摘要： A sheet supply station for a compact printer of the type having a housing, a feed/transport member which is rotatably mounted within a forward portion of the housing and is adapted to sequentially move sheets from a supply location at the bottom of the housing, through the print zone and out an egress in the upper surface of the housing. The sheet supply station comprises: (a) a drawer, including a drawer face and a drawer bottom, which is constructed to support a sheet stack and slidably mounted for movement in and out of the rear wall of the printer between a withdrawn position enabling stack insertion and a closed position wherein the drawer face is approximately flush with the rear wall; (b) side guides for engaging and centering a sheet stack, which is supported on the bottom wall, during its movement into the housing from the withdrawn drawer position; and (c) an indexing wall located transverse to the drawer path to accurately position an inserted stack beneath the feed/transport member. Sheet buckling structures are provided for reliably feeding single sheets sequentially from the top of a sheet stack.

摘要： A printer/feeder apparatus of the type having: (i) a feed/transport platen rotatable so that its peripheral surface moves past a sheet supply zone, a print path ingress, a print zone and a print path egress; (ii) frictional feed surface located on a peripheral sector of the platen surface and (iii) means for selectively effecting feeding engagement between the face sheet(s) of a stack of sheet media and the feed surface features a detection/control system that includes (a) a first detector for sensing and signalling when and when not a forward edge of the feed surface is at a predetermined start position; (b) a second detector means for sensing and signalling when and when not engagement condition exists; (c) a third detector means for sensing and signalling when and when not a sheet is located along a predetermined portion(s) of the print path; and (d) a control system for receiving signals from the detectors and enabling printing cycles and signalling error conditions.

摘要： A print media handling system for a compact printer having a housing, a cut-sheet supply station, a rotatable print platen constructed and located to feed top sheets from the supply station, through a print path ingress and out a print path egress. The sheet supply station of the print media handling system is mounted for movement to and from a sheet engaging relation with respect to the print platen. A continuous print-media inlet passage extends from a location, that is spaced from the sheet supply station, to the print path ingress and an actuator is provided synchronously enable the supply station and block the continuous media inlet passage, or vice versa. A first program control effects a predetermined start-print sequence for sheet print media, a second program control effects a predetermined start-print sequence for continuous print media; and the first or second program control is selected in response to the condition of the actuator.
