Abstract:
The present application is directed to devices and methods for moving media sheets in an image forming device. In one embodiment, a contact member includes a contact roller that contacts a top-most media sheet in a stack of media sheets positioned on a support surface in an input area of the image forming device. A hub extends outward from an axial side of the contact roller. The hub includes a smaller length than the contact roller, forming a gap between the hub and the top-most media sheet when the contact roller is in contact with the top-most media sheet. The hub prevents or reduces transverse buckling of the top-most media sheet when it is moved from the stack of media sheets.
