, this method is advantageous in cost and reliability.
