  • Sheet constraint
    Patent number: 7810803
    Abstract: An apparatus in an example comprises a sheet holder, a separator surface, a feed head, and one or more arms. The sheet holder supports one or more sheets of media. The separator surface receives a leading edge of a sheet of the one or more sheets of media. The feed head is selectively positionable against a face of the sheet. The one or more arms extend toward an intermediate location of the separator surface to constrain the sheet from movement away from the separator surface.
