    Abstract: A transfer device and an image forming apparatus having the same are provided. Shapes of cam profiles of first cam members and second cam members controlling movement of first slider members moving a first transfer roller corresponding to a black developer, and second slider members moving a second transfer roller corresponding to a color developer. Times are different as when movement of the first slider members is completed and when movement of the second slider members is completed in mode conversion among a ready mode, a mono mode and a color mode, and thus a driving load generated when the first and second cam members are rotated is reduced, non-uniformity of the rotating speeds of the first and second cam members is reduced, and problems generated due to non-uniform rotating speeds of the cam members are reduced.

    Abstract translation: 提供了一种转印装置和具有该转印装置的图像形成装置。 控制第一凸轮构件的凸轮轮廓和第二凸轮构件的形状,其控制移动对应于黑色显影剂的第一转印辊的第一滑动构件的运动,以及移动对应于彩色显影剂的第二转印辊的第二滑动构件。 时间是不同的,因为当第一滑块构件的移动完成并且当准备模式,单声道模式和彩色模式之间的模式转换中第二滑块构件的移动完成时,并且因此当第一和第二滑块 凸轮构件旋转减小,第一和第二凸轮构件的旋转速度的不均匀性降低,并且由于凸轮构件的不均匀旋转速度而产生的问题减少。

    Abstract: A method and a system for providing a Wireless Fidelity (Wi-Fi) service, in which when multiple counterpart devices are selected based on manufacturer information and support information on supported functions and capability defined in a service information field of each beacon message or each probe response message, a final device is determined by checking multiple pieces of signal information of the selected counterpart devices, are provided. The method includes receiving messages from multiple counterpart devices, selecting one or more counterpart devices, each of which supports a requested service, from an identical manufacturer when the messages are received, checking multiple pieces of signal information of the selected counterpart devices when the number of the selected counterpart devices is greater than one, and determining a device having the signal information satisfying set conditions as a final device.
