A display device includes a cradle and a display module. The cradle includes a signal transmission unit configured to transmit an image signal, a housing exposing the signal transmission unit. The display module has a curved shape along a radius of a curvature and includes a signal reception unit configured to receive the image signal, an image display unit configured to display an image based on the image signal, and a second coupling member. The display device is configured to operate in any one of a first state and a second state, in which during the first state, the cradle and the display module are decoupled from each other, and in which during the second state, the first coupling member and the second coupling member are slide-coupled to each other, such that the display module moves along the circumference of a circle of the curvature of the display module.

A method of controlling performance of auto color registration (ACR) of a color image forming apparatus, and an image forming apparatus using the same are provided. The method of controlling performance of ACR includes forming a composite black image on a transfer belt, sensing the composite black image by using a sensor, measuring the sensed composite black image, and performing ACR correction when a measured width of the composite black image is greater than a previously set value. Accordingly, it is possible to prevent unnecessary performance of ACR control when no color misregistration has occurred. In this way, ACR control is performed in as short a time as possible so that performance of the image forming apparatus may be improved. Also, it is possible to prevent waste of ACR performance time and life span reduction of a driving source for ACR.

Method of controlling performance of auto color registration and image forming apparatus using the same

An image forming apparatus includes an input unit to receive printing data, a controller to determine a duplex printing mode to be applied to the printing data from among a plurality of duplex printing modes and an engine waiting time according to a feature of the input printing data and performance of the image forming apparatus, an image processor to perform image-processing of the input printing data, and an image former to print the image-processed printing data based on the determined duplex printing mode and the determined engine waiting time.

Image forming apparatus and method of image forming

An image printing method of a host apparatus connected to an image forming apparatus, the method includes selecting an image to be successively printed over a plurality of recording pages, disposing the image to be successively printed on at least one of top, bottom, right and left positions of at least one of the plurality of recording pages, generating printing data of the image to be successively printed over the plurality of recording pages, and transmitting the printing data to the image forming apparatus.

System and printing method to generate printing data of an image to be printed over a plurality of recording pages

A printing method usable with an image forming apparatus includes initiating driving of a plurality of photosensitive bodies and a transfer belt, printing an image by transferring toner images formed on the plurality of photosensitive bodies to the transfer belt and finally transferring the toner images, which are transferred to the transfer belt, to paper, and stopping the driving of the plurality of photosensitive bodies and the transfer belt after the printing is completed. The initiating of the driving of the plurality of photosensitive bodies and the transfer belt includes applying drive initiating signals with a time interval to a first driving unit and a second driving unit to respectively drive the plurality of photosensitive bodies and the transfer belt to enable the plurality of photosensitive bodies and the transfer belt to simultaneously begin rotating/moving.
