Control Of Separator Responsive To Sensing Of Sheet Patents (Class 271/110)
  • Patent number: 11014384
    Abstract: A pick attempt of a media sheet from a media tray is initiated by rotating a pick roller a number of rotations that is set to greater than one in response to the sheet having been designated as a special media sheet type and that is set to one in response to the sheet not having been so designated. In response to a pick sensor detecting the sheet after the pick attempt has been attempted, a turn roller is rotated to advance the sheet to a print engine, and while the turn roller is rotating, the pick roller is rotated to assist advancement of the media sheet. A controller manages per-sheet and per-tray pick attempt counters while the sheet is individually attempted to be picked and advanced, using the counters to determine whether to initiate another pick attempt of the sheet when a current pick attempt has failed.

A user can insert a stack of banknotes into an automated teller machine. A pair of opposing clamping surfaces can apply pressure to the stack of banknotes. An array of pressure sensors can sense non-uniformities in pressure over the area of the array. If circuitry coupled to the pressures sensors senses a presence of a high pressure area in the surface area of the banknotes, then the circuitry can generate a signal indicating that one or more foreign objects has been detected. The automated teller machine can then prompt the user to remove the stack of banknotes and remove the foreign object from the stack of banknotes.
