The present disclosure relates an image correction apparatus and method. The image correction apparatus includes a printing unit for printing an image; a scratch detecting unit which detects a scratch region from a scan image scanned per line; and a restoration processing unit which performs the restoration of the scratch region by interpolation if the width of the scratch region detected by the scratch detecting unit is less than a predetermined value and, if the width thereof is not less than the predetermined value, does not perform a restoration of the scratch region but provides the printing unit with the scan image, thereby correcting an image distortion by easily detecting an image distortion due to foreign matter.

Image correction apparatus and method

Disclosed is a developer discharging device for an image forming apparatus, which is installed in a developing unit configured to transfer and discharge a developer collected from a drum unit or a newly introduced developer, such that the developer is discharged to a developer collecting unit, including a first discharging part configured to extend from an end of a transferring screw installed in the developing unit, and a second discharging part disposed above the first discharging part in parallel with the first discharging part, wherein the developer discharged from the second discharging part falls into the developer collecting unit. Therefore, it is possible to prevent the developer from being sharply discharged, and thus to constantly maintain an amount of the developer.

Developer discharging device for image forming apparatus

A cartridge assembly for an image forming apparatus, including a drum unit provided with a waste toner conveyor which conveys waste toner collected from a surface of a photosensitive drum to one side; a developing unit connected with the drum unit, configured to receive the waste toner collected from the drum unit, and having a developer discharger to discharge a developer therein to an outside; and a developer collecting unit integrally formed with the drum unit at one side of the drum unit, and configured to collect the developer discharged by the developer discharger of the developing unit, wherein the drum unit includes a toner injector which connects the waste toner conveyor, a new toner supply unit and the developing unit so that the waste toner conveyed by the waste toner conveyor and new toner supplied from the new toner supply unit are injected together into the developing unit.

Cartridge assembly and shutter assembly for image forming apparatus

An A4-size scanner capable of scanning an A3 document. The A4-size scanner includes a scanning part, a transferring roller member that is disposed at an upper side of the flat glass to be orthogonal to a length direction of the automatic document feeding unit and the scanning sensor so that the document having a double size of a scanning capacity of the scanning sensor and introduced onto the flat glass in the length direction of the automatic document feeding unit and the scanning sensor is transferred to a transferring roller, and a transferring roller member driving motor that is connected with the transferring roller which dividedly scans the document having a larger size than the scanning capacity of the scanning sensor; and an image processing part which performs an image processing for composing two images which are dividedly scanned through the scanning part.

A4-size scanner having function of scanning A3 document and scanning method thereof

An image forming apparatus is capable of scanning a document having a larger size than the flat. For example, it is possible to scan an A3 document using a scanning sensor having a slight larger size than an A4 document, and also it is possible to obtain a high quality of the A3 document image.

Image forming apparatus having scanning function and scanning method thereof

A method for controlling an automatic discharge of a paper jammed in a copy machine, capable of eliminating a requirement for a user to directly remove the jammed paper. The method provides provides three jam removal modes, that is, an automatic jam removal mode for performing automatic try for removal of jam, a semi-automatic jam removal mode for performing a try for removal of jam when the user presses down the copying start key, and a manual jam removal mode for stopping the copy machine upon generation of jam, as in existing copy machines, thereby preventing deterioration of driving parts of the copy machine such as abrasion of rollers caused by forced discharge of the jammed paper, enabling the user to directly remove without opening a door of the copy machine while minimizing contamination of development and fixture parts of the copy machine and damage of driving parts of the copy machine, and capable of displaying signs indicative of a jam removing state and a manual removal of jammed papers, thereby enabling the user to recognize the state of the copy machine, and thereby obtaining a convenience in use.
